Problems solved by technology
[0004] Especially, under the condition of low temperature, the sheath material of the optical cable has strong shrinkage performance, but the optical fiber will not shrink, which leads to the excessive length of the optical fiber in the optical cable, which is easy to bend and fold in the optical cable, and improves the performance of the optical fiber. The additional attenuation affects the transmission performance of the fiber

The invention discloses a high and low temperature resistant remote optical cable and a manufacturing process thereof. The high and low temperature-resistant remote optical cable comprises a cable core and an inner reinforcing layer, an inner protective layer, an outer reinforcing layer and an outer protective layer which wrap the cable core in sequence, and at least three inner-layer non-metal reinforcing members are embedded in the inner protective layer and are uniformly distributed in the inner protective layer in the circumferential direction. The outer-layer non-metal reinforcements of which the number is the same as that of the inner-layer non-metal reinforcements are embedded in the outer protective layer and are arranged on the extension lines of the cable core and the inner-layernon-metal reinforcements, and the outer surfaces of the inner-layer non-metal reinforcements and the outer-layer non-metal reinforcements are respectively provided with a gluing layer. According to the manufacturing process of the high and low temperature resistant remote optical cable, an optical fiber unit is subjected to optical fiber bundling, an inner sheath process and an outer sheath process to form the high and low temperature resistant remote optical cable. The cable is suitable for the transmission scenes of the indoor and outdoor communication base stations, can be used under highand low temperature conditions, and has the good tensile and side pressure resistance characteristics.
Description
technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a high and low temperature resistant remote optical cable and a manufacturing process thereof. Background technique [0002] With the rapid development of communication technology, the traditional cable communication technology is gradually replaced by optical fiber communication technology due to its own limitations, and the physical channel of transmission is also converted from cable to optical cable accordingly; optical fiber remote is accompanied by radio frequency remote And the optical fiber repeater technology, through the excellent transmission characteristics of the optical fiber, the remote baseband signal and the radio frequency signal are realized, which facilitates the site selection of the base station, the installation of the antenna feeder, and the rational use of carrier frequency resources. It is a technology that has developed rapidly in re...
