Leading Optical Chip and Module Manufacturers Announce 10 Gbit/s Miniature Device -XMD- MSA for TOSA/ROSA

Business Wire, Sept 1, 2004

TOKYO -- MSA Enables Multiple Vendors to Produce Short- and Long- Reach TOSA/ROSA XFPs Based on a Unified Standard

Leading Optical Manufacturers Avanex Corp., Eudyna Devices Inc., Mitsubishi Electric Corp., Oki Electric Industry Co., Ltd., Opnext, Inc., Sumitomo Electric Industries, Ltd., and TriQuint Semiconductor, Inc., today announced the release of new common specifications for long-reach optical devices based on a 10 Gbit/s Miniature Device Multi-Source Agreement (XMD-MSA). The XMD-MSA specifications are designed for applications from short-to-long reach transmission functions.

Specifications established by the XMD-MSA enables the use of optical devices from multiple suppliers. The XMD-MSA has been created to establish compatible sources of 10 Gbit/s Transmitter Optical Sub-Assembly (TOSA) and Receiver Optical Sub-Assembly (ROSA) devices embedded into the 10 Gbit/s small form factor pluggable (XFP) MSA modules. The XFP module has been designed for use in large capacity network and data storage systems. This XMD-MSA covers optical devices that comply with 10 Gbit/s interface standards, including 10 Gigabit Ethernet, 10 Gigabit Fiber Channel and SONET OC-192.

The newly available XMD-MSA specifications detail the semiconductor-based external modulator TOSA and Avalanche Photo-Diode Trans-Impedance Amplifier (APD-TIA) for long-reach (beyond 20 km) applications. XMD-MSA specifications now cover transmission applications for most optical networking systems.

These specifications for interchangeable TOSA/ROSA devices include:

--Common Mechanical Dimensions including optical connector interface that determines the design of the XFP optical head

--Common electrical interface standards using flexible printed circuit (FPC)

--Optical and electrical characteristics

This MSA enhances the XMD-MSA for direct-modulation Distributed-Feed-back (DFB) or Fabry-Perot (FP) laser TOSA, and the PIN Photodiode - Trans-Impedance Amplifier (PIN-TIA) ROSA for short-reach applications up to 20km, previously announced on June 7th, 2004.

Members of the XMD-MSA (detailed below) can provide specifications for the new multi-source agreement.

The MSA committee plans to revise TOSA/ROSA specifications issued on June 7. The revised specifications will be available on September 30 from any member of the XMD-MSA.
