optical fiber is a thin cylindrical fiber made from glass or plastic, smaller than one tenth of a human hair. The standard optical fiber in telecom comprises three layers that are counted from the inside out: fiber core (diameter 810um), cladding (diameter 125um) and buffer coating (diameter 9000um).
Fiber core and cladding is composed of silica or glass. The fiber core and the layers of cladding combine to contain the light inside the core and prevent it from leaking. Fiber buffer coating is created from acrylic or plastic and gives handling flexibility and physical protection for the fiber.
Optical fibers utilize an optical phenomenon known as internal reflection. When light is introduced into the fiber from its end face, it is kept inside the core not leaking out and losing energy.
Then, light is digitally modified 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 is a fiber optic connector and how do they work?
You now know the way optical fibers function. What is a fiber optic connector and what’s its function in the fiber optic telecommunications network?
Simply put A fiber optic connector’s purpose is just like an electric power source It relies on light to transmit from one part of optical fiber to another section of optical fiber.
Since optical fibers are small they require fiber optic connectors to be designed with extreme precision, at the size of 0.1um that is just one centimeter of the human hair.
Fiber optic connectors are positioned to align two fibers from one end to the other in a way that light can be transferred from one fiber to another without bouncing off the interface and loss its signal.
In addition the fact that fiber optic connectors offer cross-connect flexibility to the telecommunications network. Thus, a complex computer network can be modularized and easy to manage.
Similar to other connectors used in electronic industry, electric industry, and the computer industry, a variety of kinds of fiber optic connectors were invented in the course of development of the fiber optic communication. Certain of them were extremely popular in the field and الياف stc now have served their purposes and are fading away.
The most well-known fiber optic connectors used nowadays include SC, ST, LC, FC, MTRJ, SMA as well as a few other less popular ones. You will surely see new connectors being developed as a result of the progress of this industry.
