Fiber Optic Ports
The fiber optic ports have duplex LC connectors. They are
100Base-FX compliant with a fixed operating speed of 100
Mbps. The duplex mode of these ports can be either half- or
full-duplex mode. The default setting is full duplex. Adjusting
the duplex mode of a fiber optic port requires the optional
management module for the chassis.
The fiber optic ports on the AT-MCF2012LC module have a
maximum operating distance of 2 km and use 50/125 or
62.5125 µm (core/cladding) multimode fiber optic cable.
The fiber optic ports on the AT-MCF2012LC/1 module have
a maximum operating distance of 20 km and use 9/125 µm
single-mode fiber optic cable.
Note
The maximum operating distances of the fiber optic
ports assume full-duplex operation. A fiber optic port
operating in half-duplex mode will have a maximum
operating distance that is significantly less.
Refer to “100Base-FX Fiber Optic Port Specifications” on
page 63 for the operating specifications of the fiber optic
ports.
