It is not a simple project to lay optical fiber cable. It is necessary to prepare for the optical fiber cable laying project and the normal work in the future. Optical fiber cable manufacturers will let you know about the inspection work.
Before laying the optical fiber cable, the construction unit should check the optical fiber cable to ensure its smooth and well-drained. The anti-corrosion layer of the metal part should be complete, and the lighting and ventilation in the tunnel should meet the relevant requirements. For the optical fiber cable inspection, the main reason is that its model, voltage and specifications meet the design requirements, and the staff can not switch to other types of optical fiber cable. Moreover, the appearance of the optical fiber cable cannot be damaged, and the insulation is good.
If there is any doubt about the sealing of the optical fiber cable, the optical fiber cable manufacturer recommends that the humidity be judged, and the optical fiber cable and the optical fiber cable should be tested to ensure that they are qualified. The oil pressure of the oil-filled optical fiber cable should not be lower than 0.15MPa. The oil supply valve is in the open position to ensure flexible operation; the pressure gauge indicates no abnormality, all the pipe joints should have no leakage oil problem, and the oil sample also meets the test and reaches the qualified level. .
The optical fiber cable take-up frame used in the construction should be placed securely, and the strength and length of the steel shaft should also match the weight and width of the optical fiber cable. Before laying, the length of each optical fiber cable should be calculated according to the design and actual path. The optical fiber cable should be arranged reasonably to minimize the optical fiber cable joint. When installing an optical fiber cable in a live area, there should be reliable safety measures.
