Optical fiber is a long thin, cylindrical fiber made of glass or plasticthat is that is as small as one tenth of a human hair. A standard telecom optical fiber comprises three cylindrical layers, counted from the inside out: fiber core (diameter 8x10um) and cladding (diameter of 125um) and تركيب الياف بصرية buffer coating (diameter 90um).
Fiber core and cladding are made of glass or silica. The fiber core and the layers of cladding combine to contain the light inside the core and prevent it from leakage. The fiber buffer coating is constructed out of plastic or acrylic, and provides handling flexibility and physical protection for the fiber.
Fiber optics employ an optical phenomenon known as total internal reflection. When light is introduced into the fiber from its end face, it is contained within the core, without leaking outside and losing its energy.
Then light is digitally modulated to show the numbers 1 and 0 like a computer, and information can be carried from one site to another, which could be from San Francisco all the way to New York.
What are fiber optic connectors ? And how do they function?
You now know the way optical fibers function. So what is a fiber optic connector and what’s the purpose of the fiber optic network of telecommunications?
Simply put The fiber optic connector’s job is similar to that of an electric power source, it is used to connect light in one segment of optical fiber with a different section of optical fiber.
Since optical fibers are so small that fiber optic connectors need to be constructed with high precision, with a scale that is 0.1um, which equals one hundredth the human hair.
Fiber optic connectors align two fibers end to end to ensure that light is able to move from one fiber to another without bouncing off the connector and losing its signal.
Besides, fiber optic connectors provide cross connect flexibility to the telecommunication network. Therefore, a computer network that is complex can be modularized and simple to manage.
Just like any 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 during the evolution of the fiber optic communication industry. Certain types were once extremely popular in the field and now have served their purposes and are disappearing.
The most widely used fiber optic connectors in use today include SC, ST, LC, FC, MTRJ, SMA as well as a few others that are less well-known. Sure you will see new connectors being developed as a result of the advancement of technology.
