Enhanced 10/100Base-TX to 100Base-FX Converter

2 Hardware Description

Product Overview

The Converter is enhanced with Link Fault Signaling
(LFS) and Loopback Test (LBK) functions to offer the
most comprehensive network status monitoring and
connection diagnostics. It is designed for large
workgroups who demand higher speed and wider
bandwidth. It allows migration and expansion from a
copper-based Ethernet to a fiber optic Fast Ethernet.

It features automatic MDI detection setting. This
function allows for simple direct connection to a
workstation, switch or hub. Therefore, network
managers no longer need to worry about cable type
configuration when establishing a connection between
RJ-45 ports.

This Converter is equipped with an RJ-45 port and a
fiber optic ST or SC or WDM port. This allows it to
quickly integrate a 10/100Base-TX network into a
100Base-FX (fiber) network.

Enhanced 10/100Base-TX to 100Base-FX Converter

It features DIP switches for manual half or full duplex
mode configuration on both copper and fiber ports. In
full duplex mode, this Converter has the ability to
support distances of up to 2 kilometers for multi-mode
fiber and up to 60 kilometers for long-haul single mode
fiber between a LAN switch, file server or another
networking device.
