MRV Receives Brocade Data Center Ready Status for End-to-End Storage Networking Interoperability

MRV Fiber Driver 10Gbit/sec SAN System is Interoperable in Brocade-Based,
Multi-Vendor Environments
CHATSWORTH, Calif.--(Business Wire)--
MRV (NASDAQ: MRVC), a leading provider of products and services for out-of-band
networking, optical transport, metro Ethernet, and fiber optic components,
announced today that the Fiber Driver 10 Gbps XFP-based optical module has been
verified by Brocade as interoperable with Brocade-based Storage Area Network
(SAN) infrastructure, according to the testing requirements of the Brocade Data
Center Ready program, an end-to-end interoperability initiative for SANs.

The Brocade Data Center Ready program offers companies a complete certification
of their products in Brocade SAN fabric environments. Certification included
comprehensive and rigorous testing of the MRV Fiber Driver 10Gbit/sec SAN
Platform for compatibility with Brocade switches and directors in multi-vendor
SAN environments.

"With both of our key optical transport platforms now offering industry
interoperable SAN back up links, customers have the flexibility of choosing
either CWDM or DWDM backbones," said Noam Lotan, CEO of MRV Communications. "By
proving interoperability between MRV`s Fiber Driver product line and Brocade`s
SAN switches, our customers can be assured that MRV`s products can be deployed
immediately and seamlessly in a multi-vendor network."

The Fiber Driver 10Gbps media modules combine ultra high-speed protocol support
with the flexibility of XFP transceivers that support 10Gbps Fibre Channel along
with SONET OC-192, 10 Gigabit Ethernet and G.709. MRV`s Fiber Driver product
line is an innovative optical multiservice platform that provides differentiated
services including fiber grooming (Media conversion, Distance extension and
Signal repeating), converter-based service demarcation, advanced CWDM and DWDM
solutions and digital video distribution. The Fiber Driver platform can act as a
media converter, a repeater or a WDM transponder with a simple change-out of
hot-swappable multi-functional modules. Despite its compact 3RU size, it can be
configured for 44 sub-3Gbps and 22 1/2/4 Gbps or 10Gbps wavelengths in its
energy efficient chassis. The Fiber Driver provides a wide range of optical
transport solutions to enterprise, campus and metro networks with distances of
80-100km.

"We are pleased that MRV has successfully completed the Brocade Data Center
Ready testing with Brocade switches and directors in multi-vendor SAN
environments," said Ben Taft, senior director of Strategic Alliances at Brocade.
"Storage area networks are being deployed worldwide at a rapid rate as a
scalable, high-performance networking foundation for storage environments. The
Brocade Data Center Ready program is an example of our continued commitment to
delivering end-to-end interoperability to customers."

About the Brocade Data Center Ready Program

The Brocade Data Center Ready program is a comprehensive testing and
configuration initiative designed to foster end-to-end SAN interoperability. As
part of the program, testing is conducted in SAN configurations that include a
heterogeneous mix of servers, storage systems, Brocade switches, SAN management
and enterprise applications, and other SAN technologies. Brocade has created an
interoperability lab featuring a heterogeneous SAN fabric, in which the company
tests and validates partner equipment in specific configurations. Vendors
receive Brocade Data Center Ready qualification after completing tests to
confirm that vendors` products meet interoperability guidelines. For more
