Optical fiber is a long thin cylindrical fiber made from plastic or glass, that is as small as one tenth of the human hair. A typical optical fiber for مندوب ألياف بصرية stc (discover here) telecom comprises three cylindrical layers, counted in the inside as fiber core (diameter 8x10um) and cladding (diameter 125um) as well as buffer layer (diameter 900um).
Fiber core and cladding are made from glass or silica. Fiber Core and layers of cladding are used to keep the light inside the core without leakage. Fiber buffer coating is made from acrylic or plastic and gives handling flexibility and physical protection to the fiber.
Fiber optics employ an optical phenomenon known as total internal reflection. When light is injected into the fiber from end face, it is kept inside the core not leaking out and losing its energy.
Then light is digitally modulated to indicate 1 and 0 just like a computer, and information can be carried from one location to another, which could be from San Francisco all the way to New York.
What are fiber optic connectors ? And how do they function?
You now know the way optical fibers function. What is a fiber optic connector and what is its purpose in the fiber optic telecommunications network?
In simple terms The fiber optic connector’s job is just like an electric power plug, it relies on light to transmit from one section of optical fiber to a different section of optical fiber.
Since optical fibers are so small, fiber optic connectors have to be made with high precision, at the size that is 0.1um that is just one centimeter of the human hair.
Fiber optic connectors are positioned to align 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.
In addition, fiber optic connectors provide cross connect flexibility to the telecommunication network. Therefore, a computer network that is complex could be made modular and easy to manage.
Just like any other connectors that are used in electronic industry, the electric industry and the computer industry, a variety of kinds and types of connectors for fiber optics were created along the development of fiber optic communication industry. Certain of them were extremely popular in the field but they have since served their purpose 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 other less popular ones. There are certain to be new connectors being developed as a result of the advancement of technology.
