Optical fiber is a long thin cylindrical fiber made from plastic or glass, that is as small as one tenth of the human hair. A typical optical fiber for telecom is composed of three layers that are counted inside out the fiber core (diameter 8x10um), cladding (diameter of 125um) as well as buffer layer (diameter 90um).
Fiber core and cladding is made of glass or silica. The fiber core and the cladding layers work together to confine the light within the core without leakage. Fiber buffer coating is created out of plastic or acrylic, and gives handling flexibility and physical protection for the fiber.
Optical fibers utilize an optical phenomenon known as internal reflection. When light is in the fiber from the one end, it’s contained within the core, not leaking out and losing energy.
Then, light is digitally modulated 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 are fiber optic connectors and how do they function?
Now you know the way optical fibers function. What is an optical connector and what’s its function in the fiber optic telecommunications network?
Put it simple, a fiber optic connector’s job is just like an electric power plug It is used to connect light in one part of optical fiber with another section that is optical.
Because optical fibers are tiny they require fiber optic connectors to be designed with extreme precision, with a scale to 0.1um that is just one centimeter of the human hair.
Fiber optic connectors connect two fibers end to end to ensure that light is able to 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. So a complicated computer network could be made modular and manageable.
Similar to other connectors that are used in electronic industry, the electric industry and computer industry, many different kinds of fiber optic connectors were developed in the course of development of the fiber optic communication industry. Some of them once were highly popular in the market and مندوب ألياف بصرية stc الرياض now have served their purpose and are fading away.
The most popular fiber optic connectors used nowadays are SC, ST, LC, FC, MTRJ, SMA and a few others that are less well-known. Sure you will see new connectors developed with the advancement of technology.
