Optical Fiber Cable Handling - Siemens SINUMERIK 840D Maintenance Manual

3.6 OPTICAL FIBER
CABLE HANDLING
OCTOBER 2005
Careful handling of Optical Fiber Cable:
1. Even though reinforcing cover used on the optical fiber code has enough mechani-
cal strength, be sure not to be damaged by heavy materials drop.
2. Detaching and attaching of optical connector should always be made by touching
connector. Optical fiber code should not be touched when replacement.
3. Optical connector is automatically locked with upper side lock levels after being
connected. It is impossible to pull out the connector without releasing the lock lev-
els.
4. Optical connector can not be connected oppositely. Be sure the connector direction
when connection is done.
5. Optical connector should be processed as follows before laying of optical fiber
cable.
Fix a reinforcing cover to a wire with hook or tension member by a tape. At
laying hook the wire or pull the tension member taking enough care that optical
connector does not receive pulling strength.
6. Reinforcing cover is fixed to cable lamp so that optical fiber cable could not weight
directly the connecting part of connector.
7. Notice that optical connector's chip is clear. The attached protect cap must be
always put on when optical connector is not used.
8. Remove dirt with a clear tissue or absorbent cotton (cotton with ethyl alcohol is
applicable). No other organic solvent than ethyl alcohol can be used.
