optical fiber is a thin cylindrical fiber that is made of plastic or glass, that is as small as one tenth of human hair. A standard telecom optical fiber is made up of three layers of cylindrical shape, Hideyou.me/redir.php?site=https://vb.3almc.com/showthread.php?t=30095 arranged from the inside out the fiber core (diameter 8~10um), the cladding (diameter 125um) and buffer coating (diameter 9000um).
The fiber core and cladding are made of glass or silica. Fiber Core and layers of cladding work together to confine the light inside the core without leakage. Fiber buffer coating is made out of plastic or acrylic, and gives handling flexibility and physical protection for the fiber.
Fiber optics employ an optical phenomenon known as total internal reflection. When light is introduced into the fiber from its end face, it is confined inside the core without leaking outside and losing its energy.
Then light is digitally modulated to represent 1 and 0 , just like a computer, so data can be transmitted from one location to another, which could be located from San Francisco all the way to New York.
What is a fiber optic connector and how do they work?
You now know how optical fibers operate. So what exactly is the fiber optic connector? And what’s its function in the fiber optic telecommunications network?
Simply put A fiber optic connector’s purpose is similar to that of an electric power supply, it relies on light to transmit from one segment that is optical to a different section of optical fiber.
Since optical fibers are so small that fiber optic connectors need to be made with high precision, at the scale to 0.1um which is one hundredth of the human hair.
Fiber optic connectors connect two fibers from one end to the other so precisely that light can travel from one fiber into another without being bounced off of the interface , and thus losing its signal.
In addition fiber optic connectors, they provide cross-connect flexibility to the telecommunication network. So a complicated computer network can be modularized and easy to manage.
Like other connectors utilized in the electric industry, electronic industry, or computer industry, numerous types connected to fiber optic cables were developed in the course of development of the fiber optic communication industry. Certain types were once extremely popular in the field but have now served their purpose and are disappearing.
The most popular fiber optic connectors in use today are SC, ST, LC, FC, MTRJ, SMA and a few others that are less well-known. There are certain to be new connectors being developed as a result of the development of the industry.
