Overview

Twisted Pair and Fiber Optic Ports

The twisted pair and fiber optic ports on the unit are paired together (see

Figure 3). Each pair is referred to as a “channel” and each channel functions

as an independent media converter. The AT-MCF106xx Multichannel Media

Converter has six channels while the AT-MCF112xx Series Multichannel

Media Converter has twelve channels.

Twisted Pair Ports

The twisted pair ports are IEEE 802.3 100Base-TX compatible, and thus

operate at 100 Mbps only. The ports require Category 5 or better cabling and

allow for a distance of 100 meters (328 feet).

The devices that you connect to the twisted pair ports must operate at 100

Mbps. To connect a switch, hub, or router to one of these ports, you will use a

straight-through cable. Connecting a workstation to a twisted pair port

requires a crossover cable.

100Base-FX Fiber Optic Ports

The 100Base-FX fiber optic ports operate at 100 Mbps and, depending on the

model, operate with multimode or single-mode fiber optic cabling.

The type of connector on the fiber optic ports will depend on the system model

you purchased. Refer to Table 1 on page 2 for the available types of

connectors.
