Terminating Optical Fiber
Fiber optic cable must be terminated in order to connect one sensor cable to another
or to connect sensor cable to the APU. Terminating cable circumvents the need for
permanently fusion splicing fiber segments together. Any cable connecting to the
APU must be terminated with ST-type connectors.

Following termination, fiber optic cable segments can be joined together using a feed
through coupler (also sometimes referred to as a "mating sleeve").
