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 transceivers include both a transmitter and a receiver in the same component

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 amplifiers re-amplify an attenuated signal without converting the signal into electrical form

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

Fiber optic circulators are nonreciprocal devices that direct a light signal from one port, via a fiber optic line, to another sequentially
