Optic fiber is a thin cylindrical fiber that is made of glass or plasticthat is that is as small as one tenth of a human hair. A typical optical fiber for telecom comprises three layers of cylindrical shape, arranged inside out: fiber core (diameter 8x10um), cladding (diameter 125um) as well as buffer layer (diameter 900um).
Fiber core and cladding are made of glass or silica. The fiber core and the cladding layers combine to contain the light within the core and prevent it from losing. The fiber buffer coating is constructed of plastic or acrylic and provides handling flexibility and physical protection for the fiber.
Optic fibers make use of an optical phenomenon called total internal reflection. When light is injected into the fiber from one end, it’s contained within the core, without spilling out and wasting its energy.
Then, light is digitally modulated to represent 1 and 0 , just as a computer. As such, information can be carried from one place to another one, which could be from San Francisco all the way to New York.
What are fiber optic connectors and how do they work?
Now you understand how optical fibers work. What is an optical connector and what is its purpose in the fiber optic telecommunications network?
Put it simple, a fiber optic connector’s function is similar to an electric power supply, it is used to connect light in one segment that is optical to another segment of optical fiber.
Since optical fibers are so tiny, fiber optic connectors have to be made with high precision, at the size of 0.1um which is one hundredth of a human hair.
Fiber optic connectors align two fibers from end to end to ensure that light is able to move from one fiber to another without bouncing off the connector and Nehicharity.com/__media__/js/netsoltrademark.php?d=Sitesar.cf%2Fsite-653.html losing its signal.
Additionally, fiber optic connectors provide cross connect flexibility to the telecommunications network. So a complicated computer network can be modularized and easy to manage.
Just like any other connectors that are used in electronic industry, electric industry and computer industry, numerous kinds connected to fiber optic cables were created along the development of 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 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 developed with the advancement of technology.
