An opto-electronic instrument used to characterize an optical fiber.
Note 1: An OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber, light that is scattered back and reflected back. The intensity of the return pulses is measured and integrated as a function of time, and is plotted… (Read More →)

See transmittance.

A device that accepts an electrical signal as its input, processes this signal, and uses it to modulate an opto-electronic device, such as an LED or an injection laser diode, to produce an optical signal capable of being transmitted via an optical transmission medium.

The use of optical fiber networks to transport data frames from multiple data sources over an optical wavelength channel.

Any structure having the ability to guide optical energy.
Note: Optical waveguides may be (a) thin-film deposits used in integrated optical circuits (IOCs) or (b) optical fibers.

A material that rotates the plane of polarization of light that passes through it.

Synonym FOT.

Pertaining to any device that functions as an electrical-to-optical or optical-to-electrical transducer, or an instrument that uses such a device in its operation.
Note 1: Photodiodes, LEDs, injection laser diodes, and integrated optical circuit (IOC) elements are examples of opto-electronic devices commonly used in optical fiber communications.
Note 2: "Electro-optical" is often erroneously used as a synonym.
