Leading Optical Chip and Module Manufacturers Target 10 Gbit/s Solution with a Miniature Device (XMD) MSA for XFP TOSA and ROSA

Posted on: Monday, 23 February 2004, 06:00 CST

OPTICAL FIBER COMMUNICATION CONFERENCE 2004, LOS ANGELES, Feb. 23

/PRNewswire/ -- Fujitsu Quantum Devices, Ltd., Mitsubishi Electric Corp., Oki Electric Industry Co., Ltd., Opnext, Inc. and Sumitomo Electric Industries, Ltd., today announced at the Optical Fiber Communication Conference 2004 (OFC 2004) the formation of a Multi-Source Agreement (MSA) to establish compatible sources of 10Gbit/s Transmitter Optical Sub-Assembly (TOSA) and Receiver Optical Sub-Assembly (ROSA) for use in the 10 Gbit/s XFP MSA defined module. This initiative standardizes the common mechanical dimensions, footprint and pin functions of the TOSA/ROSA devices; key compact optical components used in XFP modules.

"This agreement will help support the emergence of the 10 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 lower costs and consistent customer delivery."

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 systems. There have been many efforts to establish industrial standards in optical modules resulting in the formation of several multi-source agreements (MSA) such as 300-pin MSA (http://www.300pinmsa.org/), XENPAK (http://www.xenpak.org/), X2 (http://www.x2msa.org/) and XFP (http://www.xfpmsa.org/). XFP is the most advanced MSA providing compact 10 Gbit/s modules while achieving lower power consumption at a significantly lower cost. To fulfill the requirements, the five chip and module manufactures formed a MSA for TOSA/ROSA devices to develop devices with the capability to reduce the cost and power consumption within XFP modules.

The new MSA defines the direct-modulation Distributed-Feed-back (DFB)/ Fabry-Perot (FP) laser TOSA and the PIN Photodiode -- Trans-impedance amplifier (PIN-TIA) ROSA complying with 10 Gbit/s interface standard of OC-192, 0GbE and 10G FC. The MSA targets 1310nm transmission modules for up to 20km applications and 1550nm transmission modules beyond 40km applications. This MSA intends to establish the compatible TOSA/ROSA as defined below:

(1) Common mechanical dimensions including the LC-receptacle parts and

mechanically mounting method to XFP modules

(2) Common interface with common XFP PCB design

(3) Common pin assignment and functions

(4) Common electrical and optical characteristics

The MSA is now finalizing the TOSA/ROSA specifications and working samples will be available soon in 2004.
