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, CA---March 13, 2013---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�fs 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:

Leading Optical Chip and Module Manufacturers Announce New Pluggable Transceiver Module Multi-Source Agreement for 40 Gbps Solution with an Optical Device (XLMD2)

Fremont, CA---July 27, 2011---Mitsubishi Electric Corporation, OKI SEMICONDUCTOR CO., LTD., Opnext, Inc., Renesas Electronics Corporation and Sumitomo Electric Industries, Ltd., today announced a transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) Multi-Source Agreement (MSA) for 40 Gbps pluggable transceiver modules. This initiative was established to meet increased demand for pluggable 40 Gbps serial modules, similar to the CFP MSA.^*1.

In an upcoming MSA meeting, the member companies will specify the common mechanical dimensions, footprint, pin functions and performance of the optical transmitter and receiver devices. The TOSA/ROSA MSA specifies key features including a low-profile and compact fit for pluggable modules and simple electrical interfaces that provide cost effective solutions.

The transmission speed of 40 Gbps is the highest modulation speed, commercially-available, that uses the simple light on/off keying or serial transmission scheme. 300-pin MSA ^*2 transceivers using 1550 nm light source devices are widely available for the 2 km application. Recently,
40 Gbps serial transmission over 10 km was demonstrated using 1310 nm light source devices.
In addition to ITU-T 40Gbps serial transmission standards: VSR2000-3R2 for 2 km and P1I1-3D1 for 10 km ^*3, the IEEE has recently defined a 40 Gbps serial interface for 2 km (40GBASE-FR) ^*4. The demand for 40Gbps serial transmissions is growing in telecommunication, data and IP communication applications.
In today�fs 300-pin MSA transceiver module market, XLMD MSA ^*5 TOSAs and ROSAs are widely adopted. Following the release of the CFP MSA, 40 Gbps pluggable transceiver modules are now required to offer easy handling and maintenance. New low profile, compact TOSAs and ROSAs are essential components for future downsized pluggable transceiver modules.
"The TOSA/ROSA agreement will leverage the 40 Gbps market to achieve compact, low-power-consumption pluggable modules, which will provide advanced 40 Gbps serial solutions to high capacity network and storage systems," said an MSA Committee spokesperson. In the future, the MSA will continue to define specifications that consider future advanced technologies, such as 1310 nm light source devices and direct modulation lasers.
The new TOSA/ROSA MSA defines both the laser transmitter devices and the PIN Photodiode - Trans-impedance amplifier (PIN-TIA) receiver devices that comply with 40 Gbps interface standards. The MSA targets transmission modules for more than 10 km applications.

This MSA intends to establish compatible optical devices as defined below.
(1) Common mechanical dimensions;
(2) Common interface with common printed circuit board (PCB) design of 40 Gbps optical transceiver modules;
(3) Common pin assignment and functions; and
(4) Common electrical and optical characteristics.

The MSA Committee plans to release the specifications within one year.

Anaheim, Ca., March 26, 2007 – Eudyna Devices Inc., Mitsubishi Electric Corp., NEC Electronics Corp., Oki Electric Industry Co., Ltd., Opnext, Inc. and Sumitomo Electric Industries, Ltd., today announced at OFC/NFOEC 2007 the formation of a Multi-Source Agreement (MSA) for compatible sources of optical transmitter and receiver devices for use in 40 Gbit/s optical transceiver modules. This initiative, created in response to an increase in projected demand, specifies the common mechanical dimensions, footprint, pin functions and performance of the optical transmitter and receiver devices; key compact optical components used in 40 Gbit/s optical transceiver modules.

"This agreement will help support the emergence of the 40 Gbit/s compact module market, providing advanced solutions to high capacity network and storage systems," said the MSA Committee. “In the long term, all members will consolidate their current models into MSA compliant products in order to achieve consistent customer delivery and market growth.”

In order to construct the broadband internetworking infrastructure, 10 Gbit/s optical transmission interfaces are widely deployed in Metropolitan Area Network (MAN), Local Area Network (LAN) and Storage Area Network (SAN). 40 Gbit/s optical transmission interfaces are currently being used within the industry. The 10 Gbit/s interfaces, TOSA and ROSA devices, that were made compatible among manufacturers through a 10 Gbit/s Miniature Device Multi-Source Agreement (XMD-MSA), have been supplied and widely recognized as the industry standard. Subsequently, those companies involved in 40 Gbit/s optical interfaces, the six chip and module manufactures, formed an MSA for optical devices for quick development and the ease of component procurement for optical transceiver modules.

The new MSA defines the external-modulation laser transmitter devices and the PIN Photodiode - Trans-impedance amplifier (PIN-TIA) receiver devices that comply with 40 Gbit/s interface standard of OC-768. The MSA targets transmission modules for up to 2km applications.

This MSA intends to establish the compatible optical devices as defined below:
(1) Common mechanical dimensions
(2) Common interface with common PCB design of 40 Gbit/s optical transceiver modules
(3) Common pin assignment and functions
(4) Common electrical and optical characteristics

The MSA Committee plans to release the specifications for pigtail type optical devices within 2007 and to finalize TOSA/ROSA specifications in step in accordance with the future standardization of pluggable optical transceivers.
