optical fiber is a thin cylindrical fiber made from glass or plastic, that is as small as one tenth of the human hair. A standard telecom optical fiber is composed of three cylindrical layers, counted from the inside out the fiber core (diameter 8x10um) as well as the cladding (diameter 130um) along with buffer coating (diameter 9000um).
Fiber core and cladding are made from glass or silica. The fiber core and the layers of cladding are used to keep the light within the core and prevent it from losing. Fiber buffer coating is created out of plastic or acrylic, and offers handling flexibility as well as physical protection to the fiber.
Optical fibers utilize an optical phenomenon known as total internal reflection. When light is injected into the fiber from the end, it becomes confined inside the core without spilling out and wasting its energy.
Then light is digitally modulated to represent 1 and 0 , just like a computer, and information can be carried from one place to another one, which could be from San Francisco all the way to New York.
What are fiber optic connectors and how do they work?
You now know the way optical fibers function. So what exactly is the fiber optic connector? And what is its purpose in the fiber optic network of telecommunications?
Simply put A fiber optic connector’s purpose is just like an electric power source, it is used to connect light in one part of optical fiber to another segment of optical fiber.
Because optical fibers are small they require fiber optic connectors to be designed with extreme precision, and at a scale of 0.1um, which equals one hundredth a human hair.
Fiber optic connectors are positioned to align two fibers from one end to the other to ensure that light is able to travel from one fiber into another without bouncing off the connector and losing its signal.
Besides, fiber optic connectors provide cross-connect flexibility to the telecommunications network. Therefore, a computer network that is complex can be modularized and easy to manage.
Similar to other connectors used in electric industry, electronic industry and تركيب الياف بصرية stc computer industry, many different types and types of connectors for fiber optics were invented during the evolution of the fiber optic communications. Certain types were once extremely popular in the field but they have since been used for a variety of purposes, but are now becoming obsolete.
The most popular fiber optic connectors used nowadays comprise 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 progress of this industry.
