Optical communication parts

In addition to optical fiber transmission, optical fiber communication must also have optical communication equipment, and the key core of optical communication equipment is optical module; the key of optical module is electric chip and optical active device.

The optical module is a conversion device for photoelectric signals and needs to be plugged into the equipment for use. Both electrical and optical signals are magnetic wave signals. The transmission range of electrical signals is limited, while optical signals can be transmitted faster and farther. However, some current devices recognize electrical signals, so there are photoelectric conversion modules. , The optical module is used to convert the electrical signal into an optical signal at the transmitting end. After transmitting through the optical fiber, the receiving end converts the optical signal into an electrical signal.

The optical fiber communication system is a communication system that uses light as the carrier wave, uses extremely thin glass to draw extremely thin optical fibers as the transmission medium, and uses light to transmit information through photoelectric conversion.

The different components that make up a fiber cable are the core, cladding, ferrule, and connector. After assembly, the fiber core is polished and then it is ready to transmit data. The core is a continuous strand of super thin glass that is roughly the same size as a human hair.

Light travels down a fiber optic cable by bouncing off the walls of the cable repeatedly. Each light particle (photon) bounces down the pipe with continued internal mirror-like reflection. The light beam travels down the core of the cable. The core is the middle of the cable and the glass structure. The cladding is another layer of glass wrapped around the core. Cladding is there to keep the light signals inside the core.
