Eudyna Devices Inc., Mitsubishi Electric Corp., NEC Electronics Corp., Oki Electric Industry Co. Ltd, Opnext Inc. and Sumitomo Electric Industries Ltd announced the formation of a Multi-Source Agreement (MSA) for compatible sources of optical transmitter and receiver devices for use in 40Gbps optical transceiver modules.

The initiative specifies the common mechanical dimensions, footprint, pin functions and performance of the optical transmitter and receiver devices and key compact optical components used in 40Gbps optical transceiver modules. The six chip and module manufactures formed the MSA for 40Gbps optical devices for quick development and the ease of component procurement for optical transceiver modules.

The MSA intends to establish common mechanical dimensions; common interface with common PCB design of 40Gbps optical transceiver modules; common pin assignment and functions and common electrical and optical characteristics.

In addition, the MSA defines the external-modulation laser transmitter devices and the PIN Photodiode-Transimpedance amplifier receiver devices that comply with 40Gbps interface standard of OC-768 and targets transmission modules for up to 2km applications.

"This agreement will help support the emergence of the 40Gbps 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."

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.
