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.

ClariPhy samples 40G coherent chip
% k  ~* [& L, z- S- U3 [2 Q- NRick 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.

PMC-Sierra (NASDAQMCS) 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.
- G* V1 P- b6 N
3 N$ t& p# z  q1 r2 F& ^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.

' N" M+ x/ p) H3 ^) `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.

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.

AMCC uses 25G signals to hit 100G
' a( `4 |! m5 e# q7 z0 LRick 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.# Q$ t: P# [8 S  s
The S28010
' d+ u" M# p' C' ? 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.! T5 B5 M4 e; K
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.
2 i, O" g- m# [$ Z6 V8 C, G3 LExisting 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 $750 when it samples in September.
2 A, q1 \! \0 L$ l! T& aThe 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.& N. ^, @+ S4 O2 D; N$ ]/ i
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.
8 M, e/ a7 M; U* M% e+ LThe 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.9 O) u9 H; w$ g& C" X: A' M
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.

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.

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.

Alcatel-Lucent rolls 400 Gbit router chip
/ Y1 m- i- \6 {( Q& F0 `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.

7 S- g+ K' v# h) N; P( d3 LWhat'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
" j% ?" g+ |; t4 o4 O8 L$ L3 t: t
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.

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).

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”).

Santur 10X10 MSA 100-Gbps CFP optical modules now generally availableby Stephen Hardy0 \# M; Q1 B9 [2 B$ Z

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”). # Y+ [( ^- [4 R) x- f, j; S

& o$ h) C: _  L) KAs 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.
# |, E! n; W  s4 Z* Q
$ a! I5 E+ W  l% ~  k0 lSantur 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.”
3 O( R  l$ c/ B" p/ X" M( l- R5 Y9 |$ E! `  H
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.”)

据奥特斯CEO葛思迈(Andreas Gesternmayer)透露，“至今为止，奥特斯在中国市场的总投资为7亿美元。我们刚刚完成了上海工厂最后一条产线的投产，重庆工厂也已启动土建，进展顺利。2011年7月底，上海工厂产能实现全部满载。新增的3条生产线分别在今年5月和8月投产，再次印证了高端PCB产品的井喷增长和需求。总体来讲，上海工厂产能共提升30%达到年产量71万平米(技术上最大产能)。”由于上海的工厂的土地储备和生产能力已经完全用尽，奥特斯在中国的西部城市重庆建立了新的制造基地，以满足不断增长的市场需求。葛思迈表示，“今年投资的重庆新工厂，将分为三期进行建设，共占地125,000平方米，于2013年启动生产。目前，第一期建设已于2011年6月动工，进展顺利，我们将根据客户需求和新技术所需安装基础设施和设备。”虽然投资于西部城市，但是从工厂的设备技术含量到生产的产品都与上海工厂没有什么区别，可以看出并不是为了寻找更低的成本而在中西部设厂的代工企业的做法。5 k: D$ |$ @" @1 I. ], j0 i& T; r

据国际电联称，中国和印度有力推动了移动设备的发展。同时，中国国家统计局2011年2月数据也显示，截止至2010年12月，中国已经拥有8.5亿手机用户，占总人口的64%；其中，3G手机用户为4700万人。作为移动消费市场的中心，中国在奥特斯全球市场中扮演着越来越重要的角色，其中移动设备业务的年收益中有超过60%来自中国。由于整个中国在移动设备供应链当中的重要地位，奥特斯决定将其移动设备事业部总部迁移到中国上海，这一举措不仅表明了对亚洲市场充满信心，更反映出奥特斯已经成为移动设备市场中重要的供应商。

除了增长迅速的消费电子市场，奥特斯的高端PCB产品还大量应用在汽车电子和工业电子领域，这几个领域都对PCB本身的技术升级有非常大的渴求，如何增加PCB的密度以及降低PCB的厚度是每个PCB厂商日思夜想的事情。在技术创新方面，奥特斯引进的元件埋嵌封装专利ECP技术高效地将主动与被动元件集成于印刷线路板，适用于那些要求体积尽可能小、功能尽可能多的电子产品。传统概念的电子产品是将封装后的半导体芯片加载到PCB上，而ECP技术则在现有的封装方式外提供了另一种选择，由此这家PCB公司甚至可以进入封装领域。葛思迈在回应记者关于封装测试企业有可能向下游整合PCB业务的问题时，说道：“其实技术的发展让我们有机会进入到封装市场。”SiB(System in Board)和SiP(System in Package)这两个概念由于技术的发展而逐渐走向了融合。由于高端PCB上的线宽越来越小，高端PCB生产商的生产工艺越来越接近于芯片生产商，可以在奥特斯的工厂里看到很多光刻机，恍然置身于晶圆制造厂一般。

