Connecting Fibre Optic Cables for Single-Mode Operations

1. Refer to Figure 34.

2. Attention:

v Ensure that each fibre optic cable is connected between the Receive connector

(note the symbol 1) of one optical extender and the Transmit connector (note

the symbol 3) of the optical extender at the other end of the fibre optic link.

v Before connecting fibre optic cables and devices, ensure that the end faces of

the cables are clean. If necessary, use a small cotton pad to apply a

fibre-cleaning fluid, such as IPA/D-1 Water Mix 106-17F, to the end faces.

Connect the fibre optic cables 2 to each optical extender 4.

Note: The fibre optic cables have:

v An inner connector with an alignment lug that engages a slot in the

connector of the optical extender

v An outer, bayonet (push-and-twist) connector that locks the cable to the

optical extender.

To connect a fibre optic cable:

a. Push it into the connector of the optical extender. As you push the cable,

use a twisting motion to ensure that the alignment lug engages the slot in

the connector of the optical extender.

b. Fasten the bayonet connector in the normal way.

If you cannot fasten the bayonet connector, disconnect the cable, and try

again.

3. Ensure that all fibre optic cables are correctly connected to the SSA adapter.

4. Attention: Excessive movement at connections in a fibre optic link might cause link

errors.

Ensure that the fibre optic cables are held tightly by cable ties to prevent strain and

movement at the optical extenders.
