Broadcom intros 100GbE multi-rate gearbox PHYs
Broadcom Corp. (NASDAQ: BRCM) has unveiled what it claims are the industry's lowest power and highest performance multi-rate 100 Gigabit Ethernet (GbE) physical layer transceivers (PHYs) for next-generation data center, enterprise, and core network equipment. The company also says that the new Broadcom BCM84790 and BCM84793 gearbox PHYs are the first multi-rate interfaces for 4-lane (4x25-Gbps) and 10-lane (10x10-Gbps) bi-directional transmissions.The new chips extend Broadcom's portfolio of 10GbE, 40GbE, and now 100GbE physical layer devices. The company joins a small club of vendors offering 100GbE gearbox PHYs, which also includes Inphi Corp. and Semtech Corp. (see “Inphi sampling CMOS 100-Gigabit Ethernet PHYs” and “Semtech ships 100G CFP Gearbox IC platform”).The BCM84790 and BCM84793 gearbox PHYs have the ability to multiplex and demultiplex data across four 25-Gbps channels to (or from) ten 10-Gbps channels. Both devices can be configured to support four bi-directional lanes at 10 Gbps for 40GbE repeater applications, support Ethernet and optical transport networking, and are compliant with the IEEE 802.3ba standard for 100GbE and ITU OTL 4.4 signaling.The BCM84790 features a 17x17-mm BGA package engineered to support CFP network applications; while the BCM84793 comes in a 19x19-mm BGA package with the ability to support 10-lane bi-directional transmissions at 10-Gbps per lane. This added flexibility ensures support for future-generation networking formats such as CFP2 and CXP, Broadcom adds.Built in low power 40-nm CMOS architecture, the new chips dissipate 2.5 W per port, delivering power savings of more than 35 percent compared to previously available parts, the company asserts.Key features: Supports Ethernet and optical transport networking (OTN) 100GbE/OTN VSR28 to CAUI interface Less than 200 fs root mean square (rms) of random jitter on the 25-Gbps transmit outputs High-speed eye monitoring diagnostics on all data I/O Integrated clean-up phase lock loop (PLL) reduces bill of material cost Single REFCLK (reference clock) input Low-latency architecture The BCM84790 and BCM84793 are sampling now. Production release is scheduled for the second half of 2012.
QualiSystems accelerates cloud infrastructure testing
QualiSystems has introduced the TestShell enterprise software framework’s compatibility for advanced testing of the cloud infrastructure, covering lab management, device provisioning, and test automation. Using TestShell, cloud testers can accelerate automation and simplify the time-consuming and complex task of mimicking cloud infrastructure in the lab to assure performance and bring new services rapidly to market.TestShellis designed to enable network, storage, and test engineers to easily adapt to the dynamic cloud-computing testing environment. By offering a holistic approach that requires no programming skills, it is simpler and quicker for cloud architecture, designers, and testers to accomplish set-up and testing of the infrastructure, QualiSystems says. The different cloud components that must interoperate – computing, services, storage, and networking – are tested individually and in concert to assure performance, stability, security, QoE, and QoS using TestShell.With a flowchart-based test editor, TestShell offers cloud testers the ability to automate a large range of test scenarios to simulate multiple iterations and massive network traffic by a large number of users prior to deployment. The framework simplifies management of the cloud testing environment through vendor-agnostic integration and central control of all test equipment, devices, and technologies, such as FC/FCoE switches, storage servers, virtualized machines, 40/100-Gbps ports, management/monitoring software, and more. Use of network equipment is measured and increased by enabling sharing capabilities between users and across sites.“With a drastically more complex environment that relies on combining several emerging technologies, cloud testers face growing challenges ranging from the required technical knowledge to the large integration spectrum essential for testing,” said Eitan Lavie, vice president of product and marketing at QualiSystems. “One of TestShell’s key strengths is its ability to provide a holistic approach for management and automation of the cloud-testing environment thereby alleviating the pain point for the testers behind the cloud.”QualiSystems says a number of leading vendors are already using the TestShell framework for test and lab automation in the cloud, data center, and network infrastructure.
Infonetics pegs optical transceiver sales at $3.3 billion in 2016
Growth in 100-Gbps, tunable, and SFP+ optical modules points toward an overall expansion of the optical transceiver market, according to Infonetics Research. The market research firm expects the optical transceiver market to be worth $3.3 billion, according to its newly released 10G/40G/100G Optical Transceivers Market Size and Forecast.The report tracks 10-Gbps, 40-Gbps, and 100-Gbps optical transceivers and transponders for optical transport, enterprise, and carrier routing and switching applications."2012 will be a pivotal year for 100G design activity, with many new equipment vendors fielding production equipment," says Andrew Schmitt, principal analyst for optical at Infonetics Research. "This will drive volume in the component world in 2013 as carriers reboot their optical networks and roll out all-coherent networks. In the meantime, 10G WDM interface growth continues with the tunable XFP playing the lead role, while 10G SFP+ volumes in the data center explode."Some of these trends have already started. For example, unit shipments of 10-Gbps SFP+ optical transceivers nearly doubled in 2011 versus 2010, according to the report. Infonetics expects demand for SFP+ modules will grow at a 40% compound annual growth rate through 2016.Meanwhile, tunable XFP shipments nearly tripled in 2011 as several new suppliers entered the market. Unit shipments of WDM-capable modules grew 24% in 2011 over 2010 as well.
