Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to an optical fiber-intensive indoor optical cable. Background Art

[0002] At present, fiber-intensive indoor optical cable is a kind of optical cable laid inside buildings, mainly used to connect communication equipment, computers, switches and end-user equipment, etc., to achieve fast and stable transmission of information. Compared with traditional indoor optical cables, fiber-intensive indoor optical cable has a higher fiber core density, which enables it to transmit more signals and data in the same optical cable, meeting the application requirements of high-density and high-bandwidth.

[0003] A fiber-intensive indoor optical cable is disclosed in the Chinese utility model patent application disclosure CN 210803806 U. The device is isolated from the second communication component by a support through an electrical unit, thereby reducing the influence of the heat generated by the electrical unit when working on the transmission performance of the second communication unit. The utility model has multiple first cavities and second cavities, and the Y-shaped support frame is thinner, so that the effective cross-sectional area of ​​the first cavity and the second cavity in the optical cable is relatively large, and more first communication components and second communication components can be placed, and the fiber core density is greater. However, the device has fewer internal protection devices and lacks certain high-temperature protection, which may cause the internal communication mechanism to be affected by the external environment and reduce the quality of internal information transmission. In addition, there is no certain filler protective layer, which greatly reduces the toughness and strength of the device and affects its service life. Utility Model Content
