c. Check that the twisted pair connection meets dB loss limits and
cable specifications outlined in Chapter 2.

3.9.5 Connecting Fiber Optic Link Segments
Use TPIMs -F2/ -F3 to connect Fiber Optic Link segments. 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.
