40-Gbit/sec XLMD-MSA releases common specs

FEBRUARY 21, 2008 -- The newly available XLMD-MSA specifications detail the external-modulation laser transmitter devices with built-in driver ICs and the PIN-TIA receiver devices that comply with 40-Gbit/sec interface standard for SONET OC-768.

FEBRUARY 21, 2008 -- Eudyna Devices Inc., Mitsubishi Electric Corp., NEC Electronics Corp., Oki Electric Industry Co. Ltd., Opnext Inc., and Sumitomo Electric Industries Ltd. today announced, in advance of OFC/NFOEC, common specifications for pigtail-type optical devices based on the 40-Gbit/sec Optical Device Multi-Source Agreement (XLMD-MSA), introduced by the companies back in March 2007.

The newly available XLMD-MSA specifications detail the external-modulation laser transmitter devices with built-in driver ICs and the PIN-TIA (PIN photodiode with a trans-impedance amplifier) receiver devices that comply with 40-Gbit/sec interface standard for SONET OC-768.

10-Gbit/sec optical transmission interfaces are widely deployed in metro, local, and storage area networks. These networks currently form the backbone of broadband infrastructure, consequently increasing the popularity of 40-Gbit/sec optical transmission interfaces.

MSA members say the XLMD-MSA aims to establish compatible sources of 40-Gbit/sec optical transmitter and receiver devices embedded into the 40-Gbit/sec optical transceiver modules. This agreement will accelerate the growth of the 40-Gbit/sec transceiver module market, providing advanced solutions to high capacity network and storage systems. All members say they will promote the MSA-compliant products in order to achieve consistent customer delivery and market growth.

The XLMD-MSA specifications for compatible optical devices include:
• Mechanical dimensions and pin assignments of pigtail type optical devices;
• High-speed electrical interface using dual SMPM connectors; and
• Optical and electrical characteristics.

The specifications are now available at the XLMD-MSA web site, www.xlmdmsa.org.

In accordance with the future standardization of 40-Gbit/sec pluggable optical transceivers, the XLMD-MSA committee says it will continue to discuss the corresponding optical device specifications.
