1. How do you repair a damaged fiber optic
cable
You have to locate the damaged area of the cable, this is
accomplished by an Optical Time Domain Reflectometer Based on the location of
the damage and what type of repair line level repair or depot maintenance level
either a splice or a pigtail assembly, and mechanical splices are under review
for approval and same redundant spare fiber or cable replacement can be
used.
2. How do you repair a fiber optic connector
You will need to perform a visual inspection of the connector
endface, using either a handheld optical microscope or a fiber optic video
probe, this procedure will determine the type of action needed to repair the
connector, If the connector only has minor damage, e.g: scratches, small chips,
or small pits, then re-polishing the connector will usually fix the problem if
the visual inspection determines that the connector is shattered or there is no
continuity then either a pigtail assembly will have to be spliced onto the
cable or the cable will need to be replaced utilizing a redundant spare fiber
for line level repair.
