Finisar demonstrates XFP transceiver over 300m of legacy multimode fiber and 80km DWDM XFP 10-Gbit/s optical transceiver at OFC
February 24, 2004
SUNNYVALE, Calif. -- Finisar Corporation (NASDAQ: FNSR), a technology leader in Gigabit fiber optic solutions for high-speed data and telecommunication networks, announced today that it plans to demonstrate the first 10Gb/s XFP optical transceiver operating over 300 meters of legacy multimode fiber at OFC 2004 in Los Angeles this week.
Finisar's new XFP optical module utilizes an uncooled 1310nm laser and Electronic Dispersion Compensation (EDC) technology to transmit 10Gb/s error-free over a distance of 300 meters using legacy multimode fiber. This includes the 160/500MHz-km grade 62.5/125um fiber that constitutes the vast majority of the current infrastructure in the Enterprise LAN environment and which needs to be supported with a cost-effective solution when upgrading to 10-Gigabit Ethernet. A new optical interface standard based on EDC technology to support this application is currently under study by the IEEE.
Other 10Gb/s transceivers and transponders use 850nm lasers (10GBASE-SR) but can only transmit 26 meters on the most common type of legacy fiber optics. In order for them to reach up to 300 meters, end-users need to deploy new high-bandwidth multimode fiber (2000MHz-km) at significant expense. Another multimode solution based on the 10GBASE-LX4 interface uses four separate lasers of different wavelengths to achieve 300 meters, which translates into higher power dissipation, higher costs and reduced reliability.

Finisar Corporation (NASDAQ: FNSR), a technology leader in Gigabit fiber optic solutions for high-speed data and telecommunication networks, announced today that it plans to demonstrate an 80km DWDM XFP 10Gb/s optical transceiver at OFC 2004 in Los Angeles this week.
Finisar's new FTRX-3811-3 XFP transceiver utilizes a temperature-controlled low-chirp 1550nm EML and a high-sensitivity APD receiver, and targets OC-192 LR-2c as well as 100GHz ITU-Grid DWDM applications. It can also support 80km 10-Gigabit Ethernet and Fibre Channel links and has a maximum power consumption of 3.5W. Finisar's hot-pluggable 80km XFP transceiver has the same mechanical footprint as the 10km and 40km versions, and thus fits in the standard XFP MSA cage.
Finisar's 80km XFP optical transceivers are the first ever to be publicly demonstrated. They provide the cost and power savings inherent to the XFP form factor, enabling cost-effective 10Gb/s optical links for long-reach and metropolitan-area DWDM applications.
"This new 80km DWDM XFP transceiver proves once again that the XFP form factor is capable of supporting virtually all types of 10Gb/s applications, from short-reach interconnects to metropolitan-area long distance links," said Beck Mason, Director of High-Performance Transceiver Engineering at Finisar. "As the first company to demonstrate an 80km XFP transceiver, Finisar strengthens its leadership role in innovative transceiver technology."
