Optic fiber is a thin cylindrical fiber that is made of glass or Extremaduraempresarial.juntaex.es/cs/c/document_library/find_file_entry?p_l_id=47702&noSuchEntryRedirect=https://sitesar.cf/site-653.html plastic, smaller than one tenth of a human hair. A typical optical fiber for telecom is made up of three layers of cylindrical shape, arranged inside out as fiber core (diameter 8~10um) as well as cladding (diameter 125um) along with buffer coating (diameter 90um).
Fiber core and cladding is made from glass or silica. The fiber core and the cladding layers combine to contain the light inside the core without losing. Fiber buffer coating is made out of plastic or acrylic, and offers handling flexibility as well as physical protection to the fiber.
Fiber optics employ an optical phenomenon known as internal reflection. When light is introduced into the fiber from its the end, it becomes kept inside the core not leaking out and wasting its energy.
Then, light is digitally modulated to show 1 and 0 , just like a computer, so information can be transferred from one site 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. So what is an optical connector and what is its purpose in a fiber optic telecommunication network?
Put it simple The fiber optic connector’s function is similar to an electric power source that connects light from one part of optical fiber to another segment that is optical.
Since optical fibers are so tiny that fiber optic connectors need to be designed with extreme precision, at the size that is 0.1um that is just one centimeter of the human hair.
Fiber optic connectors align two fibers from end to end to ensure that light is able to be transferred from one fiber to another without being bounced off of the interface , and thus losing its signal.
Additionally, fiber optic connectors provide cross-connect flexibility to the telecommunication network. Thus, a complex computer network could be made modular and easy to manage.
Similar to other connectors used in electric industry, electronic industry, or computer industry, many different kinds of fiber optic connectors were created during the evolution of the fiber optic communication industry. Certain of them were highly popular in the market but have now served their purposes and are disappearing.
The most popular fiber optic connectors that are used today are SC, ST, LC, FC, MTRJ, SMA and a few lesser-known ones. Sure you will see new connectors developed with the advancement of technology.
