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-MCF6xx Multichannel Media
Converter has six channels while the AT-MCF12xx Multichannel Media
Converter has twelve channels.
Figure 3 Twisted Pair Port and Fiber Optic Port Channel (Model AT-MCF12SC)
Twisted Pair Ports. The twisted pair ports are IEEE 802.3 10Base-T compatible,
and thus operate at 10 Mbps only. The ports require Category 3 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
10 Mbps. To connect a switch, hub, or router to a twisted pair port requires a
straight-through cable. To connect a workstation to a twisted pair port
requires a crossover cable.
10Base-FL Fiber Optic Ports. The 10Base-FL fiber optic ports operate at 10 Mbps
and, depending on the model, function 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 a list of the available types of
connectors.
