Optical fiber is a long thin cylindrical fiber made from glass or plastic, smaller than one tenth of a human hair. A typical optical fiber for telecom comprises three cylindrical layers, counted from the inside out as fiber core (diameter 810um) and the cladding (diameter of 125um) as well as buffer layer (diameter 9000um).
The fiber core and cladding are made of glass or silica. Fiber Core and Cladding layers are used to keep the light within the core, without leaking. The fiber buffer coating is constructed 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 the end, it becomes contained within the core, without leaking outside and losing its energy.
Then, light is digitally modified to show 1 and 0 just like a computer, so information can be carried from one site to another one, which could be located from San Francisco all the way to New York.
What is a fiber optic connector and how do they work?
Now you understand Marillion.com/forum/index.php?thememode=mobile;redirect=http://dir.kootta.com/site-7637.html how optical fibers operate. So what exactly 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 an electric power plug It is used to connect light in one part of optical fiber to another section of optical fiber.
Because optical fibers are small that fiber optic connectors need to be constructed with high precision, and at a size to 0.1um, which equals one hundredth a human hair.
Fiber optic connectors connect two fibers from end to end so precisely that light can be transferred from one fiber to another without being bounced off of the connector and losing its signal.
Additionally, fiber optic connectors provide cross-connect flexibility to the telecommunications network. Thus, a complex computer network could be made modular and easy to manage.
Just like any other connectors utilized in the electronic industry, the electric industry, or computer industry, numerous kinds connected to fiber optic cables were created during the evolution of the fiber optic communications. Some of them once were extremely popular in the field and now have served their purpose and are disappearing.
The most widely used fiber optic connectors in use today comprise SC, ST, LC, FC, MTRJ, SMA and a few others that are less well-known. Sure you will see new connectors developed with the development of the industry.
