Quality of service is key to Gigabit Ethernet ICs
The MVTX2800 family of Gigabit Ethernet switching ICs from Zarlink Semiconductor deliver full-wire speed forwarding and leading quality of service features to metropolitan optical access equipment.
By combining four ultra-high-capacity, independent fibre transmit and receive channels into one integrated module, Zarlink's QSFP product provides InfiniBand equipment manufacturers with edge and board density savings of greater than 60% while slashing power consumption to 250mW per transceiver channel.
The QSFP module also integrates comprehensive digital diagnostic monitoring.
Zarlink is developing a complete QSFP product family that will extend these performance and design benefits to other applications, such as the Gigabit Ethernet and storage markets.

"The InfiniBand QSFP transceiver responds to the market need for a reliable, high-density, 1W power dissipation, hot-pluggable, scalable data-rate, multi-lane networking and data centre optical link", said Dr Marco Ghisoni, QSFP Product Manager, Zarlink Optical Solutions.
"Building on Zarlink's market-proven expertise in developing fully-qualified multi-channel parallel optical modules, VCSELs and optical IC technologies, and employing multimode fibre ribbon, the InfiniBand QSFP family will play an important role in high-density bandwidth-intensive applications, up to 40Gbit/s".
"The growing demand for bandwidth, longer link distances for optimum data centre configuration and InfiniBand port scalability requires new PHY layer media interconnect solutions", said Lloyd Dickman, Chief Technical Officer, System Interconnect Group, QLogic.
"Zarlink's dense pluggable optics solution, like its QSFP module demonstrated with our high-performance InfiniBand adapter, is an excellent example and the first of many new optical products that enrich the flexibility and scalability of InfiniBand deployment".
Zarlink's QSFP module follows the mechanical form-factor, electrical pin-out and diagnostic management interface specifications outlined in the QSFP MSA rev0.9x.
Zarlink is one of 21 member companies involved in defining the QSFP MSA.
"Zarlink has been one of the main contributors to the QSFP MSA, so it's no surprise that they were the first to release a module that supports the specification", said Scott Kipp, Chair of the QSFP MSA.
"At 5Gbit/s on each of the eight fibres, the Zarlink module offers the densest, pluggable transceiver bandwidth on the market".
Zarlink is now sampling 4x2.5 and 4x5Gbit/s InfiniBand QSFPs, supported by evaluation boards and a graphical user diagnostic interface.
Preproduction parts will be available in early 2007, with full production parts released by mid-2007.
Zarlink's complete range of QSFP modules is planned for production over the next 12 months.
