Plastic optics boosted to 25 Gbit/s
R. Colin Johnson5/23/2011 2:50 PM EDTPORTLAND, Ore.–A new vertical-cavity surface-emitting laser (VCSEL) technology from VI Systems aims to extend the reach of cheap plastic fiber optics, with scientists at Georgia Institute of Technology reporting successful operation at 25 Gbits per second.

VI Systems(Berlin) reports that it has achieved 40 Gbit/s in the lab and is aiming for 100 Gbit/s performance.

Georgia Tech's demonstration used VI Systems' VCSEL at 850 nanometers wavelength, transmitting at 25 Gbit/s over a long 100 meter plastic fiber. This compares to plastic fibers typical use for shorter runs and 650 nanometers wavelengths at speeds up to 1 Gbit/s in home networks and as slow as 50 Mbit/s for in-car automotive networks. As a result, VI System predicts that these and similar cost-sensitive applications can now boost their performance up to the 40-to-100 Gbit/s range.

Georgia Tech reported that its transmission demonstrations were error free over cables with 80-micron core plastic optical fiber using relaxed coupling tolerances as high as 35 microns. In the lab, VI Systems reports speeds up to 40 Gbits/s when coupled with high-speed photodetectors and transimpedance amplifiers.

Individual VCSELs fit on a 250 micron square die, but can also be obtained from VI Systems in 1-by-4 or 1-by-12 arrays for proprietary home and automotive networks, as well as for Fibre Channel, Infiniband and other high-speed applications.

新闻大意，VI公司和乔治亚工学的科学家利用垂直腔表面发射激光器VCSEL技术实现了在廉价塑料光纤上运行25Gbps速率，并且距离超过100米。通常塑料光纤船速距离很短，家庭网络的速率只能到1Gbps，车载网络的速率只到50Mbps。在实验室，使用高速光检测器和跨阻放大器甚至实现了40Gbps的速率。这类应用有望在Fiber Channel,Infiniband和其他高速应用中。

ClariPhy samples 40G coherent chip
Rick Merritt5/23/2011 3:29 PM EDT

SAN JOSE, Calif. – Startup ClariPhy is sampling a single CMOS chip aimed at lowering the cost of upgrading long distance optical networks to 40 Gbits/second. The chip is part of a rising tide of silicon for next-generation carrier and data center networks at 40 and 100 Gbit/s data rates.

Carriers are coming to agreement that the next-big step for their long haul networks is 40G transport using dual-polarization QPSK, a coherent form of optical modulation, said ClariPhy founder and chief technology officer Norm Swenson. Standards have been set for DP-QPSK at both 40 and 100G nets, he said.

"There have been many attempts at how to handle [optical long haul upgrades], but now people have gelled on this approach," said Swenson.

The coherent technology "treats light like a radio wave, making use of phase and amplitude information," said Swenson. Designers can use the phase information—lost in today's direct detection technology—to handle several forms of optical signal dispersion in a single CMOS DSP.

Current systems based on direct detection of the light signal use additional components, sometimes requiring additional line cards, to improve the quality of optical signals sent over long distances. The coherent technique also can improve signal sensitivity by using a local oscillator, Swenson said.

ClariPhy has been working for two years on its 40nm chip which is now integrated in customer systems, some of which may already be used in carrier tests. The chip dissipates about 16W and is based on the company's own internally developed analog-digital converter and DSP technology.

The startup hired a signal processing expert early on who created a DSP lab in Argentina. It has analog expertise at its headquarters in Irvine, Calif.

"I worked on a coherent system 10 years ago, but it was all discrete components," said Swenson. "Now you can design a single chip that can do this if you have a very good analog-to-digital front end," he said.

The ClariPhy chip will be in production this fall. At least one other company is expected to debut a 40G coherent chip soon.

新闻大意，初创公司ClariPhy虽然小，但很牛。在DP-QPSK技术上采用了单片cmos芯片来实现40Gbps的光传输。ClariPhy的核心技术是cmos DSP，以及自行研发的ADC。简单来说，集成是唯一的途径。

PMC-Sierra offers SoC for 40-Gbps DP-QPSK coherent designsby Stephen Hardy
May 24, 2011

PMC-Sierra (NASDAQ

MCS) has taken the first major step towards evolving designs leveraging dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection away from discrete electronic elements towards off-the-shelf system on a chip (SoC) devices. The company’s new PM6373 POLO 40G integrates SerDes, digital signal processing (DSP), analog-to-digital converter (ADC), OTN framing, and Forward Error Correction (FEC) functions for use in 40-Gbps designs. The obvious question, of course, is when PMC-Sierra plans to tackle 100 Gbps.

