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
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'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
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:
(*1) XLMD2-MSA: TOSA and ROSA MSA for use in the 40 Gbit/s serial small form
factor transceivers, effective from July 2011. For more information, please
