Optical fiber is a long thin cylindrical fiber made from glass or plasticthat is that is as small as one tenth of the human hair. The standard optical fiber in telecom is made up of three layers that are counted from the inside out: fiber core (diameter 8~10um) as well as the cladding (diameter 130um) along with buffer coating (diameter 90um).
The fiber core and cladding are composed of silica or glass. Fiber Core and مندوب ألياف بصرية stc Cladding layers are used to keep the light inside the core, without leaking. Fiber buffer coating is made of plastic or acrylic and provides handling flexibility and physical protection for the fiber.
Optical fibers utilize an optical phenomenon known as internal reflection. When light is introduced into the fiber from its one end, it’s kept inside the core without spilling out and losing its energy.
Then light is digitally modulated to represent the numbers 1 and 0 like a computer, and data can be transmitted from one location to another site which may be from San Francisco all the way to New York.
What is a fiber optic connector and how do they function?
Now you understand how optical fibers work. What is an optical connector and what’s the purpose of the fiber optic network of telecommunications?
Put it simple, a fiber optic connector’s function is similar to an electric power plug, it is used to connect light in one segment of optical fiber to another segment that is optical.
Since optical fibers are so small, fiber optic connectors have to be made with high precision, and at a size that is 0.1um that is just one centimeter of the 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 bounce off the interface and loss its signal.
Besides the fact that fiber optic connectors offer cross connect flexibility for the telecommunication network. Therefore, a computer network that is complex can be modularized and manageable.
Like other connectors utilized in the electronic industry, the electric industry, and the computer industry, a variety of types and types of connectors for fiber optics were created in the course of development of the fiber optic communication. Certain of them were very popular in the industry and now have served their purposes and are fading away.
The most popular fiber optic connectors that are used today are SC, ST, LC, FC, MTRJ, SMA and a few of other less popular ones. Sure you will see new connectors being developed as a result of the advancement of technology.
