Optical fiber is a long thin cylindrical fiber made from glass or plastic, as tiny as one tenth of a human hair. The standard optical fiber in telecom is composed of three layers that are counted in the inside the fiber core (diameter 8x10um) as well as the cladding (diameter 125um) along with buffer coating (diameter 90um).
Fiber core and cladding is composed of silica or glass. Fiber Core and Cladding layers are used to keep the light inside the core, without leaking. Fiber buffer coating is created of plastic or acrylic and offers handling flexibility as well as physical protection for the fiber.
Optical fibers utilize an optical phenomenon known as total internal reflection. When light is injected into the fiber from end face, it is kept inside the core not leaking out and losing energy.
Then, light is digitally modulated to show 1 and 0 just like a computer, so data can be transmitted from one site to another site which may be located from San Francisco all the way to New York.
What are fiber optic connectors and what do they do?
Now you understand 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 function is similar to an electric power source, it connects light from one section of optical fiber to a different section of optical fiber.
Since optical fibers are so small they require fiber optic connectors to be constructed with high precision, with a scale to 0.1um, which equals one hundredth a human hair.
Fiber optic connectors align two fibers end to end to ensure that light is able to move from one fiber to another without being bounced off of the connector and losing its signal.
In addition, fiber optic connectors provide cross connect flexibility to the telecommunications network. Therefore, a computer network that is complex can be modularized and simple to manage.
Like other connectors that are used in electric industry, electronic industry, or computer industry, many different types and types of connectors for fiber optics were invented in the course of development of the fiber optic communication industry. Certain of them were extremely popular in the field but have now been used for مندوب الياف بصرية a variety of purposes, but are now becoming obsolete.
The most popular fiber optic connectors that are used today include SC, ST, LC, FC, MTRJ, SMA and a few other less popular ones. You will surely see new connectors invented with the advancement of technology.
