A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used.
Extrinsic fiber optic sensors use an optical fiber cable, normally a multi-mode one, to transmit modulated light from either a non-fiber optical sensor—or an electronic sensor connected to an optical transmitter. A major benefit of extrinsic sensors is their ability to reach otherwise inaccessible places.
The Telecommunications Industry Association's TIA-598-C Optical Fiber Cable Color Coding is an American National Standard that provides all necessary information for color-coding optical fiber cables in a uniform manner.
One countermeasure of fiber tapping is encryption, to make the intercepted data unintelligible to the thief. [4] Another is to deploy a fiber-optic sensor into the existing raceway, conduit, or armored cable. In this scenario, it can be detected if someone attempts to physically access the data (copper or fiber infrastructure).
Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and fiber-optic cables, or to cross-connect cables. Most optical fiber connectors are spring-loaded, so the fiber faces are pressed together when the connectors are mated.
SkyWrap fibre-optic cable installation. Optical attached cable (OPAC) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines. The attachment system varies and can include wrapping, lashing or clipping the fibre-optic cable to the host.
A cable reel trailer with conduit that can carry optical fiber Multi-mode optical fiber in an underground service pit An optical fiber cable consists of a core, cladding , and a buffer (a protective outer coating), in which the cladding guides the light along the core by using the method of total internal reflection .
Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks.
