Leading Optical Device Manufacturers Release Common Specifications for 40 Gbit/s Solutions Based on XLMD Optical Device Multi-Source Agreement

Multi-Source Agreement Enables Multiple Vendors to Produce 40
Gbit/s Optical Devices Based on a Unified Standard
TOKYO & SAN DIEGO--(Business Wire)--
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/s Optical Device Multi-Source Agreement (XLMD-MSA(*1)),
introduced by the six companies 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(*2) receiver devices that comply with 40 Gbit/s
interface standard for SONET OC-768(*3).

10 Gbit/s optical transmission interfaces are widely deployed in
Metropolitan Area Networks (MAN), Local Area Networks (LAN) and
Storage Area Networks (SAN). These networks currently form the
backbone of broadband infrastructure, consequently increasing the
popularity of 40 Gbit/s optical transmission interfaces. The XLMD-MSA
aims to establish compatible sources of 40 Gbit/s optical transmitter
and receiver devices embedded into the 40 Gbit/s optical transceiver
modules. This agreement will accelerate the growth of the 40 Gbit/s
transceiver module market, providing advanced solutions to high
capacity network and storage systems. All members 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 a dual SMPM(*4)
connectors

-- Optical and electrical characteristics

The specifications are now available at the XLMD-MSA web site.

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

Notes:

1) XLMD-MSA: 40Gbit/s Miniature Device Multi Source Agreement
among Eudyna Devices Inc., Mitsubishi Electric Corp., NEC Electronics
Corp., Oki Electric Industry Co., Ltd., Opnext Inc. and Sumitomo
Electric Industries, Ltd, effective from March 2007.

2) PIN-TIA: PIN photodiode with a trans-impedance amplifier.

3) SONET OC-768: SONET is synchronous optical networking. OC-768
is a network line with 40Gbit/s transmission rate.

4) SMPM: Small-sized coaxial connectors specified in MIL-STD-348A,
such as GPPO(TM). GPPO(TM) is a trademark of Corning Gilbert Inc.
