optical fiber is a thin cylindrical fiber made from plastic or glass, that is as small as one tenth of a human hair. The standard optical fiber in telecom comprises three layers of cylindrical shape, arranged inside out as fiber core (diameter 8~10um) as well as the cladding (diameter of 125um) as well as buffer layer (diameter 90um).
The fiber core and cladding are made from glass or silica. The fiber core and the Cladding layers combine to contain the light within the core without leakage. Fiber buffer coating is created out of plastic or acrylic, and gives handling flexibility and physical protection for the fiber.
Fiber optics employ an optical phenomenon known as total internal reflection. When light is injected into the fiber from the end, it becomes contained within the core, not leaking out and wasting its energy.
Then light is digitally modulated to show 1 and 0 just like a computer, and information can be transferred from one location to another one, which could be located from San Francisco all the way to New York.
What are fiber optic connectors and how do they work?
You now know how optical fibers operate. What is an optical connector and what is its purpose in the fiber optic telecommunications network?
Put it simple, a fiber optic connector’s purpose is similar to that of an electric power supply It connects light from one section that is optical to another segment of optical fiber.
Because optical fibers are small that fiber optic connectors need to be made with high precision, with a size that is 0.1um that is just one centimeter of a human hair.
Fiber optic connectors connect two fibers from end to end to ensure that light is able to travel from one fiber into another without bouncing off the interface , and thus losing its signal.
Additionally, fiber optic connectors provide cross-connect flexibility to the telecommunications network. Thus, a complex computer network could be made modular and manageable.
Similar to other connectors used in electronic industry, electric industry and the computer industry, a variety of types and types of connectors for fiber optics were created along the development of fiber optic communications. Some of them once were very popular in the industry and now have served their purpose and are becoming obsolete.
The most popular fiber optic connectors in use today are SC, ST, LC, FC, MTRJ, Продолжить (3) SMA and a few other less popular ones. Sure you will see new connectors developed with the progress of this industry.
