MRV Adds 8Gbps Fibre Channel Transponder to LambdaDriver Family

Network Innovator MRV Brings 8Gbps Data Rate to Storage Distance Extension
Applications
CHATSWORTH, Calif.--(Business Wire)--
MRV COMMUNICATIONS, INC. (Nasdaq: MRVC), a leading provider of products and
services for out-of-band networking, WDM and optical transport, metro Ethernet,
fiber optic components, 10GE and other service aware networking products, today
announced the new, 8Gbps Fibre Channel pluggable module for its modular
LambdaDriver WDM system. The new 8Gbps Dual Transponder module is the highest
data rate member of MRV`s series of storage modules for the LambdaDriver
platform.

The 8Gbps FC Dual Transponder module offers customers unrepeated distances of up
to 80 km. Fitting into any chassis of the LambdaDriver family, these dense WDM
modules features MRV`s innovative pluggable optics that make its optical
transport systems among the most cost-effective solutions on the market.

"All mission critical storage applications need remote back up, and with this
new module, the LambdaDriver becomes one of the few systems on the market that
can provide the highest speed Fibre Channel link across the wide area," said
Noam Lotan, president and CEO of MRV.

While it offers the maximum 8Gbps Fibre Channel rate, the new dual transponder
module is backward compatible with existing LambdaDriver systems and features
automatic speed selection to also support both 4Gbps and 2Gbps data rates.
Customers can upgrade existing systems simply by adding this module to a
LambdaDriver chassis and scale the system according to bandwidth needs.

In the storage market in which latency and data integrity are critical, this
module offers LambdaDriver customers both low-latency and high data rate
transmission of 8Gbps Fibre Channel over the long haul. The transponder supports
remote loop-back functionality as a failover mechanism in the event of a network
outage and provides an essential tool for troubleshooting and maintenance
operations.

Both a multimode and a single mode optical SFP+ module are available for the
transponder, giving network managers a choice between 850 nm multimode optics
for distances up to 300m, or 1310nm single mode optics for distance up to 10Km
depending upon the installed cable plant and distance to the remote location.

The modules are available immediately from MRV`s sales force or its worldwide
distribution channel.

About the MRV's LambdaDriver Platforms

MRV's LambdaDriver WDM platforms provide flexible CWDM and DWDM solutions,
enabling enterprises to build campus-wide backbone networks and service
providers to create new revenue opportunities due to more efficient use of their
existing fiber infrastructure. Three different active chassis (LD400, LD800 and
LD1600) and 2 passive chassis (LPD100 and LDP300) with interchangeable modules
provide a solution for any network size and service density. Transparent
transport allows support for all high-speed LAN, WAN or SAN services. The
sub-rate TDM technology allows even more efficient use of the available fiber by
aggregating low rate protocols over one wavelength. The LambdaDriver platforms
support both CWDM and DWDM technologies, thus enabling a cost efficient initial
investment in infrastructure with CWDM and a smooth upgrade path towards full
capacity DWDM networks. LambdaDriver platforms are NEBS certified for use in
U.S. carrier central office applications. For more information, please visit
