INTRODUCTION

Thank you for choosing the C1000SX Gigabit fiber Ethernet Card for

32/64-bit PCI Bus-equipped personal computers. The Gigabit fiber

Ethernet Card is ideal for speeding up data transfers for network servers

and other computers, such as those used for video-conferencing, that send

and/or receive large amounts of data. It also includes the newest

networking technologies, such as VLAN and multicasting support, that

use network bandwidth more efficiently and further help the card

maximize data throughput.

u SC type connector for 50/125µm or 62.5/125µm multi-mode fiber

u Supports Full-duplex mode doubles network data rate to 2000Mbps

u Built-in FIFO buffers reduces overhead of memory transfers

u Virtual LAN (VLAN) and long frame support. VLAN tag insertion

supports for transmit packets. VLAN tag detection and removal for

receive packets

u 802.3x Full duplex flow control, including automatic transmission

of Pause frames based on Rx FIFO thresholds

u Two LED indicators for easy diagnostic

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the

same packet structure, format, and support for CSMA/CD protocol, full

duplex, and management objects, but with a tenfold increase in

theoretical throughput over 100Mbps Fast Ethernet and a one hundred-

fold increase over 10Mbps Ethernet.

The increased speed and extra bandwidth offered by Gigabit Ethernet is

essential to coping with the network bottlenecks that frequently develop
