Example Embodiment
[0036] New optical fiber laying example one:
[0037] Such as figure 1 As shown, this embodiment proposes a method for laying a new optical fiber, which is suitable for optical cable processing, and includes the following steps:
[0038] 1) Connect the tee 4 at the inlet of the laying target pipeline 2, connect one of the inlets of the tee 4 to the liquid drive and recovery system 1, the other inlet to the optical fiber supply system 3, and the outlet to connect to the laying target pipeline 2.
[0039] 2) First turn on the liquid driving and recovery system 1, pump the liquid working fluid into the laying target pipeline 2, then turn on the optical fiber supply system 3 to slowly feed the new optical fiber into the tee 4, and use the drag force of the liquid working fluid to The new optical fiber is brought into the laying target pipeline 2.
[0040] 3) When the new optical fiber reaches the length to be laid, the liquid driving and recovery system 1 and the optical fiber supply syst...
Example Embodiment
[0041] New optical fiber laying example two:
[0042] Such as figure 2 As shown, this embodiment proposes another method for laying a new optical fiber. This method is suitable for laying downhole optical fiber without considering fiber replacement, and includes the following steps:
[0043] 1) In the oil well, there is an auxiliary pipeline 5 and the laying target pipeline 2 to form a U-shaped structure, and a U-shaped joint 6 (such as the bottom end of the well for oil fields) is set at the U-shaped ends of the two pipelines. image 3 Shown) to construct a liquid communication channel between the two pipelines.
[0044] 2) Connect the tee 4 at the entrance of the laying target pipeline 2, connect one of the inlets of the tee 4 to the liquid drive and recovery system 1, the other inlet connects to the optical fiber supply system 3, and the outlet connects to the laying target pipeline 2; connect the auxiliary pipeline The outlet is connected to the liquid drive and recovery system ...
