Six companies join DWDM Pluggable Transceiver multi-source agreement
October 3, 2002--Agilent Technologies Inc., Nortel Networks, and Agere Systems have announced that Alcatel Optronics, JDS Uniphase, Mitsubishi Electric, NEC Corp., Oki Electric, and Sumitomo/Excelight have joined the DWDM Pluggable Transceiver multi-source agreement (MSA) and will supply devices that conform to the specification defined by the MSA.
Agilent Technologies Inc., Nortel Networks, and Agere Systems have announced that Alcatel Optronics, JDS Uniphase, Mitsubishi Electric, NEC Corp., Oki Electric, and Sumitomo/Excelight have joined the DWDM Pluggable Transceiver multi-source agreement (MSA) and will supply devices that conform to the specification defined by the MSA. Transceivers developed using this new specification are designed to help improve network planning, commissioning, and maintenance of optical networks and reduce system downtime and inventory costs.
The DWDM Pluggable Transceiver MSA announced by Agilent, Nortel Networks, and Agere Systems in June 2002 establishes a standard that specifies uniformity for 2.5-Gbit/sec (OC-48) DWDM pluggable transceiver package outlines, pin function definitions, software interface, and electrical characteristics. Transceivers based on this MSA will provide transmit and receive interfaces for metro DWDM multi-service routers, multi-service provisioning, optical transmission platforms, and digital cross-connects.
MSA-compliant DWDM transceivers will allow network service providers to plug in a DWDM transceiver exactly when and where it's needed, and at any wavelength, reducing inventory costs. The ability to install the transceivers into live systems eliminates system downtime during upgrades and service calls. The multi-rate feature (from 155 Mbits/sec to 2.7 Gbits/sec) allows operators to offer flexible service as well.
"This MSA has been well received by the leading optical network equipment manufacturers," asserts David Chown, general manager of Agilent's Telecom Fiber Optic Component Operation. "The benefits of lower inventory costs, reduced system downtime, and easy field maintenance are compelling propositions for manufacturers and their customers."
Network equipment manufacturers will also benefit from the pluggability feature, as it eliminates cumbersome fiber "pigtails" and pin through-hole devices that are difficult to assemble in high-volume systems. These pluggable transceivers will not require soldering to the board or a board cut out, further reducing design and manufacturing time. The modules are suitable for both hot-pluggability in the field when mounted at the faceplate of the equipment and for cold-plugging "in-board" when field access is not required.
"The addition of six new members is a powerful reinforcement of the MSA and establishes it as the preeminent 2.5-Gbit/sec DWDM interface standard," contends Pat Walsh, vice president, Product Line Management, Optical Components, Nortel Networks.
"The DWDM MSA continues to gain traction and attract new members by providing the right technology, standards, and support the industry needs," adds Mark Granahan, vice president of Agere's Optical Access and Transport division. "The MSA gives designers confidence to deploy compliant devices without costly and time-consuming system redesign. Agere will continue to support and lead this industry-standard effort with cost-effective, highly integrated, IC-based transport solutions that access, move and store network information."
Founded in June 2002, the DWDM Pluggable Transceiver MSA group is an open forum, welcoming applications from transceiver manufacturers who wish to join. For more information and detailed technical specifications, visit www.hotplugdwdm.org.
