CTS 710 SONET Test Set User Manual

Appendix H: Changing Optical Port
Connectors
The following procedures are discussed in this appendix:
H Cleaning the Optical Ports
H Changing the Optical Port Connectors
Cleaning the Optical Ports
If the CTS 710 performance appears degraded, the optical fiber and
optical port may be dirty. Clean the fiber connector with a clean
cloth.
To clean an optical port:
1. Verify that the CTS 710 has been turned off with the principal
power switch on the rear panel.
2. Remove the four screws that attach the bulkhead connector to the
front panel (see Figure H–1).
3. Gently pull the bulkhead out of the unit and unscrew the fiber
connector. Be careful not to pull beyond the fiber slack.
4. Using a soft, lint-free cloth with a high-quality glass cleaner,
clean the tip of the fiber cable.
5. If available, use low-pressure compressed air or canned air to
blow any dirt out of the bulkhead connector. If compressed air is
not available, then the bulkhead will have to be taken apart and
cleaned. Refer to the Changing the Optical Port Connectors
procedure, on page H–2, for information about bulkhead
disassembly.
6. After cleaning the bulkhead, reconnect the fiber and install the
bulkhead. Be sure to reinstall the dustcap chain.
