CyOptics launches 10Gb/s CWDM TOSAs in support of 40GbE standard

CyOptics Inc of Lehigh Valley, PA, USA, which designs and fabricates InP-based optical chips and components, is expanding its 10Gb/s TOSA (transmit optical sub-assembly) portfolio by making available samples of coarse wavelength division multiplexing (CWDM) TOSAs for the emerging 40GBASE-LR4 standard. Full production will ramp up in second-quarter 2009.

The new 10Gb/s TOSAs (TX1270, TX1290, TX1310, TX1330) operate on the ITU-T CWDM grid of 1271, 1291, 1311 and 1331nm, and meet the emerging 40 Gigabit Ethernet (GbE) requirements for 40GBASE-LR4 standardized by the IEEE 802.3ba Task Force in support of 10km transmission over single-mode fiber.

The TOSAs are based on CyOptics’ standard field-proven buried hetero-structure distributed feedback (DFB) laser chip design, with over 2.5 million units shipped since 2005 and more than 24 billion field service hours. The TOSAs incorporate an integrated InGaAsP monitor photodiode and are packaged in a TO-header with receptacle, compatible with the 10Gb/s XMD multi-source agreement (MSA), for uncooled use over an operating temperature range of -5ºC to +75ºC and transmission rates of up to 10.7Gb/s.

“The emerging 4x10GbE standard for the 10km interface is the fastest solution to market and uses cost-effective off-the-shelf optical and IC components,” says Kou-Wei Wang, VP and general manager of CyOptics’ InP OEM business. “Our new TOSAs leverage CyOptics’ technology from the rapidly growing FTTx market to enable next-generation 40G Ethernet solutions.”

The introduction of these new products enhances CyOptics’ 10Gb/s product portfolio of DFB, Fabry-Perot (FP) and electro-absorption modulated laser (EML)-based TOSAs as well as PIN and avalanche photodiode (APD)-based ROSAs (receive optical sub-assemblies).
