A patch panel where fiber-optic connectors are mounted.

An Ethernet fiber-optic connection method intended for connection of repeaters.

Used to splice outside plant cable to the backside of a fiber-optic patch panel.

Test procedures outlined in the EIA-RS-455 standards.

A communications scheme whereby electrical data is converted to light energy and transmitted through optical fibers.

A long, thin strand of transparent material (glass or plastic), which can convey electromagnetic energy in the optical waveform longitudinally by means of internal refraction and reflection.

Fibre optics – light transmission through optical fibers for communication and signaling.

Also known as IEC320 C7/ C8

Type of IEC connector used for Power supply. (See C7/ C8)

A fiber-optic cable with a strong supporting member incorporated for use in aerial installations. See also messenger cable.

Nonconducting components cabled with insulated conductors or optical fibers to impart flexibility, tensile strength, roundness, or a combination of all three.

A device that blocks certain wavelengths to permit selective transmission of optical signals.

Material, device, or collection of parts installed in a cable pathway (such as a conduit or riser) at a fire-rated wall or floor to prevent passage of flame, smoke, or gases through the rated barrier.

Also called fish cord. A tool used by electricians to route new wiring through walls and electrical conduit.

The average number of times a particular cable or type of cable can bend before breaking.
