Optical fiber is a long thin cylindrical fiber that is made of glass or Marketsmartpartners.com/__media__/js/netsoltrademark.php?d=reid2703a.blogdal.com%2F20637472%2F5-simple-statements-about-optical-fiber-explained plastic, that is as small as one tenth of a human hair. A typical optical fiber for telecom is made up of three cylindrical layers, counted from the inside out as fiber core (diameter 810um) as well as cladding (diameter of 125um) along with buffer coating (diameter 900um).
The fiber core and cladding are composed of silica or glass. Fiber Core and Cladding layers combine to contain the light within the core, without leaking. Fiber buffer coating is made out of plastic or acrylic, and gives handling flexibility and physical protection to the fiber.
Fiber optics employ an optical phenomenon known as total internal reflection. When light is injected into the fiber from one end, it’s contained within the core, without spilling out and losing energy.
Then, light is digitally modulated to represent 1 and 0 , just like a computer, and information can be transferred from one place to another site which may be from San Francisco all the way to New York.
What are fiber optic connectors and what do they do?
Now you understand how optical fibers work. What is a fiber optic connector and what is its purpose in a fiber optic telecommunication network?
In simple terms The fiber optic connector’s job is similar to an electric power source, it relies on light to transmit from one section that is optical to another segment of optical fiber.
Since optical fibers are tiny they require fiber optic connectors to be made with high precision, with 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 move from one fiber to another without bounce off the connector and losing its signal.
Additionally the fact that fiber optic connectors offer cross-connect flexibility to the telecommunications network. Thus, a complex computer network can be modularized and manageable.
Like other connectors utilized in the electronic industry, electric industry, or computer industry, numerous types of fiber optic connectors were invented in the course of development of the fiber optic communication. Some of them once were highly popular in the market but have now served their purposes and are becoming obsolete.
The most well-known fiber optic connectors that are used today are SC, ST, LC, FC, MTRJ, SMA and a few of lesser-known ones. You will surely see new connectors developed with the advancement of technology.
