A label on the connector indicates the wiring (fibre type, connector type).
Table 2: Markings on the label
FO cable connector typeFO cable fibre type
ST = Straight tip (BNC connector)SM = Single-mode
SC = Subscriber connector (Snap-in connector)MM = Multi-mode
FO cables: connect
1. Install cables within the terminal compartment in a loop to achieve the highest
possible bending radius.
Figure 5: Wiring within in the terminal compartment
2. Measure and record the damping of the FO cables before connection.
3. Link connectors crosswise:
Output TX of actuator 1 to input RX of actuator 2
Input RX of actuator 1 to input TX of actuator 2

➥
Make sure that:
- the bayonet-type connection of connector type ST is properly engaged
- the straight tip of connector type SC fully mates the FO cable socket.
4. Protect unused FO cable connections against contamination or dust with pro-
tective caps/plugs supplied by the factory.
