If you are connecting the fibre optic cables for multi-mode operations, go to

“Connecting Fibre Optic Cables for Multi-Mode Operations” on page 17.

Connecting Fibre Optic Cables for Single-Mode Operations

1. Refer to Figure 8.

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 that is installed on

the 7133.

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.
