Multi Core Fibre Optic Cable

In practical fibers the cladding is usually coated with a layer of acrylate polymer or polyimide.

Multi core fibre optic cable.

Pof is a newer plastic based cable which promises performance similar to glass cable on very short runs but at a lower cost. 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 mode links can be used for data rates up to 100 gbit s. Common configurations for everyday networking uses such as workplace comms infrastructure include 2 core fibre optic cable 8 core options and even 24 core varieties.

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. Because light can travel for much longer distances over a fiber cable without losing its strength the need for signal boosters is lessened. Fiber cables rated at 10 gbps 40 gbps and 100 gbps are standard. Multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber.

Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate.
