What is the way that fiber optic connectors work? The history of fiber optic communications is an entire book, because it took several generations to get the industry today.

Optical fiber is a long thin cylindrical fiber that is made of glass or plastic, that is as small as one tenth of human hair. A typical optical fiber for telecom comprises three layers of cylindrical shape, arranged from the inside out as fiber core (diameter 810um) as well as cladding (diameter 130um) along with buffer coating (diameter 9000um).

Fiber core and cladding is made of glass or silica. Fiber Core and layers of cladding are used to keep the light within the core, without leaking. Fiber buffer coating is made out of plastic or acrylic, and provides handling flexibility and physical protection for the fiber.

Optic fibers make use of 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 wasting its energy.

Then, light is digitally modified to indicate 1 and 0 just as a computer. As such, data can be transmitted from one location to another one, 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. What is an optical connector and what’s its function in the fiber optic telecommunications network?

Simply put The fiber optic connector’s purpose is similar to that of an electric power source that relies on light to transmit from one section of optical fiber with a different section of optical fiber.

Since optical fibers are tiny they require fiber optic connectors to be constructed with high precision, and at a scale to 0.1um that is just one centimeter of the human hair.

Fiber optic connectors are positioned to align two fibers from end to end in a way that light can be transferred from one fiber to another without bounce off the connector and losing its signal.

Additionally the fact that fiber optic connectors offer cross-connect flexibility to the telecommunications network. So a complicated computer network can be modularized and easy to manage.

Similar to other connectors utilized in the electronic industry, electric industry and computer industry, numerous kinds of fiber optic connectors were created during the evolution of the fiber optic communication industry. Some of them once were very popular in the industry and now have served their purposes and are disappearing.

The most widely used fiber optic connectors in use today include SC, ST, LC, FC, ( wrote in a blog post) MTRJ, SMA and a few other less popular ones. Sure you will see new connectors invented with the advancement of technology.
