optical fiber is a thin cylindrical fiber that is made of plastic or Www.dalili.tk/site-7817.html glass, that is as small as one tenth of a human hair. The standard optical fiber in telecom is composed of three layers of cylindrical shape, arranged from the inside out the fiber core (diameter 810um), the cladding (diameter 130um) along with buffer coating (diameter 900um).
The fiber core and cladding are made of glass or silica. The fiber core and the cladding layers work together to confine the light inside the core, without leakage. Fiber buffer coating is made out of plastic or acrylic, and offers handling flexibility as well as physical protection for the fiber.
Fiber optics employ an optical phenomenon called total internal reflection. When light is introduced into the fiber from its one end, it’s confined inside the core without leaking outside and wasting its energy.
Then light is digitally modulated to represent 1 and 0 just as a computer. As such, information can be carried 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?
You now know how optical fibers operate. So what is the fiber optic connector? And what is its purpose in the fiber optic network of telecommunications?
Put it simple, a fiber optic connector’s job is similar to that of an electric power plug that relies on light to transmit from one section of optical fiber with another segment that is optical.
Because optical fibers are tiny that fiber optic connectors need to be constructed with high precision, with a scale that is 0.1um, which equals one hundredth a human hair.
Fiber optic connectors align two fibers from end to end to ensure that light is able to move from one fiber to another without bouncing off the connector and losing its signal.
Besides the fact that fiber optic connectors offer cross connect flexibility for the telecommunications network. Therefore, a computer network that is complex could be made modular and easy to manage.
Similar to other connectors that are used in electronic industry, the electric industry and computer industry, numerous types and types of connectors for fiber optics were developed in the course of development of the fiber optic communication. Some of them once were extremely popular in the field and now have served their purposes and are fading away.
The most popular fiber optic connectors that are used today comprise SC, ST, LC, FC, MTRJ, SMA as well as a few others that are less well-known. Sure you will see new connectors invented with the development of the industry.
