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 is composed of three layers of cylindrical shape, arranged in the inside the fiber core (diameter 8~10um), Rampe.com/__media__/Js/netsoltrademark.php?d=Www.dalil.info%2Fsite-13092.Html the cladding (diameter 125um) along with buffer coating (diameter 90um).
The fiber core and cladding are made from glass or silica. Fiber Core and cladding layers combine to contain the light inside the core, without leaking. Fiber buffer coating is created of plastic or acrylic and gives handling flexibility and physical protection for the fiber.
Optic fibers make use of an optical phenomenon known as total internal reflection. When light is in the fiber from the the end, it becomes confined inside the core not leaking out and losing its energy.
Then, light is digitally modulated to indicate the numbers 1 and 0 like a computer, and data can be transmitted from one site to another, which could be from San Francisco all the way to New York.
What is a fiber optic connector and what do they do?
Now you understand how optical fibers work. So what exactly is a fiber optic connector and what is its purpose in a fiber optic telecommunication network?
In simple terms The fiber optic connector’s job is similar to an electric power supply, it connects light from one segment of optical fiber with a different section that is optical.
Since optical fibers are so tiny that fiber optic connectors need to be designed with extreme precision, and at a size to 0.1um, which equals one hundredth the human hair.
Fiber optic connectors align two fibers from end to end in a way that light can travel from one fiber into another without bouncing off the connector and losing its signal.
Besides fiber optic connectors, they provide cross connect flexibility to the telecommunications network. So a complicated computer network could be made modular and manageable.
Just like any other connectors utilized in the electric industry, electronic industry and computer industry, many different kinds of fiber optic connectors were developed in the course of development of the fiber optic communication. Some of them once were extremely popular in the field and now have served their purposes and are becoming obsolete.
The most well-known fiber optic connectors that are used today include SC, ST, LC, FC, MTRJ, SMA and a few of others that are less well-known. You will surely see new connectors developed with the progress of this industry.
