Cleaning and Connecting Optical Fibers
To connect the fiber-optic cable to the port:
1. Inspect the fiber using a fiber inspection microscope. If the fiber is clean,
proceed to connecting it to the port. If the fiber is dirty, clean it as explained
below.
2. Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
3. Carefully align the connector and port to prevent the fiber end from touching the
outside of the port or rubbing against other surfaces.
If your connector features a key, ensure that it is fully fitted into the port’s
corresponding notch.
4. Push the connector in so that the fiber-optic cable is firmly in place, thus
ensuring adequate contact.
If your connector features a screwsleeve, tighten the connector enough to firmly
maintain the fiber in place. Do not overtighten, as this will damage the fiber and
the port.
Note: If your fiber-optic cable is not properly aligned and/or connected, you
will notice heavy loss and reflection.
EXFO uses good quality connectors in compliance with EIA-455-21A standards.
To keep connectors clean and in good condition, EXFO strongly recommends
inspecting them with a fiber inspection probe before connecting them. Failure to do
so will result in permanent damage to the connectors and degradation in
measurements.

To ensure maximum power and to avoid erroneous readings:

Always clean fiber ends as explained below before inserting
them into the port. EXFO is not responsible for damage or errors
caused by bad fiber cleaning or handling.

Ensure that your patchcord has appropriate connectors. Joining
mismatched connectors will damage the ferrules.
