Agilent Technologies, Nortel Networks, and Agere Systems announce Multi-Source Agreement for Hot-Pluggable OC-48 DWDM transceivers

Agilent Technologies, Nortel Networks, and Agere Systems have announced a multi-source agreement (MSA) for hot-pluggable 2.5-Gbit/sec (OC-48) transceiver modules used in metro DWDM optical networking systems. Transceivers developed using this new specification can help improve network planning, commissioning, and maintenance of optical networks and reduce system downtime, claim the companies.

The DWDM Pluggable Transceiver MSA establishes a standard that specifies uniformity for 2.5-Gbit/sec DWDM transceiver package outlines, pin function definitions, software interface, and electrical characteristics.

Agilent, Nortel Networks, and Agere will independently develop and market the compact, DWDM transceivers based on the new standard, ensuring that optical systems manufacturers have a choice among compatible sources.

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.

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 optical interface will be a standard LC connector.

The DWDM Pluggable Transceiver MSA group is an open forum, welcoming both transceiver and network equipment manufacturers as new members. For more information on joining the MSA and detailed technical specifications, visit www.hotplugdwdm.org.
