Fiber optic connections are vitally important. Optical fiber connectors terminate the end of an optical fiber to enable a quicker connection and disconnection. Connectors align the cores of fibers so light can pass through them.
Epoxy Connectors

The majority of connectors are epoxy/polish, where the fiber is glued into the connector with epoxy and the end is coated with a special polish. This type of connector provides the most reliable connection and is the lowest in cost. Epoxy connectors should set overnight, and any attempts to speed the curing process are not recommended.

Crimp Connectors
Crimp connectors hold the fiber in place without the use of glue, but result in a higher loss in efficiency and are more costly. The advantage with crimp connectors is a speedy install, as there is not setup time as with glue.

Tips
Both types of connectors use polish, which requires some special instructions. The smallest amount of dust, grease or skin oil can cause a poor connection. Make sure your hands and all the work space is as clean as possible. Clean connectors with lint-free wipes. Do not install connections near any heating or cooling vents. Do not overpolish, as too much polish creates a concave fiber surface, resulting in a poor connection. Polishing film attracts dust quickly and should be changed after a limited number of connections.
