This corrosion-resistant waterproof type optical cable for pipeline is through setting up second waterproof layer 500 and second anticorrosive coating 600 at the optical cable skin, as the anticorrosive waterproof first barrier of optical cable to the at utmost prevents the invasion of moisture and the corruption of microorganism, through set up first waterproof layer 200 and second anticorrosive coating 600 at the optical cable inlayer, as the anticorrosive waterproof second barrier of optical cable, with the further corruption that prevents cable core 100. The placement platform 710 is convenient for fixing the optical cable on the cable tray, and prevents the optical cable from moving. The placing positions of the placing platforms 710 are designed through the placing positions of the optical cables, the number of the placing platforms 710 is at least two, and the placing platforms 710 are arranged at intervals so as to ensure that the placing platforms 710 are abutted against the cable supporting plate or the pipe wall. In one embodiment, the number of placement platforms 710 is four, and the four placement platforms 710 are uniformly distributed around the outer sheath 700 centered on the cable core 100.

As shown in fig. 1 to 3, in an embodiment, the cable core 100 is installed in the center of the optical cable, the cable core 100 is sequentially provided with a first waterproof layer 200, a first anti-corrosion layer 300, an armor layer 400, a second waterproof layer 500, a second anti-corrosion layer 600, and an outer sheath 700 outward, and moisture, microorganisms, corrosive gas, and the like in the external environment of the pipeline are primarily blocked by the outer sheath 700. The platform 710 of putting of oversheath 700 is convenient for the placing of optical cable, and a plurality of protruding posts 711 align the distribution in axial and vertically, and a plurality of protruding posts 711 increase the friction dynamics of putting platform 710 and external environment for there is the optical cable of putting platform 710 to compare and be fixed in on pipeline wall or the cable layer board in cylindric easier, thereby avoids the landing of optical cable so that the maintenance of later stage.
