Fiber optic light guides are bundles of optical fibers used for the controlled deliver of light. They tend to be more rigid, and transmit well in both the visible and near-infrared (near-IR) regions of the electromagnetic spectrum.

Light guides conduct the flow of light from a light source to a point of use in areas that are too small or too hazardous to permit the installation of a light bulb. There are two basic types of light guides: liquid and fiber optic.

Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members. Fiber optic cables are used to transmit "light" data.

Fiber optic proximity sensors use fiber optic technology to detect the proximity of target objects.

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 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 switches route an optical signal without electro-optical and opto-electrical conversions.

Fiber optic receivers are instruments that convert light into electrical signals. They contain a photodiode semiconductor, signal conditioning circuitry, and an amplifier.

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

Fiber optic termination and splicing equipment includes tools or kits for cutting, finishing, positioning, aligning and joining fiber optic cables.

Fiber optic transmitters are devices that include an LED or laser source, and signal conditioning electronics, to inject a signal into fiber.

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors.

Fiber optic polarizers (FOP) are placed inline to improve the extinction characteristics of fiber optic cable. They allow the transmission of only one polarization, blocking light in unwanted polarization states.

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

Fiber optic power meters are instruments that measure the average power of a continuous light beam. They are used to test signal power in fiber optic networks.
