14 Safety and equipment care information
WARNING
Risk of eye injury
When inspecting a connector, ensure that light sources are off.
The light source used in fiber optic cables can damage your
eyes.
To avoid getting debris in your eyes, wear safety glasses when
working with the canned air duster.
To avoid eye irritation on contact, wear safety glasses when
working with isopropyl alcohol.
Procedure steps
Step Action
1 To remove or retract the shroud, do one of the following.
• On removable shroud connectors, hold the shroud on the top
and bottom at the letter designation, apply medium pressure,
and pull it free from the connector body. Do not discard the
shroud.
• On retractable shroud connectors, hold the shroud in its
retracted position.
2 Remove dust or debris by applying canned air to the cylindrical
and end-face surfaces of the connector.
3 Gently wipe the cylindrical and end-face surfaces of both ferrules
using a tissue saturated with optical-grade isopropyl alcohol.
4 Gently wipe the cylindrical and end-face surfaces with a dry
tissue.
ATTENTION
Do not let the IPA evaporate; wipe it dry immediately. Alcohols can
leave a residue that is difficult to remove.
5 Blow dry the connector surfaces with canned air.
6 Inspect the connector to ensure it is clean and undamaged.
7 Using care to not touch the clean ferrules, gently push the
shroud back onto the connector until it seats and locks in place.

Cleaning receptacles
Clean connector receptacles or ports so that the optical signal is minimally
attenuated by the connection.
