Chapter 1 Overview
Cables and Connectors
Cables and Connectors
The interface connectors on the PA-5EFL port adapter are five pairs of ST-type receptacles, designated
as RX and TX. You can use all five connection pairs simultaneously or any combination of each pair
individually. Each connection pair supports IEEE 802.3 and Ethernet 10Base-FL interfaces compliant
with appropriate standards.
Figure 1-3
shows the ST fiber-optic cable plug used for RX and TX
connections.

Note
The PA-5EFL interfaces on a VIP are configured for 10 Mbps, half-duplex, for a maximum aggregate
bandwidth of 50 Mbps for half-duplex. Cisco Systems does not supply ST-type optical-fiber cables;
these cables are available commercially. For ST-type, multimode optical-fiber cable specifications and
transmission distance limitations and requirements, refer to the section
“IEEE 802.3 10Base-FL
Specifications” section on page 1-2
