Optical fiber is a long thin, cylindrical fiber made of glass or plastic, that is as small as one tenth of human hair. A standard telecom optical fiber is composed of three cylindrical layers, counted from the inside out: fiber core (diameter 810um) and cladding (diameter of 125um) as well as buffer layer (diameter 9000um).
Fiber core and cladding are made of glass or silica. Fiber Core and Cladding layers work together to confine the light within the core and prevent it from 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 internal reflection. When light is in the fiber from the the end, it becomes confined inside the core not leaking out and losing energy.
Then, light is digitally modulated to show the numbers 1 and 0 like a computer, so information can be transferred from one location to another, 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 the way optical fibers function. What is an optical connector and what’s its function in the fiber optic network of telecommunications?
Simply put A fiber optic connector’s purpose is similar to that of an electric power supply, it connects light from one segment of optical fiber with another segment of optical fiber.
Since optical fibers are so small they require fiber optic connectors to be designed with extreme precision, and at a size to 0.1um that is just one centimeter of a human hair.
Fiber optic connectors align 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 provide cross-connect flexibility to the telecommunication network. So a complicated computer network can be modularized and simple to manage.
Similar to other connectors that are used in electronic industry, electric industry, or computer industry, numerous types of fiber optic connectors were developed during the evolution of the fiber optic communication. Some of them once were highly popular in the market and 40&l=thumbs&u=http://dalilico.tk/site-7835.html now have served their purpose and are disappearing.
The most widely used fiber optic connectors in use today are SC, ST, LC, FC, MTRJ, SMA as well as a few lesser-known ones. There are certain to be new connectors being developed as a result of the advancement of technology.
