Avago 16 Gigabit Fibre Channel transceiver now in production

by Lightwave Staff
August 16, 2011

Avago Technologies (Nasdaq:AVGO) says its new AFBR-57F5PZ SFP+ transceivers for 16 Gigabit Fibre Channel applications have reached production status. The transceivers support industry-standard signaling rates up to 14.025 GBd.

Avago expects the modules to find application in switches, routers, host bus adapters, RAID controllers, tape drives, and video switching, as well as inter-switch and inter-chassis aggregated links.

While the AFBR-57F5PZ SFP+ transceiver offers twice the capacity of 8 Gigabit Fibre Channel devices, it operates at “essentially” the same power level, Avago asserts. The SFP+ module’s transmitter and receiver can operate at different data rates, as is often required during Fibre Channel speed negotiation. The module maintains compatibility with legacy 8 Gigabit and 4 Gigabit Fibre Channel devices as well, Avago says.

Avago also touts the following additional features:

Operating temperature range of 0° to 70° C and supply voltage of 3.3 V ± 5%
Lead-free and RoHS-compliant
Digital diagnostic features per SFF-8472
LC Duplex optical connector interface conforming to ANSI TIA/EIA604-10 (FOCIS 10A)
Enhanced EMI performance for high port density applications.
The AFBR-57F5PZ transceiver incorporates Avago’s 850-nm vertical-cavity surface-emitting laser (VCSEL) and PIN detector technology. This combination ensures that the multi-rate SFP+ module is compliant with FC-PI-5 and 16G/8G/4G Fibre Channel specifications, the company states. The module will respond to both rate select pin and control bit inputs, which simplifies Fibre Channel host auto-negotiation algorithms, layout, and software, Avago adds.

The AFBR-57F5PZ 16 Gigabit Fibre Channel transceiver is priced at $215.35 each in 100-piece quantities. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.

by Stephen Hardy
August 30, 2011

Gigalight says it has commercialized 40-Gbps QSFP+ active optical cable (AOC) components, which it asserts is a first for a company based in China.

The 4x10-Gbps QSFP+ AOC features a pair of QSFP+ optical transceivers connected with ribbon OM3 multimode fiber cable. The 40G parallel optical module leverages four 850-nm VCSELs and four PIN receivers, each operating at 10 Gbps. Such AOCs are used in supercomputer and SDR, DDR, and QDR InfiniBand applications.

Gigalight says the 40G QSFP+ AOC is the result of an eight-month development effort, with design of the four-channel VCSEL array and matching PIN array a major focus. High-level circuit, software, and structure design, as well as the production of passive optical devices, were among the core competencies used. Gigalight also used its proprietary FA coupling technology and Xili semiconductor-based optical waveguide product line.

The company says the parallel optical transceiver platform can be expanded for greater transmission capacity, including 12x10-Gbps. Gigalight says it will apply the lessons learned to the production of 100G CFP-SR10 devices.

Gigalight will display QSFP+ and CXP AOCs together with high-speed error detection instruments at the upcoming CIOE show, September 6-9 in Shenzhen.

易飞扬发布了40G QSFP+ AOC 模块，可以用于各种速率的InfiniBand，并宣称是国内首家推出这一模块的厂商，将在9月6～9日在会展中心举行的CIOE 上展出。

IEEE P802.3bj Task Force targets 100 Gigabit Ethernet for copper, backplanes

by Lightwave Staff
September 26, 2011

The IEEE has announced that the IEEE P802.3bj Task Force will work to develop specifications for 100-Gigabit Ethernet transmission over backplanes and short-reach copper assemblies. The new specifications will extend those already created for IEEE Std 802.3ba-2010.

“From the challenges of ever-increasing front-panel capacities to continuing advances in processors, high-performance computing, and server virtualization technologies, the ability of systems to meet spiraling bandwidth demands remains challenging,” said John D’Ambrosia, chair, IEEE P802.3bj Task Force and chief Ethernet evangelist, CTO Office, Dell. “By expanding on the solid foundational standards work already completed, IEEE P802.3bj will provide better options for system designers to minimize or eliminate the bandwidth bottlenecks facing end-users.”

The P802.3bj Task Force will focus on four-lane, 25-Gbps electrical signaling architectures that will support 100-Gbps Ethernet operation across backplanes up to 1 meter in length and copper cable operations up to at least 5 meters. The IEEE P802.3bj Task force also will seek maximum compliance and compatibility with other IEEE 802.3 installations.

The copper applications likely will include intra- and inter-rack connections via twinaxial copper cables. The new specifications are expected to benefit blade servers and data centers.

