CyOptics launches low-cost 1310nm FP & DFB TOSAs for 10Gb/s enterprise applications

Indium phosphide-based optical chip and component maker CyOptics Inc of Lehigh Valley, PA, USA has made available sample quantities of its new 1310nm Fabry-Perot (FP) and distributed feedback (DFB) transmit optical sub-assemblies (TOSAs) for 10Gb/s applications. Volume production will begin in December.

The lasers are designed as a ridge waveguide structure and contain InAlGaAs-based multi-quantum well (MQW) active layers for improved static and dynamic performance over temperature. The TOSA products incorporate an integrated InGaAsP monitor photodiode and are packaged in a TO header with receptacle for uncooled use over an operating temperature range of -25°C to 90°C and for transmission rates of up to 10.7Gb/s.

The TX299K (FP) and TX293K (DFB) TOSAs are compatible with the 10Gb/s miniature device (XMD) multi-source agreement (MSA) for high-performance transceivers addressing the OC-192/STM-64 SONET/SDH, LRM 10 Gigabit Ethernet and 8x Fibre Channel market applications.

The launch of the FP and DFB TOSA’s completes CyOptics’ 10Gb/s product portfolio, which already includes higher-performance uncooled 1.3 micron EML (electro-absorbtive laser) TOSAs and 1.5 micron EML TOSAs with thermo-electric coolers (TECs) in support of 40km, 80km and DWDM 10Gb/s applications, as well as PIN and APD (avalanche photodiode) ROSAs (receive optical sub-assemblies). The InP laser and detector chips are manufactured in CyOptics’ fab in Breinigsville, PA; the cylindrical TO cans and TOSAs are manufactured by CyOptics’ packaging partners in Asia.

“With the addition of these low-cost solutions, we have one of the industry’s broadest 10Gb/s TOSA product offerings,” claims Kou-Wei Wang, VP and general manager of CyOptics’ InP OEM business.
