Description

Technical Field

[0001] The utility model relates to the field of wire splitting devices, in particular to a wire splitting device for an optical fiber transmission device. Background Technique

[0002] An optical fiber is a medium that uses light waves to transmit information. It consists of a core and a cladding. The refractive index of the core is higher than that of the cladding, and the principle of total internal reflection of light is used to transmit optical signals. Optical fibers are divided into single-mode optical fibers and multi-mode optical fibers according to different transmission modes, and are divided into step-type and graded-index optical fibers according to the refractive index distribution form. The working principle of an optical fiber is to modulate an electrical signal onto a light wave at the sending end, then transmit it through the optical fiber to the receiving end, and demodulate the optical signal back into an electrical signal at the receiving end to complete the transmission of information. Optical fibers are widely used in the field of communication. It can provide extremely high bandwidth and long-distance transmission capabilities, and at the same time has the advantages of low loss, anti-electromagnetic interference, and high security. Optical fiber communication technology is the cornerstone of modern communication networks and is widely used in Internet backbones, data center interconnections, broadcast television transmissions, and various high-speed data communication scenarios.

[0003] The wire splitting device in an optical fiber transmission device is a key component for managing and distributing optical fiber signals. They are usually used to distribute the signals from the main optical fiber to multiple sub-lines for connection to different devices or network nodes. The design and function of the wire splitting device are crucial for ensuring the efficient operation of the optical fiber network. The wire splitting device in the wire splitting transmission device can split different numbers of optical fibers according to different needs. During the wire splitting process, due to the different lengths and positions of the optical fibers, the too-long optical fibers are reserved in the wire splitting box. However, once the number of optical fibers is too large and an optical fiber is damaged, it is difficult to quickly find the specific optical fiber. Therefore, there will be a problem of long maintenance time and affecting work efficiency. Content of the Utility Model
