Two after all data are accurate to the decimal except total climbing number of times and the number of times of nibbling in table 1, just:
the S-1 tested cable is the optical cable with the structure (double-layer polyester fiber layer 5) provided by the invention;
s-2 tested cables are the structural optical cables of the invention, and filling ropes 303 are adopted to replace polyester fibers;
s-3, arranging an armor layer 1 on the tested cable by adopting a tight-sleeve matching adhesive fixing mode on the basis of S-2;
s-4 is a blank control group of PVC cables;
and the four tested cables from S-1 to S-4 all have the same outer diameter (1.8cm), the outer surfaces of the tested cables coated by the same dye are black, PP fiber wires with the wire diameter of 1.5mm are used as core cables 3, all the tested cables have bright yellow trisection marks, the climbing times are calculated by climbing at least 1.0m, less than 1.0m is 0, more than or equal to 1.0m is 1, the average climbing time is calculated by the time length of the whole climbing process, the incomplete climbing process is not included to reduce errors, the average parking time is calculated by keeping the time length of 1S and more at a certain position on the optical cable, and is not calculated to keep the time length of less than 1S.
