OTDR Connection Quality

When you run an OTDR test, the tester determines the
quality of OTDR port connection (Figure 7).
If the gauge is in the Poor range, you should clean the OTDR
port and the fiber connector. Use a video microscope, such as
the FiberInspector video probe, to inspect the port and fiber
connector for scratches and other damage. If a connector on
the tester is damaged, contact Fluke Networks for service
information.
A poor OTDR connection increases the connector's
deadzone, as shown in Figure 40 on page 100. The deadzone
can hide faults near the OTDR connector.
A poor connection also decreases the light available for
testing the fiber. The weakened test signal causes a noisier
trace, poor event detection, and decreased dynamic range.
