Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members.

Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device

Fiber optic receivers are instruments that convert light into electrical signals.

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss.

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output

Fiber optic test sources review the performance of a system by injecting light through the fibers

Fiber optic fault locators shine red laser light through jacketed fibers to identify breaks, bends, faulty connectors, splices and other causes of signal loss
