Optic fiber is a thin cylindrical fiber that is made of plastic or glass, as tiny as one tenth of a human hair. A standard telecom optical fiber comprises three layers of cylindrical shape, arranged inside out the fiber core (diameter 8~10um) and the cladding (diameter 130um) as well as buffer layer (diameter 90um).
Fiber core and cladding is made from glass or silica. The fiber core and Dalilico.tk/site-7835.html the cladding layers combine to contain the light inside the core and prevent it from leakage. Fiber buffer coating is made from acrylic or plastic and gives handling flexibility and physical protection for the fiber.
Optical fibers utilize an optical phenomenon known as total internal reflection. When light is injected into the fiber from one end, it’s confined inside the core without leaking outside and wasting its energy.
Then light is digitally modulated to indicate the numbers 1 and 0 as a computer. As such, information can be carried from one place to another, which could be located from San Francisco all the way to New York.
What is a fiber optic connector and how do they function?
Now you know the way optical fibers function. So what is an optical connector and what’s its function in the fiber optic network of telecommunications?
Put it simple, a fiber optic connector’s function is similar to that of an electric power plug, it is used to connect light in one section that is optical to another segment of optical fiber.
Since optical fibers are tiny that fiber optic connectors need to be constructed with high precision, with a size that is 0.1um, which equals one hundredth a human hair.
Fiber optic connectors are positioned to align two fibers from one end to the other so precisely that light can travel from one fiber into another without bouncing off the connector and losing its signal.
In addition fiber optic connectors, they provide cross-connect flexibility to the telecommunication network. Thus, a complex computer network can be modularized and easy to manage.
Similar to other connectors that are used in electronic industry, the electric industry and computer industry, numerous kinds connected to fiber optic cables were created along the development of fiber optic communication. Some of them once were highly popular in the market but they have since served their purposes and are fading away.
The most widely used fiber optic connectors that are used today include SC, ST, LC, FC, MTRJ, SMA as well as a few lesser-known ones. Sure you will see new connectors being developed as a result of the advancement of technology.