LeCroy has announced the LabMaster 10 Zi-A (LM10Zi-A), a physically large modular scope system that acquires 80G samples/sec/channel and can deliver 36-GHz bandwidth on four to 20 channels. Thanks to patented frequency-domain-based DBI (digital-bandwidth-interleaving) technology, it can acquire 160G samples/sec/active channel and deliver 60-GHz real-time bandwidth on two to 10 channels. Bandwidth greater than 33 GHz has previously been available only from sequential-equivalent-time-sampling scopes, which, though highly accurate, don't well suit many multigigahertz-scope measurements that signal-integrity engineers and high-speed-optical-communication-network designers make.* f) E& S% ?! B' H2 f

The company adopted the modular approach for several reasons. For example, few probes have bandwidths greater than approximately 30 GHz. This lack often necessitates the use of pairs of channels as differential inputs for capturing signals that contain significant energy at and above 30 GHz. As a result, in applications that require simultaneous acquisition and display of multiple wideband signals, scopes that provide more than 30-GHz bandwidth on just two channels often prove to be inadequate, because they become, in effect, single-channel instruments. According to Ken Johnson, LeCroy's marketing director for high-performance scopes, the lifetime in the market of a scope that offers 30-GHz or higher bandwidth on only two channels would be too short to justify its development cost. LeCroy's modular scope-system architecture yields products with greater expected market lifetimes. Customers can upgrade their systems as their needs dictate and can continue using-as parts of their upgraded systems-components they purchased earlier. Although most modern, ultra-high-performance scopes are upgradeable, the upgrades are neither as complete nor as cost-effective as those of modular scope systems. Johnson says that, over a period of five years or more, LeCroy customers will be able to repeatedly upgrade their modular scope systems without discarding any of the older components. Thus, in the ultra-high-performance range, even if the sole criterion were economics-and it isn't-the modular architecture would soundly beat a fixed-configuration box.0 F- ?* `: E( n8 e$ x

In systems that include several acquisition modules, those modules can be identical or of multiple types. The display is a 15.4-in.-diagonal, 12803768-pixel, color LCD, which provides significantly greater viewing area than do the 12.1-in. LCDs that are common in high-performance DSOs. The LM10Zi-A series includes five models of acquisition modules, two of which support DBI. The module sizes come close to the industry-standard multiples of 1.75-in. height and nominal 19-in. width. The display/control module measures approximately 10.5 in. high, and most of the acquisition modules measure approximately 7 in. high. Prices for complete working systems begin at $252,900, which buys a four-channel system that acquires 80G samples/sec on all channels and delivers 25-GHz bandwidth on each. For $411,900, you can buy a system that takes 80G samples/sec on four channels and delivers 36-GHz bandwidth on each or takes 160G samples/sec on two channels and delivers 60-GHz bandwidth on each. You can equip the system with 1.024G points/channel of DBI-mode acquisition memory; 40M points/channel in DBI mode are standard.( o: x, o7 q% p8 [3 r) ^" Q/ }# t

Agilent Technologies Inc. (NYSE: A) today introduced a 60-GHz remote sampling head oscilloscope module for engineers who design, validate and manufacture high-speed electrical communications systems and components.& ~( c  P# o$ p- J2 h( D4 k

. h% H$ l' @$ ~The Agilent N1045A 2/4-port electrical remote sampling head module provides the most economical solution for accurately characterizing multilane designs used in today's new and emerging standards such as IEEE 802.3 ba/bj/bm (40Gb/100Gb Ethernet) and Optical Internetworking Forum CEI 3.0.: G( I3 b$ \7 v.

The popularity of smartphones, tablets and online video content continues to drive the need for faster network connections. Increased network performance is enabled through multiport serial interfaces operating at 28 Gb/s and up. Until now, testing high-speed, high-port-density components and systems required an expensive configuration of multiple oscilloscopes and complicated switching that compromised signal integrity.

By combining the N1045A with the 86107A precision timebase module, users can create an eight-channel 60-GHz system with an ultralow 200-fs rms timebase jitter. This is ideal for efficiently testing a quad differential port device operating at 25 to 28 Gbps.5 c) w7 w  C5 T/ G

, f9 O) e4 Z; nEach low-noise sampler is located at the end of a flexible 1.6-meter cable to minimize cable loss and ensure the highest signal fidelity. With a selection of bandwidth settings (60, 45, 35 or 20 GHz) and independent sampler skew control, the N1045A allows users to optimize the receiver for the device under test. The industry's lightest and smallest remote heads allow the samplers to be positioned in very tight locations. To minimize the use of adapters, the modules can be configured with 1.85-mm male or female connectors.
