optical fiber is a thin cylindrical fiber made from glass or plastic, Www.al3abfree.com/dir/site-1388.html smaller than one tenth of the human hair. A standard telecom optical fiber is composed of three layers of cylindrical shape, arranged from the inside out: fiber core (diameter 810um) and cladding (diameter of 125um) as well as buffer layer (diameter 90um).
Fiber core and cladding are made from glass or silica. Fiber Core and layers of cladding work together to confine the light within the core, without leaking. Fiber buffer coating is made of plastic or acrylic and gives handling flexibility and physical protection to the fiber.
Optic fibers make use of an optical phenomenon known as total internal reflection. When light is in the fiber from the end face, it is contained within the core, not leaking out and losing energy.
Then, light is digitally modified to show the numbers 1 and 0 like a computer, so information can be carried from one place to another site which may be from San Francisco all the way to New York.
What are fiber optic connectors and how do they work?
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 A fiber optic connector’s job is just like an electric power source It connects light from one segment of optical fiber with another segment that is optical.
Since optical fibers are so tiny they require fiber optic connectors to be constructed with high precision, at the scale to 0.1um which is one hundredth of the human hair.
Fiber optic connectors are positioned to align two fibers end to end in a way that light can travel from one fiber into another without bouncing off the interface and loss its signal.
Additionally fiber optic connectors, they provide cross connect flexibility to the telecommunication network. Therefore, a computer network that is complex could be made modular and simple to manage.
Similar to other connectors used in electronic industry, the electric industry and computer industry, many different kinds of fiber optic connectors were invented in the course of development of the fiber optic communication. Some of them once were extremely popular in the field but have now been used for a variety of purposes, but are now disappearing.
The most popular fiber optic connectors used nowadays are SC, ST, LC, FC, MTRJ, SMA as well as a few other less popular ones. You will surely see new connectors invented with the development of the industry.