Jay Bennett, manager, marketing within PMC-Sierra’s Communications Products Division, says the POLO 40G will enable significant reductions in 40-Gbps line card density (2X) and power consumption (50%) versus non-coherent approaches, in part because the use of coherent detection obviates the need for bulky tunable dispersion compensation devices.

The SoC also offers an alternative to the few coherent-friendly ICs now available as multi-chip offerings from companies such as Cisco/CoreOptics. The POLO 40G SoC chip is designed to dissipate 16 W. Bennett estimates that a multi-chip approach would dissipate at least 3X more power and perhaps as much as 5X.

The POLO 40G leverages PMC-Sierra’s Swizzle FEC technology, which Bennett described as a hard-decision FEC with 18.8% overhead that provides +2 dB of improved performance.

Bennett says PMC-Sierra has targeted both line card and module applications for the device. The POLO 40G could be integrated within an OIF-compliant 5x7-inch module or placed behind CFP2 modules. He admitted he also has his eye on opportunities to replace CoreOptics chips. He sees a significant opportunity to support 40-Gbps transmission in packet-optical transport platforms, OTN systems, and Carrier Ethernet switch/routers or label switched routers with integrated DWDM shelves, such as Juniper Networks’ recently announced PTX Series Packet Transport Switch.

PMC-Sierra plans to have sample devices ready for selected customers in the third quarter of this year, with general availability shortly thereafter. A POLO 100G would appear the next likely step. Bennett would not comment on PMC-Sierra’s plans for 100-Gbps SoCs, other than to acknowledge such a device would make sense.

这个可是大新闻。目前的40G DQPSK transponder都是基于分离器件，而且价格不菲，如果PMC-Sierra能成功实现SOC的话，无疑是一大进步。

PM6373 POLO集成了SerDes，DSP，ADC，OTN和FEC。比起非相干传输，POLO 40G显著减少了2倍的线卡密度，功率减少了一半。POLO 40G的功耗为16W，比起多个芯片的方案，比如来自Cisco/CoreOptics，功耗只有1/3～1/5。使用的FEC带来了18.8%的开销，但提供了2dB的增益。

该器件只选择性的在Q3提供样品。

NeoPhotonics unveils PIC-based small form factor DQPSK demodulator for 40Gbps systemsby Courtney Howard
May 25, 2011

NeoPhotonics Corp., a designer and manufacturer of photonic integrated circuit (PIC)-based modules and subsystems for bandwidth-intensive, high-speed communications networks, announced volume production of its PIC-based small form factor DQPSK demodulator, designed for use in 40Gbps direct-detection, fiber-optic transport systems.

The small form factor version is less than half the size of the standard form factor DQPSK demodulator, conserving board space in high-capacity systems.

The NeoPhotonics demodulator product is designed for use in 40Gbps direct detection Differential Quaternary Phase Shift Key(DQPSK) data transmission. DQPSKsystems utilize Delay-Line Interferometers (DLIs) to mix the incoming signal with a delayed sample, avoiding the need for, and cost of, an external local optical reference laser.

The NeoPhotonics DQPSK demodulator integrates two DLIs on a single photonic chip and provides in-phase and quadrature analysis of the phase-encoded signal. The NeoPhotonics DQPSK demodulator is designed to exhibit low sensitivity to polarization variations to accommodate the unpredictable and varying nature of the received signals.

“The deployment of 40 Gbps and 100 Gbps transmission technologies on the line side places stringent requirements on the optical performance of the components used. For example, the level of polarization dependence in our 40Gbps DQPSK demodulator must be much less than that of our typical 10Gbps products,” explains Tim Jenks, chairman and CEO of NeoPhotonics. “By using our photonic integration technology, we are able to achieve the high levels of optical performance and quality critical for these very high speed systems.”

