Full-Life-Cycle Guide for GYTA Optical Cables: From Installation Specifications to Intelligent Operation and Maintenance

As one of the most widely used outdoor optical cables, GYTA optical cables have become the first choice for various laying methods such as pipelines, overhead and direct burial due to their good moisture resistance and tensile performance. However, in many projects, the performance of GYTA optical cables has not been fully exerted. The core reasons are non-standard installation and inadequate operation and maintenance. Mastering the key points of full-life-cycle management can keep this "invisible blood vessel" healthy.

Details in the installation link determine the service life. Different laying methods have clear specifications: pipeline laying needs to reserve 15% slack to avoid fiber compression; the spacing between overhead hanging wires should not exceed 50 meters to prevent optical cable sagging; direct burial laying must ensure sufficient burial depth and lay warning tapes above. The sealing of the joint box is the key to waterproofing. Special sealant must be used to reach IP68 protection level, and desiccant should be filled to prevent condensed water. In the operation and maintenance stage, focus on three major faults: increased optical attenuation, fiber breakage and water seepage. Locate the break point with OTDR (Optical Time Domain Reflectometer) and timely clean the joint or replace the optical cable section. Now intelligent operation and maintenance has become a trend. Distributed fiber sensing systems and GIS map management can greatly improve the efficiency of fault location. After an operator in a certain province adopted the relevant system, the fault location time was shortened from 4 hours to 20 minutes.

Standardized installation is the foundation, and intelligent operation and maintenance is the guarantee. Only by taking both into account can the application value of GYTA optical cables be maximized.
