Optical fiber is a long thin cylindrical fiber that is made of plastic or glass, smaller than one tenth of a human hair. A typical optical fiber for telecom is composed of three cylindrical layers, counted in the inside as fiber core (diameter 810um) and cladding (diameter 130um) along with buffer coating (diameter 900um).
Fiber core and cladding are made of glass or silica. The fiber core and the layers of cladding work together to confine the light within the core without leakage. Fiber buffer coating is created of plastic or acrylic and provides handling flexibility and physical protection to the fiber.
Optical fibers utilize an optical phenomenon known as total internal reflection. When light is injected into the fiber from 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, and information can be carried from one place to another, which could be from San Francisco all the way to New York.
What are fiber optic connectors ? And how do they work?
Now you understand the way optical fibers function. What is an optical connector and what is its purpose in the fiber optic network of telecommunications?
Put it simple The fiber optic connector’s function is similar to that of an electric power source that is used to connect light in one part of optical fiber with another section that is optical.
Because optical fibers are small, fiber optic connectors have to be constructed with high precision, with a size that is 0.1um which is one hundredth of a human hair.
Fiber optic connectors are positioned to align two fibers from one end to the other to ensure that light is able to move from one fiber to another without bouncing off the interface , and Www.dalili.tk/site-7817.html thus losing its signal.
Besides the fact that fiber optic connectors offer cross-connect flexibility to the telecommunications network. So a complicated computer network can be modularized and simple to manage.
Similar to other connectors used in electric industry, electronic industry, and computer industry, numerous kinds connected to fiber optic cables were developed along the development of fiber optic communication. Certain types were once highly popular in the market but have now been used for a variety of purposes, but are now fading away.
The most widely used fiber optic connectors used nowadays include SC, ST, LC, FC, MTRJ, SMA and a few other less popular ones. There are certain to be new connectors being developed as a result of the progress of this industry.