光子集成厂商NeoPhotonics 宣布量产40G DQPSK解调器，尺寸是现有解调器的一半。该解调器在一个芯片中集成了2个延迟线干涉仪 DLI，对极化的依赖甚至比其传统的10G产品还低。

AMCC uses 25G signals to hit 100G
Rick Merritt 5/27/2011 8:00 AM EDT SAN JOSE, Calif. – Applied Micro Circuits Corp. announced a multiplexer for 100 Gbit/second networks supporting serial data rates up to 28 Gbit/second. The S28010 Gearbox is part of a wave of chips that aim to enable next-generation optical networks, and one of the first CMOS chips to support 28 Gbit/s signaling.
The S28010
is the first of a new family of high-speed optical networking chips AMCC plans. It translates a 10-lane, 10 Gbit/s CAUI electrical interface to four lanes operating at 25 Gbits/s, a data rate the latest CMOS silicon is just beginning to tackle for the first time.
The 40nm chip probably will see its first use in OTU-4 optical transport networks, but eventually could be used in data centers to carry 100G Ethernet, Fibre Channel or Infiniband traffic. The part is among the first devices to comply with both the IEEE 802.3ba standard for 40/100G Ethernet and CFP multi-source agreement for 40/100G modules.
Existing multiplexers that handle 28G serial data rates typically are made in BiCMOS or silicon germanium, require at least two chips consuming a total of up to 8W and cost about $1,000. The S42810 is a single chip that consumes less than 4W and will cost $750 when it samples in September.
The first generation of 100G optical networking chips generally used ten lanes running at 10G, but the parts were relatively large and power hungry. "Everyone believes four lanes of 25G is going to be where the future is, and in four or five years it will be mainstream," said Tim Warland, a product manager at AMCC.
The multiplexer sits on a CFP module and takes in 10G signals, typically from a network switch chip. It spits out four 25G channels and links to an optical module, sending data over distances up to 10 kilometers on a single-mode fibre.
The chips will be used in core routers for carrier networks or aggregation switches in large data centers, both interested in moving up to 100G data rates. AMCC has an early lead in the shift from the old Sonet standard to the newer Optical Transport Network (OTN) technology carriers are adopting.
The company claimed earlier this year it hit a milestone of enabling with its chips one million OTN ports to date. Volumes of the new CFP modules are ramping up to tens of thousands per month now and will hit a quarter million modules per month soon, said Warland.
Applied Micro has an estimated market share of 45 percent in OTN devices such as framers, mappers and physical-layer devices, according to market watchers at The Linley Group (Mountain View, Calif.).

AMCC是网络芯片的大牛之一，采用cmos工艺推出了10:4 100G mux芯片，符合802.3ba和CFP规范。而现有的方案是采用SiGe工艺，比如SMI10021就是采用IBM 8HP工艺，功耗8W，价格超过1000美金。而S28010功耗只有4W，价钱主要700美金，9月份可提供样品。
第一代的100G网络普遍采用10x10架构，但尺寸和功耗都很大。业界人士普遍认为25x4是未来，4～5年后将成为主流。AMCC约占OTN器件份额的45%，早些时候宣称OTN端口出货量超过100万，而CFP模块很快也将达到25万的月出货量。

VCSEL-based 25-Gbps transmission at 850 nm nearing readinessby Stephen Hardy
June 24, 2011

While module developers work to perfect 4x25-Gbps transmission over singlemode fiber for 100GBase-LR4 and -ER4 applications, technologists have already begun work on enabling similar transmission over multimode fiber. Recent demonstrations have shown progress on both the transmission and reception ends of the spectrum. The demonstrations indicate that 4x25-Gbps products could be readily available once standards are in place.

For example, Discovery Semiconductors displayed at OFC/NFOEC a module-based receiver with a photodiode based on InGaAs/InP for these applications. The company followed its OFC/NFOEC activity with more information in a paper at the subsequent “Enabling Photonics Technologies for Defense, Security, and Aerospace Applications” conference sponsored by the SPIE. The paper described three 25-Gbps, 850-nm receiver formats: linear photodiode (PIN), linear photoreceiver (PIN-TIA), and limiting photoreceiver (PIN-TIA-LIM). The paper describes the first as good for instrumentation applications, the second for low-power VCSEL-based 850-nm links that need boosted RF output power to drive the following RF electronics, and the third for on-off links that require sufficient gain to drive the following clock and data recover (CDR) or demultiplex modules often found in digital links. The PIN-TIA-LIM device in particular showed good performance (BER of 10-12 at an OMA of -4 dBm) over 100 m of OM3 fiber.

Abhay Joshi, president and CEO of Discovery Semiconductors, told Lightwave that his company has supplied photoreceiver technology for 25-Gbps, 850-nm research to a variety of laboratories, universities, and others working on the next generation of multimode transmission. At least some of that research likely is directed at the complementary VCSEL technology. Joshi says that pretty much everyone who has a 10-Gbps capable VCSEL is working on a 25-Gbps, 850-nm version. He expects such devices to be commercially available from multiple sources in the 2013-2014 timeframe.

