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.
The structure of a typical single-mode fiber. 1. Core 9 μm diameter 2. Cladding 125 μm dia. 3. Coating 250 μm dia. 4. Buffer or jacket 900 μm dia. Light propagating in a multi-mode fiber. The core of a conventional optical fiber is the part of the fiber that guides the light.
Some fiber optic cable versions are reinforced with aramid yarns or glass yarns as an intermediary strength member. In commercial terms, usage of the glass yarns are more cost-effective with no loss of mechanical durability. Glass yarns also protect the cable core against rodents and termites.
Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The standard G.651.1 defines the most widely used forms of multi-mode optical fiber.
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. The core and the cladding (which has a lower- refractive-index ) are usually made of high-quality silica glass, although they can both be made of ...
A common configuration is a four-pair Category 5 cable with two strands of multimode fiber optic cable. [12] The Xbox 360 used a "hybrid cable" to connect the console to either composite or component video inputs. [13] The "hybrid cable" used for the Xbox 360 carries composite, component and audio signals
