• Avoid touching reflective surfaces (such as metal)
to the end of a fiber cable plugged into the OTDR
when the OTDR is operating. An open fiber
connector end face has about a 4% reflection.
Holding a reflective surface near the connector
end face may cause much greater than a 4%
reflection, which may damage the photodetector
in the OTDR.
• Read the instructions for splice machines before
using the OTDR to monitor splicing procedures.
The OTDR can interfere with the light injection
detection techniques used by some splicers.
