Double braided double sheath sensing cable is a specially designed optical fiber communication cable with the following advantages:
1. High-strength protection: The double braided double sheath structure gives the cable double protection, which can effectively protect the internal optical fiber from external pressure, stretching, etc., improve the cable’s ability to resist external forces, and reduce the risk of breakage.
2. Corrosion resistance: The double sheath design can effectively prevent the cable from being corroded by corrosive substances such as acids, alkalis, and chemicals, and protect the stability of signal transmission inside the optical fiber.
3. Waterproof performance: Double braided double sheath optical cables usually have good waterproof performance, which can prevent moisture from penetrating into the cable and improve the stability of the cable in a humid environment.
4. High bending performance: The double braided double sheath structure can increase the flexibility and bending performance of the cable, making it suitable for occasions where bending installation is required, reducing the restrictions on laying and installation.
5. Anti-electromagnetic interference: Double braided double sheath optical cables can effectively isolate external electromagnetic interference and improve the stability and accuracy of optical fiber transmission.
6. High security: The double-braided double-sheathed optical cable has a complex structure and strong protection, which helps reduce the occurrence of optical cable failures and breaks and improves the reliability and security of the communication system.
Note: The outer sheath material, color and printing information of the optical cable can be customized according to customer requirements
