Optical fiber is a long thin, cylindrical fiber made of glass or plastic, that is as small as one tenth of the human hair. A typical optical fiber for telecom is composed of three cylindrical layers, counted in the inside: fiber core (diameter 8x10um) and the cladding (diameter of 125um) along with buffer coating (diameter 90um).
Fiber core and cladding is composed of silica or glass. Fiber Core and Cladding layers work together to confine the light inside the core and prevent it from leaking. The fiber buffer coating is constructed 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 contained within the core, without leaking outside and losing energy.
Then light is digitally modulated to represent 1 and 0 , just like a computer, so information can be transferred from one site to another site which may be 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 operate. What is an optical connector and what is its purpose in the fiber optic telecommunications network?
Put it simple The fiber optic connector’s function is just like an electric power plug, it connects light from one section of optical fiber with another section of optical fiber.
Since optical fibers are so small that fiber optic connectors need to be constructed with high precision, at the scale to 0.1um, which equals one hundredth a human hair.
Fiber optic connectors connect two fibers end to end to ensure that light is able to be transferred from one fiber to another without bouncing off 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 could be made modular and easy to manage.
Similar to other connectors used in electric industry, Biosustainability.net/__media__/js/netsoltrademark.php?d=www.eyoon.gq%2Fsite-7839.html electronic industry, or the computer industry, a variety of kinds and types of connectors for fiber optics were invented in the course of development of the fiber optic communication. Certain types were once highly popular in the market and now have been used for a variety of purposes, but are now disappearing.
The most popular fiber optic connectors that are used today include SC, ST, LC, FC, MTRJ, SMA and a few lesser-known ones. Sure you will see new connectors invented with the progress of this industry.
