Optic fiber is a thin cylindrical fiber that is made of 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 of cylindrical shape, arranged inside out the fiber core (diameter 810um), cladding (diameter 130um) along with buffer coating (diameter 9000um).
Fiber core and cladding are made of glass or silica. Fiber Core and Cladding layers work together to confine the light within the core and prevent it from leaking. Fiber buffer coating is made of plastic or acrylic and http://dalilico.tk/site-7835.html provides handling flexibility and physical protection to the fiber.
Optic fibers make use of an optical phenomenon known as internal reflection. When light is in the fiber from the end face, it is confined inside the core not leaking out and losing energy.
Then light is digitally modulated to represent 1 and 0 , just as a computer. As such, information can be transferred from one place to another site which may 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 the fiber optic connector? And what is its purpose in the fiber optic telecommunications network?
In simple terms, a fiber optic connector’s function is just like an electric power supply that connects light from one part of optical fiber to another section of optical fiber.
Since optical fibers are so tiny, fiber optic connectors have to be constructed with high precision, at the scale of 0.1um, which equals one hundredth the human hair.
Fiber optic connectors connect two fibers from end to end in a way that light can be transferred from one fiber to another without bouncing off the interface and loss its signal.
Besides the fact that fiber optic connectors offer cross connect flexibility to the telecommunications network. Therefore, a computer network that is complex could be made modular and simple to manage.
Just like any other connectors used in electronic industry, the electric industry, and the computer industry, a variety of kinds connected to fiber optic cables were developed in the course of development of the fiber optic communication. Certain of them were very popular in the industry and now have served their purpose and are disappearing.
The most well-known fiber optic connectors in use today include SC, ST, LC, FC, MTRJ, SMA and a few of others that are less well-known. There are certain to be new connectors developed with the development of the industry.
