CONNECTORS / TERMINATIONS WITH FIBER GLOSSARY (8)

　　Plenum Cable: Cable made of fire-retardant material that meets electrical code requirements (UL 910) for low smoke generation and installation in air space.

　　Receiver: A device that detects an optical signal and converts it into an electrical form usable by other devices.

　　Refraction: The bending of light as it passes between materials of different refractive index.

　　Riser: A pathway for indoor cables that passes between floors, normally in a vertical shaft or space. Also a fire-code rating for indoor cable.

　　Simplex: Single element (e.g., a simplex connector is a single-fiber connector).

　　Simplex Cable: A term sometimes used for single-fiber cable.

　　Single Mode: Containing only one more. When dealing with lasers, beware of ambiguities because of the difference between transverse and longitudinal modes. A type of low-loss optical waveguide with a very small core (2.9 microns). It requires a laser source for input signals due to the very small entrance aperture.

　　Single Mode Fiber (SMF): A small-core optical fiber through which only one mode will propagate. The typical diameter is 8.9 microns.

　　Tight Buffer: A material tightly surrounding a fiber in a cable, holding it rigidly in place.

　　Tight Buffered Cable: A protective coating extruded tightly over fiber for mechanical and environmental protection. The coating material is either nylon or PVC. This buffering offers excellent physical and flexing properties, but higher micro-bending sensitivity.
