XLGMC-1001 Media Converter for 40 Gigabit Ethernet From Hitachi Cable

Hitachi Cable, Ltd. has announced the development
of an XLGMC-1001 media converter. The XLGMC-1001 is the world’s first
product to comply with the 40 Gigabit Ethernet specifications
currently under standardization by the IEEE802 committee. The product
is slated for release in June 2010, when the 40 Gigabit Ethernet
standard is expected to be officially released.

The growing
diversity of IT systems, including IP telephony and TV conference
systems, as well as conventional mission-critical tasks, Web access,
e-mail transmission/reception, and file-sharing, have placed enormous
burdens on the networks currently used by corporations. To handle
greater data transfer volumes, companies are now switching interoffice
networks from conventional dedicated telecommunication lines such as
ATM and SONETto faster, higher-capacity, and less costly wide-area
Ethernet networks. In light of this trend and to meet growing traffic
volume, the IEEE802 committee is working to standardize next-generation
40 Gigabit/100 Gigabit Ethernet.

In response, Hitachi Cable has
developed an [no need XLGMC-1001 media converter that supports the new
40 Gigabit Ethernet interface standard, the first such product anywhere
in the world. The company plans to introduce the product in June 2010,
when the 40 Gigabit/100 Gigabit Ethernet standard is expected to be
officially released.

Hitachi Cable has been manufacturing and
selling media converters and transmission devices to meet the needs of
its customers since 2000, when the company launched the GMX series,
the company’s first Gigabit Ethernet multiplex long-distance
transmission device developed based on in-house optical transceiver
R&D capabilities. These products are highly acclaimed for their
reliability and quality and are widely used by telecommunications
carriers in Japan, among others.

The newly-developed XLGMC-1001
adopts a Wavelength Division Multiplexing (WDM) transmission system
to divide the 40 Gigabit Ethernet signal into four 10 Gigabit signals
and encode them for transmission. This system eliminates the effects of
Chromatic Dispersion(CD) and Polarization Mode Dispersion (PMD)
that have become obstacles to high-speed transmission, achieving
one-fiber bidirectional transmission for a maximum transmission
distance of 80 km. This transmission performance is equivalent to that
of a conventional 10 Gigabit media converter.

The XLGMC-1001
offers a QSFP transceiver port as a user interface, providing
support for 40GBASE-SR4 for connections to multimode optical fiber
cable and 40GBASE-CR4 for connections to copper cable. Hitachi Cable
also plans to support XL2 small optical transceiver providing
support for 40GBASE-LR4 for connection to single-mode optical fiber
cable, enabling interconnection to a wide range of 40 Gigabit Ethernet

In addition, the XLGMC-1001 is packaged in the slim
1U (height: 44 mm) form factor, using miniaturized 10 Gigabit
electronic components and high-density packaging technologies.

Cable will continue to introduce products to meet the needs of
customers by making full use of its store of comprehensive Ethernet
technologies and drawing on its past delivery record and experience.
