Caution
To prevent damage to the tester or cables under
test:

Do not connect the OTDR port to an optical source.
Doing so can cause damage to the OTDR receiver.

Do not connect the tester to an active network.
Doing so causes unreliable test results, can disrupt
network operations, and can cause damage to the
OTDR receiver.

Do not touch reflective surfaces (such as metal) to
the end of a fiber cable connected to the OTDR
when the OTDR is operating. An open fiber
connector endface has about a 4% reflection.
Holding a reflective surface near the connector
endface can cause more than a 4% reflection, which
can damage the photodetector in the OTDR.

Do not connect APC (angled physical contact)
connectors to the OptiFiber Pro OTDR ports. Do not
connect PC or UPC connectors to the OptiFiber Pro
HDR OTDR ports. Doing so can damage the port’s
endface.

Use proper cleaning procedures to clean all fiber
connectors before every use. Neglecting this step or
using improper procedures can cause unreliable test
results and may permanently damage the
connectors. See Chapter 7.

Use a video probe to periodically inspect the OTDR
connectors for scratches and other damage.

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.
