Optical fiber is a long thin, cylindrical fiber made of glass or plastic, as tiny as one tenth of human hair. A typical optical fiber for telecom is made up of three cylindrical layers, counted from the inside out: fiber core (diameter 8x10um) as well as the cladding (diameter 125um) as well as buffer layer (diameter 900um).
Fiber core and cladding is made from glass or silica. The fiber core and the cladding layers work together to confine the light inside the core without leakage. Fiber buffer coating is created out of plastic or acrylic, and offers handling flexibility as well as physical protection for 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 confined inside the core without spilling out and losing energy.
Then, light is digitally modulated to represent the numbers 1 and 0 like a computer, Arrowmakerinc.com/__media__/js/netsoltrademark.php?d=vb.3almc.com%2Fshowthread.php%3Ft%3D30095 (faicircolare.it) and data can be transmitted from one location to another one, which could be located 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. So what is a fiber optic connector and what’s its function in the fiber optic telecommunications network?
Put it simple, a fiber optic connector’s function is similar to that of an electric power supply, it relies on light to transmit from one section of optical fiber with another section that is optical.
Since optical fibers are small, fiber optic connectors have to be made with high precision, at the scale 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 bounce off the connector and losing its signal.
Besides fiber optic connectors, they provide cross-connect flexibility to the telecommunication network. So a complicated computer network can be modularized and manageable.
Just like any other connectors utilized in the electronic industry, electric industry and computer industry, many different types connected to fiber optic cables were developed during the evolution of the fiber optic communication. Certain of them were very popular in the industry but they have since served their purpose and are disappearing.
The most well-known fiber optic connectors that are used today are SC, ST, LC, FC, MTRJ, SMA as well as a few others that are less well-known. There are certain to be new connectors invented with the advancement of technology.
