4.3 CONNECTING FIBER OPTIC CABLE

Use the TPIM-F2/ F3 to connect fiber optic cable. When connecting a
fiber optic link segment to the TPIM-F2 or TPIM-F3 consider the
following:
• Fiber optic link segments with ST connectors attach to ST ports much
like BNC connectors attach to BNC ports. The connector is inserted
into the port with the alignment key on the connector inserted into the
alignment slot on the port. The connector is then turned to lock it
down.
• The physical communication link consists of two strands of fiber optic
cabling. The Transmit strand (Tx) at one end connects to the Receive
(Rx) port at the other end, and vice versa.
• It is recommended that you label fiber optic cable to indicate which
end of a fiber strand connects to a Receive port and which end connects
to Transmit port. By using such a labeling scheme, you can eliminate
the possibility of connecting devices incorrectly.
Dust, dirt, and other contaminants on the ends of the fiber optic
!
strands may create data-transmissions problems. If the ends
become dirty, clean them with isopropyl alcohol using a soft,

clean, lint-free cloth.
To connect a fiber optic link segment to the TPIM-F2 /-F3:
1. Remove the protective plastic covers from the fiber optic ports on the
module and from the ends of the fiber strand connectors.
2. Attach a fiber strand to the TPIM-F2/-F3's Receive port (labeled Rx)
and attach the other fiber strand to the TPIM-F2/-F3's Transmit port
(labeled Tx) as shown in Figure 4-7.
