WTD launches new products at OFC/NFOEC

MARCH 21, 2007 -- Wuhan Telecommunication Devices Co., Ltd. (search for Wuhan Telecommunication Devices) has announced new an XMD 10-Gbit/sec transmitter optical sub-assembly (search for TOSA) & receiver optical sub-assembly (search for ROSA) and a 10-Gbit/sec tunable optical transponder, both of which be highlighted at next week's OFC/NFOEC Conference in Anaheim, CA.

The XMD 10-Gbit/sec TOSA features an uncooled DFB laser diode with MQW structure, built-in InGaAs monitor photodiode, and FPC for RF output. It also features a TO-56 packaged.

The XMD 10-Gbit/sec ROSA features a planar InGaAs PIN photodiode, LC package, and FPC for RF output. Its operating temperature range is -40 ∼ 85 ° C.

The 10-Gbit/sec tunable optical transponder is available in 800-km reaches and features a Mach-Zehner Lithium Niobate (LiNbO3) external modulator integrated with 16 channels of 622-Mbit/sec mux and demux and an I²C interface to provide monitor control and alarm. Wuhan says its 10-Gbit/sec tunable optical transponder covers the full C and L bands, making it ideal for dynamic wavelength provisioning in ROADM applications. It meets Telcordia GR-253 and OIF SFI-4 requirements and targets the SONET/SDH and 10-Gigabit Ethernet, metro/regional/long haul DWDM markets.

WTD plans to display the new products mentioned above with its 10-Gbit/sec tunable transponder, 40- and 80-km DWDM XFP transceiver, and 4-Gbit/sec Fibre Channel SFP transceiver in its booth (#1421) next week at OFC/NFOEC 2007.
