Optical fiber is a long thin cylindrical fiber made from plastic or glass, smaller than one tenth of a human hair. A typical optical fiber for telecom is made up of three layers that are counted from the inside out the fiber core (diameter 810um) and cladding (diameter of 125um) and buffer coating (diameter 9000um).
The fiber core and cladding are made of glass or silica. Fiber Core and cladding layers are used to keep the light within the core, without leaking. The fiber buffer coating is constructed from acrylic or plastic and provides handling flexibility and physical protection to the fiber.
Optic fibers make use of an optical phenomenon known as total internal reflection. When light is in the fiber from the the end, it becomes confined inside the core without leaking outside and losing energy.
Then, light is digitally modified to show 1 and 0 , رقم الالياف البصرية stc just as a computer. As such, information can be carried from one location 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 how optical fibers operate. So what exactly 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 similar to that of an electric power plug It is used to connect light in one part of optical fiber with a different section that is optical.
Because optical fibers are tiny they require fiber optic connectors to be made with high precision, with a scale to 0.1um that is just one centimeter of a human hair.
Fiber optic connectors are positioned to align two fibers from one end to the other so precisely that light can travel from one fiber into another without being bounced off of the interface and loss its signal.
Besides, fiber optic connectors provide cross-connect flexibility to the telecommunication network. Therefore, a computer network that is complex can be modularized and manageable.
Similar to other connectors utilized in the electronic industry, electric industry, and computer industry, many different kinds of fiber optic connectors were created along the development of fiber optic communication industry. Some of them once were highly popular in the market but they have since been used for a variety of purposes, but are now disappearing.
The most popular fiber optic connectors used nowadays are SC, ST, LC, FC, MTRJ, SMA and a few others that are less well-known. There are certain to be new connectors invented with the advancement of technology.
