TECHNICAL FIELD

[0001] The utility model belongs to the field of optical fiber cable, especially relates to the flame-retardant optical fiber cable. BACKGROUND

[0002] Optical fiber cable is a kind of communication medium for transmitting optical signals, usually composed of multiple optical fibers and protective layer. Optical fiber is a kind of slender transparent fiber, which transmits optical signals by total reflection principle, and has advantages of high bandwidth, low loss and anti-interference. Optical fiber cable is widely used in long-distance communication, data transmission and internet connection fields. The outer layer of optical fiber cable usually has protective materials, such as plastic cover and steel wire, to protect the optical fiber from physical damage.

[0003] According to a kind of high-temperature-resistant flame-retardant optical fiber cable (publication number: CN210572921U) including first sleeve, the inside of the first sleeve is equipped with rubber strip, the front of the rubber strip is equipped with through-hole, the outer wall of the first sleeve is equipped with high-temperature-resistant flame-retardant mechanism, the outside of the high-temperature-resistant flame-retardant mechanism is equipped with second sleeve. The high-temperature-resistant flame-retardant optical fiber cable can effectively isolate the optical fiber inside, prevent the optical fiber from being damaged due to high temperature and open flame, and the cooperation between steel wire mesh and steel wire greatly improves the tensile resistance and cutting resistance of the high-temperature-resistant flame-retardant optical fiber cable, the service life is greatly improved compared with traditional optical fiber cable, ensuring normal transmission of information. The reinforcing rib not only improves the strength of the second sleeve, but also allows the operator to quickly determine whether the high-temperature-resistant flame-retardant optical fiber cable is twisted.
