Optical fiber is a long thin, cylindrical fiber made of glass or plasticthat is that is as small as one tenth of human hair. A typical optical fiber for telecom is made up of three layers that are counted inside out: fiber core (diameter 810um) and the cladding (diameter of 125um) and buffer coating (diameter 900um).
Fiber core and رقم الالياف البصرية stc cladding are made from glass or silica. The fiber core and the cladding layers combine to contain the light inside the core and prevent it from losing. Fiber buffer coating is created out of plastic or acrylic, and gives handling flexibility and physical protection to the fiber.
Optic fibers make use of an optical phenomenon known as internal reflection. When light is injected into the fiber from end face, it is confined inside the core without leaking outside and wasting its energy.
Then, light is digitally modified to indicate 1 and 0 , just as a computer. As such, data can be transmitted from one site to another site which may be from San Francisco all the way to New York.
What is a fiber optic connector and how do they work?
Now you know how optical fibers work. What is the fiber optic connector? And what is its purpose in a fiber optic telecommunication network?
In simple terms, a fiber optic connector’s purpose is just like an electric power source It relies on light to transmit from one section of optical fiber with another section of optical fiber.
Because optical fibers are small that fiber optic connectors need to be constructed with high precision, with a size of 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 in a way that light can travel from one fiber into another without bouncing off the interface , and thus 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 manageable.
Similar to other connectors that are used in electronic industry, electric industry, or computer industry, many different types and types of connectors for fiber optics were developed during the evolution of the fiber optic communication. Certain of them were highly popular in the market but they have since served their purpose and are becoming obsolete.
The most popular fiber optic connectors in use today include SC, ST, LC, FC, MTRJ, SMA and a few of others that are less well-known. There are certain to be new connectors being developed as a result of the development of the industry.
