Glossary

An optoelectronic circuit that converts an electronic signal into an optical signal.

Any structure that can guide light; the optical waveguide is a nonconductive material with a central core of optically transparent material (usually silica glass) surrounded by a transparent cladding material that has a lower refractive index than the core.

An assembly consisting of one or more optical fibers. These optical fibers are thin glass or plastic filaments used for the transmission of information via light signals. The individual optical fibers are the signal carrying part of a fiber-optic cable. See also single-mode fiber and multimode fiber.

A mechanical media termination device designed to align and join two duplex connectors.

A mechanical media termination device designed to transfer optical power between two pairs of optical fibers.

The process which follows a drive test of a given Cluster and which is intended to make adjustments to the performance of a site or sites to improve the corresponding cluster coverage and/or capacity.

Any device that uses or responds to optical power in its internal operation.

ORL is a ratio expressed in decibels. The reflection is caused by a component or an assembly.

A model defined by the ISO to categorize the process of communication between computers in terms of seven layers. See also International Organization for Standardization.

Typically used outside of the wire center but also may be routed into the CEF. Since OSP cables are more flammable than premises (indoor) cables, the distance of penetration into the building must be limited.

A device used to test a fiber-optic link, including the optical fiber and connectors, by launching an optical signal (light pulse) through the link and measuring the amount of energy that is reflected back. The OTDR is a troubleshooting device that can pinpoint faults throughout a fiber-optic link.

A metallic or nonmetallic box mounted within a wall, floor, or ceiling used to hold outlet, connector, or transition devices.

A metallic or nonmetallic box mounted within a wall, floor, or ceiling used to hold outlet, connector, or transition devices.

The useful signal or power delivered by a circuit or device.
