Leading Optical Component Manufacturers Release Multi-Source Agreement Specifications For 40 Gbit/s Serial Solution Based On XLMD2 Miniature Optical Device For Pluggable Transceivers

SAN JOSE, Calif., March 13, 2013 /PRNewswire/ -- Five leading optical component manufacturers including LAPIS Semiconductor Co. Ltd., Mitsubishi Electric Corporation, Oclaro, Inc., Renesas Electronics Corporation and Sumitomo Electric Industries, Ltd., today announced the release of new common specifications for transmitter optical sub-assemblies (TOSAs) and receiver optical sub-assemblies (ROSAs). These specifications are based on the 40 Gbit/s serial Multi-Source Agreement (XLMD2-MSA *1) for 40 Gbit/s pluggable transceiver modules such as the CFP MSA *2.


The transmission speed of 40 Gbit/s is the highest commercially-available rate that uses the simple light on/off keying or serial transmission scheme. CFP transceivers and 300-pin MSA *3 transceivers are widely available for the 40 Gbit/s serial application.

In addition to ITU-T 40G serial transmission standards, VSR2000-3R2 for 2 km and P1I1-3D1 for 10 km *4, the IEEE defined a 40 Gbit/s serial interface for 2 km (40GBASE-FR) *5. The demand for 40G serial transmission is growing in the fields of telecommunications as well as data and IP communications.

In today¬Ā's 300-pin MSA and CFP transceiver module market, XLMD-MSA *6 TOSAs and ROSAs are widely adopted. With the introduction of the CFP2/4 *2 MSA, thin, miniature TOSAs and ROSAs are essential for downsizing the pluggable transceiver modules.

The XLMD2-MSA aims to establish compatible sources of 40 Gbit/s miniature optical transmitter and receiver devices embedded into the compact 40 Gbit/s serial pluggable optical transceiver modules. Companies adopting the XLMD2-MSA will promote MSA-compliant products in order to meet customer demand and expand the market.

The XLMD2-MSA specifications include mechanical dimensions, interfaces with a common printed circuit board (PCB) design, pin assignment and electrical characteristics for the following compatible optical devices:

(1)   Cooled EMwL *7 TOSA with built-in driver IC; (2)   Cooled EMwL TOSA;(3)   Cooled DML *8 TOSA;(4)   Uncooled DML TOSA; and(5)   PIN-TIA *9 ROSA.

These specifications are now available at the XLMD-MSA web site:
