2-16 Connecting the Cables FCD-E1

To connect the main link and the sublink:
• Connect the main link and, when applicable, sublink cables to the connectors
corresponding to the interfaces in use.
Do not connect to both the balanced and unbalanced interfaces of the
same link!
• When using the balanced interfaces, connect the cable to the RJ-45
connectors designated MAIN E1 and/or SUB E1, respectively.
• When using the unbalanced interface, connect the cable to the two BNC
connectors of the appropriate interface:
 The BNC connectors of the main link interface are designated TX OUT
(transmit output) and RX IN (receive input).
 The BNC connectors of the sublink interface are designated RX OUT
(receive output) and TX IN (transmit input).
Pay attention to correct connection of the transmit and receive cables to the TX
and RX connectors of each interface.
The various user interface cables should be shielded, to improve EMC. FCD-E1A and
its interfaces will work well even if the cables are not shielded, but some radio
interference may occur.
Connecting the Fiber Optic Link
FCD-E1 units with fiber-optic main link interface may include Class 1 lasers.
For your safety:
Do not look directly into the optical connectors or the cable itself while the
FCD-E1 is operating.
The use of optical instruments with this product will increase eye hazard. Laser
power up to 1 mW at 1310 nm and 1550 nm could be collected by an optical
instrument.
The fiber optic E1 link interface is terminated in two ST or FC/PC connectors, in
accordance with order. The maximum allowable attenuation depends on the
interface option (refer to the Table 1-2).
Before connecting, clean the optical connectors using an approved solvent and dry
thoroughly using optical tissue.

To connect the fiber optic link:
1. Connect the optical connector designated TX to the transmit port of the local
FCD-E1 unit (transmit output connected to the receive input of the remote
unit).
2. Connect the optical connector designated RX to the receive port of the local
FCD-E1 unit (receive input, coming from the transmit output of the remote
unit).
Avoid sharp bends and twisting of the fiber optic cables.