One such supplier could be Germany’s VI Systems GmbH. VI Systems and partner Draka Communications Inc. reported June 8 that they had demonstrated error-free data transmission at 25 Gbps over 300 m of Draka MaxCap-OM4 fiber using multimode VCSELs. They also reported error-free transmission over 500 m of OM4 fiber with a received optical power of -6 dBm using singlemode VCSELs.

Joshi expects the first applications for 4x25 Gbps over multimode to be either optical backplanes or active optical cables. However, in addition to the necessary technology, standards also must be in place for a market to develop, Joshi allowed. Those could come from the IEEE for Ethernet or from the InfiniBand and Fibre Channel communities. The OIF’s CEI-25/28G backplane work also could create demand for a single-channel 25-Gbps VCSEL-based capability.

The aerospace industry also has expressed interest in the technology, Joshi concluded.

Discovery Semiconductor展示了分别用于仪器的PIN，作为功放的PIN-TIA，以及有足够增益可驱动clock/CDR单元或解复用器的PIN-TIA-LIM，后者在100m OM3光纤上传输时，在OMA为-4dBm上BER为10-12。

德国的VI system在6月8日展示了 300m MaxCap-OM4光纤上25Gbps的无误吗传输，同时可在500m OM4上接收光功率为-6dBm时利用单模VCSEL实现无误吗传输。

预计第一个4X25Gbps多模应用会在光背板或有源光缆上实现。以太网，Infiniband ，Fiber Channel是最有可能的应用。CEI-25/28G背板也会创造单通道 25G VCSEL的需求。

China Telecom deploys Huawei 100-Gbps DWDM systemsJune 23, 2011

A day after announcing KPN as a 100-Gbps customer (see “KPN International deploys Huawei’s coherent 100-Gbps WDM system”), Huawei disclosed that China Telecom also has deployed its 100-Gbps WDM technology, between metropolitan hubs Nanjing and Wuxi in the Jiangsu province of the Yangtze River Delta.

Huawei has supplied its 80-channel OptiX OSN 8800 for the OTN network. As is the case in KPN’s pan-European fiber-optic network, the Jiangsu links will be capable of carrying a mix of 100-Gbps and lower-rate wavelengths, Huawei says. The systems will support 100-Gbps over “hundreds of kilometers” without electrical regeneration, in Huawei’s words.

"The successful deployment of this 100G system with our strategic partner China Telecom has launched China into the ultra-broadband era," said Christian Chua, president of transport, Huawei. "100G is key to satisfying the growing demand for high-bandwidth services and enabling rapid telecommunications development to continue in China and around the world. We look forward to working with our global partners to continue providing high-quality, cost-effective solutions for the ultra-broadband era."

中国电信采用华为100Gbps DWDM系统，在南京和无锡之间开局，可实现100Gbps几百公里的无再生传输。

KPN International deploys Huawei’s coherent 100-Gbps WDM systemby Stephen Hardy
June 22, 2011

Huawei has joined the 100-Gbps deployment club. The Chinese systems house says that Dutch national carrier KPN has deployed Huawei’s coherent 100-Gbps technology on the KPN International pan-European WDM fiber-optic network.

Huawei says its coherent-enabled systems will allow KPN International to transmit 100-Gbps services alongside existing 10-Gbps and 40-Gbps traffic, which enables 100-Gbps wavelengths to be added to the network without disturbing lower-speed traffic. The system also support 100-Gbps transmission for 613 km without regeneration.

"KPN International is committed to providing users with reliable, fast and innovative services. The leading coherent 100G commercial application enables us to secure large bandwidth and high stability requirements on our network and serve our customers even better," said Jasper Snijder, managing director of KPN International. "Due to Huawei's leading WDM solutions, our international network remains at the cutting-edge providing high performance to accommodate fast-growing service demands."

Ciena (then Nortel) was the first company with a commercial 100-Gbps deployment; Verizon installed its equipment in a link connecting Paris and Frankfurt (see “Nortel unveils commercially available 100G optical system”). Alcatel-Lucent also has deployed equipment capable of transmitting 100-Gbps wavelengths (see "360networks goes 100 Gbps with Alcatel-Lucent" as an example).

