optical fiber is a thin cylindrical fiber made from plastic or glass, as tiny as one tenth of human hair. The standard optical fiber in telecom comprises three layers of cylindrical shape, arranged inside out: fiber core (diameter 8~10um) as well as cladding (diameter 125um) along with buffer coating (diameter 90um).
The fiber core and cladding are composed of silica or glass. The fiber core and the layers of cladding combine to contain the light within the core and http://fabtronic.co.uk/?URL=http://calcme.atwebpages.com/dir/site-942.html prevent it from leakage. The fiber buffer coating is constructed of plastic or acrylic and gives handling flexibility and physical protection to the fiber.
Optical fibers utilize an optical phenomenon called total internal reflection. When light is in the fiber from the end face, it is contained within the core, without spilling out and wasting its energy.
Then, light is digitally modulated to represent the numbers 1 and 0 like a computer, so information can be carried from one site to another, which could be located from San Francisco all the way to New York.
What are fiber optic connectors and what do they do?
You now know how optical fibers work. So what is the fiber optic connector? And what is its purpose in the fiber optic network of telecommunications?
Simply put, a fiber optic connector’s function is similar to that of an electric power supply It connects light from one segment of optical fiber to another section that is optical.
Because optical fibers are small that fiber optic connectors need to be constructed with high precision, at the size that is 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 so precisely that light can be transferred from one fiber to another without bouncing off the connector and losing its signal.
Besides fiber optic connectors, they provide cross connect flexibility for the telecommunication network. Therefore, a computer network that is complex could be made modular and simple to manage.
Like other connectors that are used in electric industry, electronic industry, or computer industry, many different kinds and types of connectors for fiber optics were created along the development of fiber optic communication. Certain of them were very popular in the industry but they have since been used for a variety of purposes, but are now disappearing.
The most popular fiber optic connectors in use today are SC, ST, LC, FC, MTRJ, SMA and a few other less popular ones. There are certain to be new connectors invented with the development of the industry.
