Optical cable directly buried and optical cable laying in the pipeline are two common ways of optical cable laying, they have some differences in installation methods, protection measures, maintenance costs and application occasions:Optical cable directly buried and optical cable laying in the pipeline are two common ways of optical cable laying, they have some differences in installation methods, protection measures, maintenance costs and application occasions:Optical cable directly buried and optical cable laying in the pipeline are two common ways of optical cable laying, they have some differences in installation methods, protection measures, maintenance costs and application occasions: Installation method:Optical cable direct burial: The optical. Direct burial optical cable installation involves burying the cable directly underground through trenching and grooving. Currently, long-distance trunk optical cable projects and local transmission network optical cable lines in suburban areas mostly utilize direct burial. The construction steps. Recommendation ITU-T L. First, in order to demonstrate sufficient performance of an. Buried optical fiber cable: External optical cable or steel wire armor, directly buried in the ground, requires resistance to external mechanical damage and soil erosion performance. Different protective layer structures are selected according to the use environment and conditions, for example. 1. 2 meters from the ground surface.