华为可实现613 km 无再生传输100Gbps，同时在世界上开局的还有Ciena（原北电）和阿尔卡特。

Alcatel-Lucent rolls 400 Gbit router chip
Rick Merritt6/28/2011 4:00 AM EDT

SAN JOSE, Calif. – Alcatel-Lucent has designed a network processor capable of handling 400 Gbit/second data flows, twice the throughput of the best chip from archrival Cisco. The FP3 will appear in edge routers in mid-2012 and ultimately will spearhead the company's drive into core routers.

The chip is the latest volley in a long standing war among top routers makers including Ericsson, Huawei and Juniper. Each company develops its own network processors with competing Silicon Valley teams.

Cisco rolled out its 100-200 Gbit/s CRS-3 router chip in November. It is said to have a next-generation chip in the works called Pita with as many as 200 cores to handle 400 Gbit/s flows, and Huawei is working on a similar chip due next year.

"Alcatel-Lucent will have a clear advantage for now in throughput," said Shin Umeda, a vice president for router market research at Dell'Oro Group.

What's less clear is how the chips compare in their abilities to inspect and manage data flows for security and other functions. Umeda said Alca-Lu may have an edge because its new FP3 chip is a third-generation effort, and as such has a longer history than some competitors' offerings.

Cisco owns the edge and core router markets, but its share has been slipping in recent years. Cisco commanded 42 percent of the $5.9 billion edge router market last year, down from 57 percent in 2006, according to Dell'Oro. It had a 58 percent share of the $2.7 billion core router market last year, with Juniper in second place at 30 percent.

Alca-Lu and Juniper were nearly tied for second place in edge routers last year at 22 and 20 percent respectively. Alca-Lu does not currently have a core router offering, but is expected to design one around the new FP3 chip. Juniper announced its latest router chip in late 2009.

Inside the FP3

The FP3 consists of three chips made in 40nm technology, a 288-core packet processor, a traffic management chip and a fabric-access chip. Together the three can handle up to 400 Gbits/s of raw data flow with all inspection and management services enabled, consuming about 0.15 W/Gbit/s.

The cores used in the packet processor are based on the company's own proprietary design.

To support a variety of configurations, the chips are geared to use virtually any form of solid state memory including DDR1 or DDR3 DRAMs, QDR or T-CAMs. Alca-Lu worked with Micron, NetLogic and Samsung to make sure their chips were supported.

Alca-Lu believes it is unique in needing only one chip set per line card. Some competitors such as Juniper require two of their Trio chip sets on a single card, said Tom Jacobs, FP3 product manager at Alca-Lu. Such line cards require a more complex board design, have more points of failure, lower yields and draw more power, he said.

The FP3 chips will first appear by next June in three line cards for Alca-Lu's existing edge routers. One will support two 100 Gbit/s Ethernet ports, another will support six 40G Ethernet ports and the third will have 20 10G Ethernet ports.

The chips are already running on prototype line cards in the company's labs where they are undergoing testing.

With the FP3, Alca-Lu is getting out ahead of its carrier customers, none of whom have deployed 100 Gbit/s production networks yet, said Houman Modarres, a senior director of product marketing at Alca-Lu. As many as 14 of the company's customers have started some form of 100G trials, he added.

"They want systems with many more 10G line card interfaces, and we wanted to accelerate 100G adoption," said Modarres, explaining the leap to the 400G chip.

阿朗设计了一个可以处理400Gbps数据流的网络处理器FP3，2倍于思科CRS-3 路由芯片。在core router市场，第一位的Cisco占据了58%的份额，Juniper占了30%。在edge router市场，思科42%，阿朗和Juniper分别占了22%和20%。

FP3用40nm制造，每Gbps功耗0.15W。支持任意格式存储器，合作伙伴美光，Netlogic，三星。FP3会于明年6月应用在edge router的3个线卡上，一个支持2个100G 端口，另一个支持6个40G端口，最后一个支持20个10G端口。

Cisco cutting 10,000 jobs?by Stephen Hardy
July 12, 2011

Bloomberg, citing what its reporters called “two people familiar with the plans,” says that Cisco (NASDAQ:CSCO) could cut as many as 10,000 jobs through a combination of layoffs and buy-out packages (see Bloomberg’s story). Such a move would reduce Cisco’s workforce by 14%.

According to Bloomberg’s reporting, as many as 7,000 jobs could disappear by next month. An additional 3,000 positions would be eliminated through buyouts of employees who have accepted early retirement offers.

