1. Optical cable line engineering – optical cable and equipment inspection
1.1 Before starting the construction, the construction unit shall carry out a quantitative count and visual inspection of the specifications and programs of the optical cables and equipment transported to the construction site. If any abnormality is found, a key inspection shall be made. Optical characteristics and electrical characteristics should also be tested for optical cables, connectors (live joints), etc.
1.2 The optical cable equipment used in the project must have a product quality inspection certificate, and the items and indicators listed in the product test record submitted by the manufacturer should be checked to see whether they meet the national or ministerial standards and design requirements, or the provisions of the order contract.
1.3 Do not use optical cables and equipment that do not meet the requirements. It can only be used after the general defect repair is qualified.
1.4 The optical cables and equipment that have been inspected shall be recorded.
1.5 General rules for testing optical and electrical properties of optical cables and connectors. fibconet.com

2. Optical cable single-reel inspection
2.1 Check that the specification, program and manufacturing length of the single-reel optical cable shall comply with the provisions of the order contract or design requirements.
2.2 The visual inspection of the optical cable should firstly check whether the cable reel package is damaged, and then open the disk to check whether the optical cable sheath is damaged or not, and whether the optical cable end package is in good condition. If the packaging is seriously damaged or the outer skin of the optical cable is damaged, a detailed record should be made. In the optical cable, it should be checked whether the filler is full, and the physical properties of the filler under high and low temperature should meet the requirements of national standards.
2.3 Filled optical cable should check whether the filling is full, and the physical properties of the filling at high and low temperature should meet the requirements of national standards.
2.4 When the optical cable is inspected at the beginning, the end of the outer end of the optical cable should be checked, and a conspicuous note should be made on the reel. The identification method of the optical cable end should meet the following requirements: facing the Belgian section of the light, the optical fiber with the leading color is arranged clockwise as the A end, otherwise it is the B end (see the product manual for the leading color specification); copper wire group end identification Consistent with the identification regulations for the end of the optical cable.
2.5 Check the quality certificate and test records of the optical cable from the factory, and review the geometry, optical and transmission characteristics, and mechanical and physical properties of the optical fiber, which should meet the contract or design requirements.
2.6 On-site inspection of the optical cable should test the attenuation constant of the optical fiber and the length of the optical fiber.
2.7 Regulations on the electrical properties of copper wires used for business communication and remote supply in optical cables. The insulation resistance of the optical fiber sheath to ground should meet the factory standard.
2.8 After the inspection of the single-reel optical cable is completed, the sealed packaging of the optical cable end and the packaging of the optical cable reel shall be restored. fibconet.com
