Construction matters of branch optical cables
Construction matters of branch optical cables mainly include planning and design, construction preparation, laying of optical cables, protection measures, testing and acceptance, etc.
First, detailed planning is required before construction, including the route selection of optical cables, optical cable types, length calculation, repeater or distributor location setting, etc. During the construction preparation stage, the required optical cables, joint boxes, terminal boxes, protective tubes, warning tapes, signboards and other materials and tools should be prepared12.
When laying optical cables, a layer of fine sand should be laid at the bottom of the ditch, and then the optical cables should be laid flat on the sand to avoid direct contact between the optical cables and the bottom of the ditch to prevent moisture erosion. After laying, a protective tube should be covered on top or backfill soil should be used for protection, and the backfill soil should be compacted in layers to avoid uneven force on the optical cables due to loose soil1.
In terms of protection measures, obvious marking stakes should be set along the optical cables, including information such as the direction and depth of the optical cables, to facilitate future maintenance and repair. After the construction is completed, strict testing is required, including the transmission performance, splicing loss, attenuation and other parameters of the optical cable to ensure that the design and use requirements are met. 1.
Finally, the entire construction process should be recorded in detail, including construction logs, test data, change records, etc., for future query and management. In actual operation, relevant industry standards and specifications must be followed to ensure construction quality and safety.
