Connecting Fibre Optic Cables for Multi-Mode Operations

1. Refer to Figure 30.

2. Attention:

v Ensure that each fibre optic cable is connected, via the multi-mode conditioner

3, between the Receive connector (note the symbol 1) of one optical

extender and the Transmit connector (note the symbol 7) 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.

Identify the yellow fibre 6 of the multi-mode conditioner.

3. Connect the yellow fibre to the Transmit connector (note the symbol 7)ofthe

optical extender.

4. Connect the orange fibre 2 to the Receive connector (note the symbol 1)of

the optical extender.

5. Repeat steps 3 and 4 for all the optical extenders that are installed on the 7133.

6. Find the uniters 4 that are supplied with the multi-mode conditioner.

7. Using the uniters, connect the main fibre optic cables 5 to the multi-mode

conditioner.

Note: The fibre optic cables have:

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

connector of the uniter

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

uniter.

To connect a fibre optic cable:

a. Push it into the uniter. As you push the cable, use a twisting motion to

ensure that the alignment lug engages the slot in the uniter.

b. Fasten the uniter to the multi-mode conditioner.
