Today, Fiber Closure manufacturers share the benefits of fiber optic communications.

With the increasing speed of information technology transmission, fiber optic technology has received extensive attention and application. In multi-microcomputer elevator systems, the application of optical fiber fully meets the requirements of a large number of correct, reliable, high-speed transmission and processing of data communication. The application of fiber optic technology in the elevator greatly improves the reaction speed of the entire control system, and the parallel group control performance of the elevator system has been significantly improved. The fiber optic communication device used on the elevator is mainly composed of a light source, a photoreceiver and an optical fiber.

Optical fiber communication has many advantages: it has wide transmission bandwidth and large communication capacity; low transmission loss and long relay distance; fine wire diameter and light weight; raw material is quartz, saving metal materials, which is conducive to rational use of resources; insulation and electromagnetic interference resistance It has strong anti-corrosion ability, strong anti-radiation ability, good wrapability, no electric spark, small leakage, strong confidentiality, etc. It can be used in special environment or military.

The principle of optical fiber communication is: at the transmitting end, the transmitted information (such as voice) is first converted into an electrical signal, and then modulated onto the laser beam emitted by the laser, so that the intensity of the light changes with the amplitude (frequency) of the electrical signal. And transmitted through the optical fiber; at the receiving end, the detector receives the optical signal and converts it into an electrical signal, and after demodulation, restores the original information.
