[0002] Communication optical cable is a communication line composed of several optical fibers, a cable core covered with a sheath, and reinforcement elements and sheaths arranged outside the cable core. It uses one or more optical fibers placed in the sheath as a transmission medium and can be used for communication lines that transmit various signals within a certain length. Communication optical cables may be subjected to pressure from various aspects during laying and use. The compressive structure of the optical cable can improve the mechanical properties of the optical cable, making it not easily damaged when subjected to external pressure, thereby ensuring the normal operation and transmission performance of the optical cable.
[0003] In the existing anti-compression structure of the communication optical cable, the outside of the communication optical cable is not filled, resulting in poor anti-compression effect of the communication optical cable. The communication optical cable is easily damaged during use. Therefore, it is necessary to propose a anti-compression structure for the communication optical cable project. Utility Model Content

[0013] 1. A compression-resistant structure of a communication optical cable project, through the arrangement of an optical fiber, a protective cover and a compression-resistant frame, during the use of the device, the compression-resistant frame is filled outside the protective cover so that the compression-resistant frame fills the gap of the communication optical cable core, maintains the shape and stability of the communication optical cable, and prevents the optical fiber from bending or deforming due to temperature changes. The compression-resistant frame can protect the optical fiber, enhance the compressive strength of the communication optical cable and the ability to withstand external force loads, and ensure that the communication optical cable is not easily damaged during use;
[0014] 2. The compression-resistant structure of a communication optical cable project is provided with an inner sheath and a water-blocking layer. During the use of the device, the water-blocking layer is provided on the outer side of the inner sheath. Since moisture may penetrate into the interior through the sheath of the communication optical cable and cause damage to the communication optical cable, the water-blocking layer can prevent or slow down the intrusion of moisture, protect the components inside the communication optical cable from being damaged by moisture, and improve the waterproof performance and stability of the communication optical cable;
[0015] 3. The compression-resistant structure of a communication optical cable project is provided with an insulating layer and an anti-corrosion layer. During the use of the device, the anti-corrosion layer is provided on the outside of the insulating layer. Since the communication optical cable may be laid in a harsh environment, such as soil, water, and atmosphere, these environmental factors may cause corrosion and damage to the communication optical cable. The anti-corrosion layer can protect the optical cable from corrosion and damage by environmental factors, thereby extending the service life of the communication optical cable.
