TEST PROCEDURES
STEP 1 – CAPTURE ENDFACE IMAGES
Fiber endfaces must be inspected separately by a fiber videoscope
capable of:
– capturing endface images in either
.JPG
or
.BMP
format, and
– downloading the images to a PC.
NOTE: Videoscopes are available for purchase from OWL, but any
vendor’s videoscope can be used.
HELPFUL TIPS TO STAY ORGANIZED
– inspect the fiber ends in the same order as the fibers will be tested
– name the endface images similarly to the fibers to be tested
– store the images on the PC in an easy location to remember
STEP 2 – RUN OTDR TRACES
Run OTDR tests to characterize the network and measure the length of
the fiber link.
NOTE: OTDR traces are required for Tier 2 certification
For questions about testing fibers with the OTDR, see the OTDR MODE
section.
In FULL MODE, OTDR traces are taken as a part of the process.
In CERT MODE, OTDR traces must be acquired separately.
STEP 3 – CERTIFY THE CABLING
Measure the end-to-end loss with a power meter and light source for
PASS/FAIL testing (also referred to as Tier 1 certification).
Cable certification can be done with either CERT or FULL mode.
