Finisar Delivers GBIC Optical Transceivers for 80 km Data Links

Finisar Delivers GBIC Optical Transceivers for 80 km Data Links SUNNYVALE, Calif.--(BUSINESS WIRE)--April 26, 2000--Finisar Corporation (Nasdaq:FNSR) announced today the availability of a family of new Extended GBIC Optical Transceivers for Gigabit data transmission over distances up to 80 km. These "smart" transceivers are used to build high-speed data links over single-mode fiber optics. "These new Finisar transceiver modules provide cost-effective solutions for LAN and SAN applications where Gigabit-rate signals need to be transported around cities and across campuses," said Christian Urricariet, Finisar's Product Marketing Manager for Optical Subsystems.

These Gigabit-rate transceivers meet or exceed the electrical, mechanical and environmental requirements of the Gigabit Interface Converter (GBIC) Standard. They also comply with all functional requirements in the Gigabit Ethernet and Fibre Channel standards. Finisar's state-of-the-art optoelectronics design enables the 1550 nm FTR-1519 to operate over distances up to 80 km, and the 1310 nm FTR-1319-5A-30 up to 30 km, both using standard single-mode fibers. These new Extended GBIC transceivers are Class 1 devices per FDA/CDRH and IEC 825-1 laser safety regulations.

These "smart" GBIC transceivers include Finisar's unique built-in optical test, monitoring, and reporting system in addition to the standard GBIC Serial ID. This test system allows switches, hubs, storage arrays, and adapter cards to provide optical test information to their users. Each GBIC can automatically report status information on parameters such as laser current, laser temperature and transmitted power. This information empowers users to diagnose link or loop optical problems without deploying a service technician.

Electromagnetic interference (EMI) is an increasingly important design parameter in the new Gigabit-rate data communication systems. All Finisar GBIC transceiver modules are built with fully metallic enclosures to ensure superior emission control and FCC test margins.

Optical transceivers are utilized by networking manufacturers in their switches, hubs, storage arrays, and adapter cards for LAN, SAN and WAN applications to convert Gigabit-rate electrical signals to optical signals and vice-versa for transmission over fiber optics.
