Item No.ITEM FOR INSPECTIONSubconJCIOBIClient
1Check the validity of the calibration certificate of the OTDR
machine.
2Check that a long launch lead cable is used. This will allow
the OTDR to settle down after the initial pulse and provides a
reference cable for testing the first connector on the cable.
(Note: Always start with the OTDR set for the shortest pulse width
for best resolution and a range at least twice (2) times the length
of the cable you are testing.)
3Check that the each end face of connector of the test cables is
clean and free from dirt prior to plug-in.
4Ensure that a launch lead cable is used to enable full
evaluation of the path
5Ensure to use correct mating adapter and fiber connector (where
applicable).
6Ensure that the Fiber optic cable has no active or power light
source connected on either end, before connecting the OTDR.
7Ensure that the set-up of OTDR is not set to auto-configuration
options enabled; else OTDR will struggle with the configuration of
the FFT sensor.
8Ensure that all testing on the Micro strain systems is
performed at 1550 nm with fiber refractive index of 1.4682.
9Ensure the distance setting at the OTDR is set to a distance
longer than the total expected length of the cable.
10Ensure to set the pulse width setting as necessary to slightly
increase the pulse width to allow for the excess losses from the
start and end sensors.
11Ensure to test the Fiber Optic cable in both directions, first
from the lead-in, then from the lead-out.
12Check that the fiber loss result meets the recommended typical
reading of 0.25dB/km and an increase margin of 0.02dB/Km is
acceptable.
14Check that the fusion splices losses must be less than 0.05dB
at a maximum.
15Check that the connector loss must be less than 0.5dB at
maximum.
16Ensure to make record and or document in every test
conducted.
