Technical Field

The invention relates to the technical field of optical cables, in particular to an outdoor remote optical cable.

Background

The optical cable used outdoors needs enough tensile force and has the capabilities of resisting the exposure of burning sun and weathering, resisting cold and high temperature. The conventional outdoor optical cable, as shown in fig. 2, includes an outer jacket 1, an indoor optical cable unit 2, and a filling cord 3. The structure of the steel wire rope is formed by intertwisting a plurality of sub-cables, the outer diameter is large, the steel wire rope is not easy to bend, the reserved length is not easy to determine when the steel tower is installed, the operation is difficult after the steel wire rope is installed on the steel tower, the length of the steel wire rope is wasted, and a lot of inconvenience is brought to the engineering. Meanwhile, due to the stranded structure, the data transmission is not stable when the optical cable is circulated at-40 degrees to 85 degrees.
