Emcore enters long-reach DWDM market with 10G XFP module

At this week’s 2007 Optical Fiber Conference (OFC) in Anaheim, CA, USA, Emcore Corp of Albuquerque, NM, USA announced samples of its new EDW-9100-XFP 1550nm dense wavelength division multiplexing (DWDM) long-reach XFP optical transceiver module, suited to applications including SDH STM-64, SONET OC-192 LR-2, and 10 Gigabit Ethernet (10GBASE-ZR).

Designed for greater-than-80km applications for the wide-area network (WAN) and long-haul markets, the module marks the expansion of Emcore’s portfolio from parallel short-reach and coarse wavelength division multiplexing (CWDM) interconnect products (parallel VCSEL and LX4 optical modules for the 300m multimode market) into DWDM and long-reach 10Gbps applications, says Clay Hudgins, 10G Module Product Line Manager at Emcore’s Fiber Optics Division. The 80km DWDM segment has been experiencing double-digit quarter-on-quarter growth, the firm says.

The product exploits the 1550nm technology of Emcore’s Ortel division, while maintaining a robust multisourcing strategy, Hudgins adds. The transceiver module consists of a transmitter with a cooled externally modulated laser (EML) emitting at a wavelength of 1550nm and a high-sensitivity receiver with an avalanche photodiode (APD) detector. Options include C-band and L-band coverage at 100GHz ITU-grid spacing. The C-band version is sampling now to Emcore’s key accounts; an L-band version will begin sampling in Q2/2007.
