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.
Multi core fibre optic cable.
Multi mode links can be used for data rates up to 100 gbit s.
Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate.
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.
Fiber optics support a higher capacity the amount of network bandwidth a fiber cable can carry easily exceeds that of a copper cable with similar thickness.
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.
Multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber.
In practical fibers the cladding is usually coated with a layer of acrylate polymer or polyimide.
Multicore fibre optic cables multimode or multi core fibre comes in a variety of specifications ranging anywhere from two to dozens of cores.