“The industry and users alike are looking for creative, forward-looking solutions that will allow them to leverage today’s technology innovations, such as 100-Gbps Ethernet,” said David Law, chair, IEEE 802.3 Working Group and distinguished engineer, HP Networking. “As the capabilities of 100-Gbps Ethernet are enhanced with IEEE P802.3bj, the resources, expertise and leadership that are the hallmarks of IEEE will support the continuing evolution of Ethernet to higher speeds and capabilities.”

简而言之，这是100G Ethernet 的背板规范，将规定25Gx4，在背板上传输1米，40 英寸。是802.3ba的延续，802.3ba只规定了点接口速率为10Gx10,光接口速率25Gx4。

Alcatel-Lucent adds Rostelecom to 100-Gbps coherent customer list

by Lightwave Staff
October 4, 2011

Alcatel-Lucent (Euronext Paris and NYSE: ALU) says that OJSC Rostelecom, Russia’s largest telecommunications company, to upgrade its backbone network with 100-Gbps transmission capabilities. The link, which connects Europe through Russia to the Middle East, will cover 3,500 km on Rostelecom’s ‘North-South Transit’ route.

Rostelecom will deploy Alcatel-Lucent’s 1830 Photonic Service Switch (PSS), which supports Optical Transport Network (OTN) and WDM technology on a single platform to simplify operations and cuts costs. Use of the 1830 PSS will enable Rostelecom to support a mixture of 10G, 40G, and 100G channels on the same fiber pair, which means it can reuse its existing optical infrastructure and then upgrade and expand capacity on the network as needed, according to the systems supplier.

Ivan Zima, executive director of communication networks planning and development of Rostelecom, said, “To grow our business in line with the market demand for communications services, we need to cost-efficiently increase the capacity and throughput of our key backbone routes. Proactive investments in the development of our optical transport network will improve its performance and flexibility and enable us to address the rapid growth in demand for high speed data transmission.”

美国电子行业信息咨询公司Prismark公司的分析报告指出，2010年至2015年间，中国将以近10%的复合年均增长率成为全球发展最快的PCB市场。至2015年，中国市场的HDI PCB产出所占比重将由如今的42%提升为50%。今年5月，奥特斯科技与系统技术股份公司(AT&S)宣布其市场策略，将提高在中国的产能和市场占有率，以满足因为智能手机和平板电脑市场高速增长而带来的全球对于高端印制电路板(PCB)的产品需求。根据该公司2011/12年度的第二季度财务报告：AT&S第二季度的销售额达到1.314亿欧元，营业利润1500万欧元，创史上最好水平。值得一提的是，60%的第二季度总收益都来自中国市场。
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。

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。

近来由于欧债危机严重，全球经济前景不容乐观，对此葛思迈表示，“鉴于当前的宏观环境，HDI产品需求增长的前景不甚明朗，很难做出季度预测。但是，市场基本面不会有变化，也显示了较有吸引力的中期增长率。假如消费者的支出保持在现有水平不变、汇率变化不增加，以及欧美经济不出现如2008年一样的突然大幅下滑，我们还可以做出一些短期展望。不管怎样，圣诞假期和消费者行为将对市场业绩产生重要影响。”

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.

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.

An LM10Zi-A system comprises a display/control module and from one to five acquisition modules. 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.

The system uses LeCroy's proprietary new Si-Ge (silicon-germanium) chip set, which is fabricated with IBM Corp's (www.ibm.com) 8HP manufacturing process. This process yields analog ICs with greater speed and lower noise than do older Si-Ge processes, which, themselves, represented major advances over purely silicon processes.

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.

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.

Users can configure up to four N1045A modules in a single Agilent 86100D DCA-X wide-bandwidth oscilloscope mainframe to create a system with 16 channels.

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.

But the 86100D DCA-X mainframe, configured with one to four N1045A modules, provides a 2- to 16-electrical-channel measurement system that is both economical and accurate. 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.

Each 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.

"Today's engineers are tasked with creating devices that are twice as fast as previous designs and less expensive to build," said Jay Alexander, vice president and general manager of Agilent's Oscilloscope Products Division. "Test equipment that provides the necessary accuracy to validate next-generation designs while enabling lower costs is essential. The 86100D's channel density can increase throughput and lower capital costs, resulting in a dramatic reduction in the cost of testing while simultaneously improving measurement quality."

The Agilent N1045A 60-GHz 2/4-port electrical remote sampling head module can be ordered now, with prices starting at $43,000.

早在2010年Agilent推出DCA-X时，就宣布支持16通道，时隔2年之后，这个预告终于成现实啦，这个等待比丫的越狱还要长一些，但总算来啦。推出这个模块，可以完美的支持现在100G或400G的应用，不错。

插入16通道后的示波器还是相当壮观的
