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

Specialty optical fiber is modified, usually by doping, for a specialized function.

Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber.

Fiber optic test equipment is used to detect the signal loss/change through a fiber optic cable

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 wiring accessories are used to connect, adapt, polish, repair, fiber and fiber optic cables.

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