ABLING

To cable the 10BASE-FL module:

Remove the protective plastic covers from the
module’s fiber optic ports and from the ends of the
connectors on each fiber strand.

Locate the fiber attached to the receiver of the
remote 10BASE-FL transceiver/system and connect
it to the selected transmitter port on the module.

Locate the fiber attached to the transmitter of the
remote 10BASE-FL receiver/system and connect it to
the selected receiver port on the module.

Repeat steps 1 through 3 for the remaining ports.

Figure 4-12

shows the cabling of the 10BASE-FL

module using 10BASE-FL cabling.

10BASE-2 (BNC) Module

This section contains information on the common
10BASE- 2 (BNC) configuration and how to cable
the 10BASE- 2 (BNC) media option.

10BASE-2 (BNC) Configuration

Figure 4-13

illustrates a sample 10BASE-2 (BNC)

configuration. Your configuration may have different
quantities and types of devices than pictured in this
example.

Figure 4-13

shows an Ethernet module with

10BASE-2 (BNC) connectors attached to a coaxial
cabling segment. In this example, network segments
are using cable that conforms to the IEEE 802.3
Type 10BASE-2 specification.
