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

Fiber optic wiring accessories are used to connect, adapt, polish, repair, fiber and fiber optic cables. This area includes fiber optic consumables such as polish, swabs, wipes, etc.

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.

Fibre Channel products include hubs, directors, servers, adapters, etc

Fibre Channel connectors are high-speed connectors used in Fibre Channel systems

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

Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they can compute the distance to breaks or attenuation

Specialty optical fiber is modified, usually by doping, for a specialized function. It consists of one or more transparent fibers enclosed in a protective covering

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

Optical modulators vary the amplitude and phase of a light beam; e.g., from a laser or by sound waves

Electrical conduits and fittings are lengths of solid tubing used to house, protect, and cover electrical wiring and cables in power distribution systems.

Optical component accessories are used in the design or maintenance of optical components and systems

Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems
