Optical fiber is a long thin cylindrical fiber made from plastic or glass, as tiny as one tenth of human hair. The standard optical fiber in telecom is composed of three layers that are counted from the inside out as fiber core (diameter 8x10um) and cladding (diameter 130um) along with buffer coating (diameter 9000um).

Fiber core and cladding are composed of silica or glass. The fiber core and the cladding layers work together to confine the light within the core without leakage. Fiber buffer coating is made from acrylic or plastic and provides handling flexibility and physical protection for the fiber.

Optical fibers utilize an optical phenomenon called total internal reflection. When light is in the fiber from the the end, it becomes contained within the core, without leaking outside and losing energy.

Then, light is digitally modulated to represent 1 and 0 just like a computer, so information can be transferred from one site to another site which may be located from San Francisco all the way to New York.

What are fiber optic connectors and what do they do?

Now you understand how optical fibers operate. So what is an optical connector and what’s its function in the fiber optic telecommunications network?

Put it simple The fiber optic connector’s purpose is similar to an electric power plug It relies on light to transmit from one part that is optical to another section that is optical.

Since optical fibers are so small, fiber optic connectors have to be designed with extreme precision, at the size to 0.1um, which equals one hundredth the human hair.

Fiber optic connectors are positioned to align two fibers from end to end so precisely that light can travel from one fiber into another without being bounced off of the interface , and thus losing its signal.

Additionally fiber optic connectors, they provide cross connect flexibility to the telecommunication network. Thus, a complex computer network could be made modular and simple to manage.

Like other connectors utilized in the electronic industry, the electric industry, and the computer industry, a variety of kinds connected to fiber optic cables were created along the development of fiber optic communications. Certain of them were very popular in the industry but have now served their purpose and are fading away.

The most well-known fiber optic connectors in use today include SC, ST, LC, FC, Www.dalil.info/site-13092.html (insurancemanonline.info) MTRJ, SMA and a few others that are less well-known. You will surely see new connectors being developed as a result of the advancement of technology.
