Inspect the ferrule for signs of damage, for example scratches, cracks, or damaged guide
holes (badly worn or out-of-round).
Note — Do not use the device if there is damage.
Using the inspection kit, inspect the connector.
If the connector does not pass acceptance criteria in
device inspections", clean the connector (see Procedure
connectors").
Reconnect the connector and receptacle, and check for proper function.
Note 1 — Do not use optical devices that do not function properly.
Note 2 — In a fiber distribution network, it is an industry best practice
to use APC-based connections or spliced connections to avoid any
potential network problems. Nokia recommends that the unused ports
of splitters be terminated into an APC-based connector.
STOP. This procedure is complete.
Clean the fiber optic receptacles
Ensure that the receptacle has been inspected.
Clean the receptacle using an optical grade dry stick cleaner (swab) with a tightly wrapped
tip (1.25 mm, 2.50 mm, and 4.0 mm).
i Insert the stick in the receptacle and gently rotate it, making three full rotations and
using a lifting/plucking motion each time you stop to re-grip the stick.
ii Use a new stick for each port.
iii Re-inspect the receptacle.