Cisco would not confirm Bloomberg’s figures.

As reported earlier, Cisco Chairman and CEO John Chambers and COO Gary Moore announced in May at the company’s third quarter earnings call that Cisco would trim its employee roster in hopes of saving $1 billion (see “Cisco: Layoffs are coming”). Moore said that the layoffs would include both full- and part-time positions and be global in scope.

In addition to the layoffs, Chambers also has embarked on a restructuring of the company to focus on areas of greatest opportunity. They include:

core routing, switching, and services
collaboration
data center virtualization and cloud
video
architectures for business transformation.- n7 i6 p9 a5 I. L7 b% S8 B

Therefore, it appears likely that many of the layoffs will come from activities outside of these areas, such as Cisco’s consumer operations.

Cisco is likely to reveal its workforce reduction plans during its fourth quarter fiscal 2011 earnings call. That quarter ends at the conclusion of this month, which would make the call sometime in August.

裁人的消息又来啦，这次是思科，准备裁掉10,000个职位，其中3000个名额是让其主动退休。不过据国内思科的朋友说，跟他们的关系不是太大就是。另外，钱伯斯说要重整业务，不知是不是应对 huawei 杀入企业网的举动。

Santur 10X10 MSA 100-Gbps CFP optical modules now generally availableby Stephen Hardy
July 19, 2011

Santur announced the general availability of its 100-Gbps CFP optical modules compliant with 10X10 Multi-Source Agreement (MSA). The 10X10 MSA, driven largely by Google, aims to create a lower-cost, more easily developed alternative to the IEEE’s 100GBase-LR4 optical module for singlemode high-end data center applications (see “Google joins tech vendors in 10x10G 100 Gbps optical transceiver multi-source agreement”).

As called out in the 10X10 MSA, the CFP module supports 2-km reach over singlemode fiber, placing it between the 100-m multimode 100GBase-SR10 and 10-km 100GBase-LR4. Because it does not use the 25-Gbps optics or electronics of the latter module, the 10X10 MSA device offers lower cost and obviates the need for such components as gearbox ICs, Santur points out. As a result, Santur says that it will offer volume production pricing of less than $5,000 for 100 units or more. The devices also will feature a maximum power dissipation of 13 W.

Santur says it has leveraged its expertise in creating array-based tunable lasers in creating the new optical module. “For more than 20 years, we have been discussing the possibility of integrating multiple active optical components on a single chip to reduce cost and power. Over time, several companies have tried but none offered such high level of integration that allowed us to meet our cost and power targets,” said Paul Meissner, oresident and CEO of Santur. “The hybrid integration platform scales to higher data rates and wider WDM lanes to create many product variants based on a common architecture targeted at cost effectively meeting the needs to expand the global Internet infrastructure.”

While other module vendors have expressed support for the 10X10 MSA, including JDSU, Oplink, and Source Photonics, Santur is the first such supplier to offer the module in volume. (For more on 10X10 MSA module sourcing, see “The 10X10 MSA conundrum.”)

定位2km的10x10 MSA还是很有生命力的。

Maxis, Alcatel-Lucent bring 100 Gbps to Malaysiaby Stephen Hardy
August 10, 2011

Maxis Berhad, an integrated communications service provider in Malaysia, has deployed coherent 100-Gbps technology from Alcatel-Lucent (Euronext and NYSE:ALU) in its core optical backbone network. Maxis will leverage the upgraded capabilities to support both fixed and mobile Internet service, business services, cloud computing, and machine-to-machine communications.

The fiber-optic network is the first commercial deployment of 100-Gbps single-carrier DP-QPSK technology in Asia-Pacific, Alcatel-Lucent asserts.

Maxis’s fiber-optic network includes more than 10,000 km of fiber infrastructure within Peninsular Malaysia. The infrastructure construction included fiber sharing and swapping and has a fiber to the premises (FTTP) component.

In addition to the high data rates, Alcatel-Lucent’s 100G coherent optical network equipment will offer faster service provision and shorten time to market for new services, the systems house asserts.

“Maxis's growth and track record have been supported by a strong commitment to bringing innovation and transforming our architecture to address the challenges of capacity, network protection and quick provisioning,” said Mark Dioguardi, Maxis’s CTO. “The deployment of this optical network solution transforms our core transmission network; much like upgrading from a normal trunk road to a super highway, allowing users to enjoy faster and seamless high-capacity connectivity within Peninsular Malaysia.”
