General Provisions For Laying Optical Cables

1.2 The traction force for laying the optical cable should not exceed 80% of the allowable tension of the optical cable. The instantaneous maximum pulling force shall not exceed 100% of the allowable tension of the optical cable. The main traction should be added to the strength member (core) of the optical cable.
1.3 The pulling end of the optical cable can be prefabricated or made on site. Directly buried or underwater armored optical cable can be used as a net sleeve or a traction end.
1.4 In order to prevent twisting and damage to the optical cable during the pulling process, a swivel should be added between the pulling end and the pulling cable.
1.5 When laying out the optical cable, the optical cable must be released from the top of the cable drum and maintain a loose arc. There should be no twist in the process of laying the optical cable, and it is strictly forbidden to make small circles, surges and other phenomena.
1.6 When mechanical traction is used for laying optical cables, centralized traction, intermediate auxiliary traction or decentralized traction should be selected according to the traction length, terrain conditions, traction tension and other factors.
1.7 The tractor used for mechanical traction shall meet the following requirements:
1) The adjustment range of the traction speed should be 0-20 m/min, and the adjustment method should be stepless speed regulation;
2) The traction tension can be adjusted, and it has automatic stop performance, that is, when the traction force exceeds the specified value, it can automatically issue an alarm and stop the traction.
1.8 The laying of optical cables must be closely organized and directed by a special person. There should be good means of contact during the traction process. Prohibit untrained personnel and work without contact tools.
