About 16-Port 100BASE-FX Interface Modules

The Catalyst 8540 supports a 16-port 100BASE-FX interface module that provides 100-Mbps Layer 2 or Layer 3 multimode fiber-optic connections. It supports full-duplex connections and Fast EtherChannel operation. The 16-port 100BASE-FX interface module is available with 16 KB or 64 KB of memory, which is used by the routing tables.

Interface Ports Supported

Table 20-1 identifies the maximum number of interface ports supported in
each system.

Figure 20-1 shows a 16-port 100BASE-FX interface module.

Connections Supported

The 16-port 100BASE-FX interface module provides 100-Mbps, multimode fiber-optic connections. It supports full-duplex connections and Fast EtherChannel operation. It has 16 multimode fiber ports that use MT-RJ connectors.

Cabling 16-port 100BASE-FX Interface Modules

This section describes supported cabling configurations for the 16-port 100BASE-FX interface module.

Note   "Connectors and Connector Pinouts," lists cabling requirements.

Interface Module Connectors

To connect the 16-port 100BASE-FX interface module to an external device, use MT-RJ connectors. (See Figure 20-2.)
