AI Technical Summary
When existing figure-eight optical cables are installed over long distances, their weight increases the burden on overhead installations, and they also have insufficient tensile strength.
Glass fiber and reinforcing core are used as the reinforcement mechanism, combined with reinforcing ribs and buffer limit seats to improve structural strength and reduce weight. At the same time, electromagnetic shielding and protection are provided by coated tape and aramid yarn to protect the optical fiber.
This approach achieves improved tensile strength and electromagnetic shielding of optical cables while reducing weight, simplifies long-distance installation, and reduces installation difficulty.
