Fiber Optics Cable
Fiber optics cable is cable made of thin strands of glass. Digital information can be transmitted over these optically pure strands.
A fiber optics cable has the following parts:
- Core - the glass center of the fiber where light propagates and data is transmitted.
- Cladding - The material surrounding the core of the fiber; contains light in core while protecting against surface contaminant scattering.
- Buffer coating - The protective coating that is applied directly to the fiber.
Bundles contain numerous optical fibers and are protected by the cable's jacket (outer covering).
Fiber cable has many advantages over other types of cable. Fiber cable weighs less and has a smaller diameter than copper wire and uses less power while having a higher capacity for information. They are more suited for digital and light signal transmission and are not susceptible to EMI and RFI like traditional copper cables.
