TOKYO -- (BUSINESS WIRE) --
Hitachi Cable, Ltd. (TOKYO:5812) has announced the development of an XLGMC-1001 media converter. The XLGMC-1001 is the world's first*1 product to comply*2 with the 40 Gigabit Ethernet*3 specifications currently under standardization by the IEEE802 committee.*4 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*5 and SONET*6 to 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 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,*7 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*8 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)*9 and Polarization Mode Dispersion (PMD)*10 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*11 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*12 providing support for 40GBASE-LR4 for connection to single-mode optical fiber cable, enabling interconnection to a wide range of 40 Gigabit Ethernet equipments.
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.
Hitachi 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.
