Fujitsu Quantum Devices Ltd. and Sumitomo Electric Industries Ltd. announced enhancements to their multi-source agreement (MSA) for a 10-Gbit/sec transmission laser diode (LD) module.
The MSA, which was originally announced in March 2002, defines a standard for 1.55-micron wavelength distributed feedback LD monolithically integrated with an electro-absorption modulator mounted onto what the companies claim is the industry's smallest-in-class metal ceramic package. The LD also includes a driver IC and transmits data at speeds of 10 Gbits/sec in compliance with ITU-T G.691 and Telecodia GR-253-CORE. In response to growing requests from the customers, the MSA specifications were defined in further detail and new product types, including direct modulation type, have been added to increase the ease of use for designers of system equipment and optical transceivers and transponders.
In addition, NEC Compound Semiconductor Devices Ltd., NTT Electronics Corp., and Samsung Electronics Co. Ltd have joined the MSA. The growing number of supporters of the MSA ensures stable availability of compatible products to the customers.
The module will be displayed in the exhibition booths of SEI and NEC Compound Semiconductor Devices at ECOC 2002, in Copenhagen, Denmark, September 8-12, 2002.
