OTDR Port Connection Quality

OTDR Port Connection Quality
When you run an OTDR test, the tester determines the
quality of OTDR port connection (Figure 7-10).
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 FT600 FiberInspector Pro Video Microscope, 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, which can hide faults near the OTDR port.
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.
