Cleaning and Connecting Optical Fibers
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.

MPORTANT
The FTB-5800 module is particularly sensitive to unclean fibers. Your
results can be erroneous if your fiber is dirty. Verify the fiber end
with a portable fiber-optic microscope (for example, EXFO’s FOMS)
or fiber inspection probe (for example, EXFO’s FIP).
