Multi Core Fibre Optic Cable

A multi fiber cable optical fiber consists of a core and a cladding layer selected for total internal reflection due to the difference in the refractive index between the two.

Multi core fibre optic cable.

Multicore fibre optic cables multimode or multi core fibre comes in a variety of specifications ranging anywhere from two to dozens of cores. Multi mode optical fiber is a type of optical fiber mostly used for communication over short distances such as within a building or on a campus. Fiber cables rated at 10 gbps 40 gbps and 100 gbps are standard. Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate.

Because light can travel for much longer distances over a fiber cable without losing its strength the need for signal boosters is lessened. Pof is a newer plastic based cable which promises performance similar to glass cable on very short runs but at a lower cost. In practical fibers the cladding is usually coated with a layer of acrylate polymer or polyimide. Because of this the number of light reflections created as the light passes through the core increases creating the ability for more data to pass through at a given time.
