6 September 2002 -- JDS Uniphase Corp has expanded its Gigabit Ethernet and Fibre Channel offerings for the datacoms market by announcing a 10 Gigabit Ethernet (10GbE) optical transceiver which is compliant with the IEEE 802.3ae standard and the XENPAK multi-sourcing agreement (MSA).
XENPAK is the most widely accepted design of 10GbE transceivers and describes form, fit and function by providing mechanical, electrical and optical standards.
"Data communications and Gigabit Ethernet are in demand because campus operations, enterprises and global organizations have a continued need to upgrade their networks under increasing cost restraints," said Don Bossi, president of JDS Uniphase's Transmission Group. The product exceeds IEEE LAN-PHY specifications, he claims.
JDS Uniphase's 10GbE XENPAK transceivers draw just 4.2W of power and, when used at both ends of the link, are guaranteed for distances of up to 15 km (50% more than the IEEE standard). In addition, fully compliant pairs of these transceivers have been successfully demonstrated at distances of up to 40km.
The laser driver and receiver amplifier ICs are JDS Uniphase's proprietary analogue designs and are fabricated using silicon-germanium (SiGe) technology. EMI performance is certified to 8dB below FCC class B (Residential), allowing multiple 10GbE XENPAK transceivers to be installed on a single line-card.
With 10 Gigabit backbones installed, companies will be able to provide Gigabit Ethernet service to workstations and, eventually, to the desktop, supporting applications such as streaming video, medical imaging, centralised applications, and high-end graphics.
Also, 10GbE will provide infrastructure for both network-attached storage (NAS) and storage area networks (SAN). Applications for Gigabit Ethernet in storage networks include: business continuance/disaster recovery, remote backup, storage on demand and streaming media.
