“Experts have designed a new high-density lightweight anti bird pecking overhead optical cable to address the problem of frequent damage caused by bird activity in bird active areas. The cable adopts a twisted structure with three 48 core high-density sleeves, achieving high core density while effectively reducing the outer diameter and quality of the cable; At the same time, stainless steel tape armor and red color stripes are used to balance the bird proof performance and mechanical performance of the optical cable. The experimental results show that compared to the conventional GYTS-144B1.3 and GYTA53-144B1.3 optical cables, the force required for high-density lightweight bird proof overhead optical cables to be pecked by 5mm increased by 33.6% and 17.5%, respectively. According to the actual application feedback of the anti bird pecking optical cable, the bird pecking accident rate can be reduced by 80%.”
