Finisar delivers a copper GBIC transceiver that supports Gigabit Ethernet over Category 5 UTP cable

Apr. 24, 2001--Finisar Corporation, a technology provider of gigabit fiber optic solutions for high-speed data networks, announced it is shipping a 1000BASE-T Copper GBIC transceiver module, the FCM-8519-3.

Finisar Corporation (Nasdaq: FNSR), a technology provider of gigabit fiber optic solutions for high-speed data networks, announced it is shipping a 1000BASE-T Copper GBIC transceiver module, the FCM-8519-3.

Utilizing Marvell's Alaska Gigabit Ethernet over copper PHY IC, the company's new GBIC transceiver allows networking equipment manufacturers to support Gigabit Ethernet links over existing Category 5 Unshielded Twisted Pair (UTP) cabling, up to a distance of 100 meters.

The FCM-8519-3 complies with the mechanical and Serial ID interoperability requirements in the GBIC Standard. Its line interface complies with the 1000BASE-T standard, per IEEE Std 802.3ab,Iallowing full-duplex transmission of a 1.25Gb/s signal to a distance of 100 meters, with an operating temperature range between 0(degree)C and 65(degree)C.

GBIC transceivers are hot-pluggable modules utilized by networking equipment manufacturers in their switches, hubs, storage arrays, and adapter cards to convert gigabit-rate electrical signals on the host board to optical or copper signals and vice-versa, for transmission over fiber optic and copper transmission lines.

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.
