OTDR Connection Quality
OTDR Connection Quality
When you run an OTDR test, the tester determines the
quality of OTDR port connection (Figure 3-6).
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 3-7. 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.
The port connection quality rating is saved with OTDR
