Connecting to the Switched 100-Mbps Fiber-Optic Ports

Catalyst 1900 Series Installation and Configuration Guide

2-30

All ﬁber-optic connections between the switch and the attached device can be as follows:

• If the switch port is conﬁgured for half-duplex operation, you can connect the port to

another device that is within 412 meters of the switch.

• If the switch port and the port on the attached device are conﬁgured for full-duplex

operation, the connection can be over distances of up to 2 kilometers and provide up to

200 Mbps of bandwidth between the two devices.

The default duplex mode of these ports is half duplex. To change the duplex mode of these

ports to full-duplex or full-duplex ﬂow control, use the switch manager, management

console, or SNMP. (See the “Changing the Port Settings” section on page 3-15 or the “Port

Conﬁguration Menu” section on page 4-44.)

Note Duplex-mode autonegotiation is not supported on the 100-Mbps ﬁber-optic ports.

To connect a switch 100-Mbps ﬁber-optic port to another 100BaseFX device, follow these

steps:

Step 1 Remove the rubber plug from the port and the rubber cap from the cable

connectors.

Step 2 Connect one end of the MT-RJ patch cable to the 100-Mbps ﬁber-optic port on

the switch. Figure 2-14 shows an MT-RJ patch cable being connected to one of

the 100-Mbps ﬁber-optic ports on a Catalyst 1924F switch.
