How do fiber optic connectors Work?,The history of fiber optic communications is an entire book, since it took several generations to reach the state of the art today.

optical fiber is a thin cylindrical fiber made from plastic or glass, that is as small as one tenth of a human hair. A typical optical fiber for telecom is made up of three layers that are counted from the inside out: fiber core (diameter 8~10um) and cladding (diameter 130um) and buffer coating (diameter 900um).

Fiber core and cladding are made of glass or silica. Fiber Core and layers of cladding are used to keep the light inside the core and prevent it from leakage. Fiber buffer coating is created of plastic or acrylic and offers handling flexibility as well as physical protection to the fiber.

Optic fibers make use of an optical phenomenon called total internal reflection. When light is injected into the fiber from the end, it becomes kept inside the core without leaking outside and losing energy.

Then light is digitally modulated to show 1 and 0 , just as a computer. As such, information can be transferred from one location to another one, which could 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 work. What is a fiber optic connector and what is its purpose in the fiber optic telecommunications network?

In simple terms A fiber optic connector’s function is similar to an electric power supply that is used to connect light in one section that is optical to a different section of optical fiber.

Because optical fibers are tiny they require fiber optic connectors to be designed with extreme precision, with a scale that is 0.1um which is one hundredth of the human hair.

Fiber optic connectors connect two fibers from end to end to ensure that light is able to be transferred from one fiber to another without bounce off the interface and loss its signal.

In addition, fiber optic connectors provide cross connect flexibility for the telecommunications network. Thus, a complex computer network could be made modular and manageable.

Just like any other connectors that are used in electronic industry, electric industry and computer industry, many different types connected to fiber optic cables were created during the evolution of the fiber optic communication. Some of them once were extremely popular in the field but have now served their purpose and are disappearing.

The most popular fiber optic connectors in use today include SC, ST, LC, FC, MTRJ, SMA and a few of lesser-known ones. Sure you will see new connectors invented with the development of the industry.
