Chapter 1: Overview

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.
