Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a fireproof optical cable. Background Art

[0002] Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups;

[0003] The insulation layer of the optical cables currently on the market is generally made of polyvinyl chloride, which is a flammable organic compound. The existing optical cables using polyvinyl chloride as the insulation layer have low fire resistance, which makes the optical cables not have excellent fire resistance. Once they encounter flames or electric sparks, they are easily ignited, causing burns and damage to the optical cables. The protection effect on bundled optical cables is poor. For this reason, we propose a fire-resistant optical cable. Utility Model Content

[0011] Preferably, the material of the high temperature resistant filling layer is high temperature resistant grease, and the material of the wear-resistant layer is polycarbonate. By providing the wear-resistant layer, the wear resistance of the optical cable during use is improved, and the service life of the optical cable is increased.

[0012] The utility model provides a fireproof optical cable. The fireproof optical cable has the following beneficial effects:

[0013] (1) The fireproof optical cable adopts a multi-layer fireproof design by providing a flame-retardant filling layer, a fireproof layer and a high-temperature resistant filling layer. The flame-retardant material and the fireproof layer work together to prevent the spread of flames in a fire environment and maintain basic signal transmission performance. In addition, by providing a waterproof layer, the infiltration of water and moisture into the optical cable during use can be reduced, thereby extending the service life of the optical cable.
