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.
