11 Testing |
11.1 Provisioning Tests |
Equipment should be tested from the source (or central office) to receiver at the time of provisioning to verify signal
continuity and acceptable loss limits. Use an optical power meter to verify signal continuity and determine whether
loss measurements are within specified local standards.
11.2 Troubleshooting Tests |
An optical power meter can be used to perform the first step in troubleshooting. A power meter designed for
measuring only dBm power levels is suitable for maintenance purposes.
For high attenuation:
•
Remove connector and reclean connector and adapter.
•
Verify cable ties are not too tight.
•
Maintain appropriate fiber bend radius. Make sure there are no sharp bends.
Once a fault is isolated to the installed cable link, an optical time domain reflectometer (OTDR) is needed. An
OTDR can locate fiber events and measure the losses attributable to cable, connectors, splices, and/or other
components. The graphical display of loss over a cable’s entire length provides the most revealing analysis and
documentation available on a cable link, commonly referred to as its signature trace. Corning recommends
performing an OTDR analysis to document the integrity of the cable system, locate and measure each event or
component, and uncover faults throughout the cable. Follow the instructions provided with the OTDR tester you are
using.
12 Maintenance and Repair Procedures |
12.1 Maintain the Housing
No routine maintenance of this product is required to keep it in operational order. In the event of loss of service or
low performance, test the connections as described in Section 10. Reenter the bottom chamber, if necessary, to
determine which components are defective.
12.2 Reenter the Housing
Use a 3/8-in can wrench to loosen the external security screw and then depress the access latches to open the
front cover.
12.3 Replace Components
Contact Corning Engineering Services at 1-800-743-2671 for instructions to repair or replace broken or defective
components.
