5EFL Port Adapter Multimode Fiber-Optic Cable and Receptacles
The interface connectors on the 5EFL port adapter are five pairs of (ST) 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 6 shows the ST fiber-optic cable plug used for RX and
TX connections.

Note The 5EFL interfaces on a VIP2 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” on page 7.
VIP2 and the 5EFL Port Adapter
This section describes the 5EFL port adapter and its use with the VIP2.
The following sections provide additional information specific to the 5EFL port adapter and its use
on the VIP2 in Cisco 7000 series and Cisco 7500 series routers:
