Optical fiber is a long thin, cylindrical fiber made of glass or plastic, smaller than one tenth of the human hair. A typical optical fiber for telecom is made up of three layers of cylindrical shape, arranged from the inside out: fiber core (diameter 810um), cladding (diameter of 125um) along with buffer coating (diameter 900um).
Fiber core and cladding is made of glass or silica. Fiber Core and Cladding layers combine to contain the light inside the core and prevent it from losing. Fiber buffer coating is created from acrylic or plastic and offers handling flexibility as well as physical protection to 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 without spilling out and wasting its energy.
Then, light is digitally modulated to show 1 and 0 , تركيب الياف stc just like a computer, so 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?
Now you understand how optical fibers operate. So what is the fiber optic connector? And what’s the purpose of the fiber optic network of telecommunications?
Simply put A fiber optic connector’s purpose is just like an electric power source, it is used to connect light in one part that is optical to another segment of optical fiber.
Since optical fibers are so small, fiber optic connectors have to be constructed with high precision, at the scale to 0.1um, which equals one hundredth the human hair.
Fiber optic connectors align two fibers 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 for the telecommunication network. Thus, a complex computer network can be modularized and simple to manage.
Like other connectors that are used in electric industry, electronic industry and computer industry, many different kinds of fiber optic connectors were created in the course of development of the fiber optic communications. Certain of them were very popular in the industry but have now served their purpose and are fading away.
The most popular fiber optic connectors in use today are SC, ST, LC, FC, MTRJ, SMA as well as a few other less popular ones. You will surely see new connectors developed with the progress of this industry.
