What is the minimum clear distance between buried optical fiber cable and non buried buried communication cable?

What is the minimum clear distance between buried optical fiber cable and non buried buried communication cable?

Of course, there are other ways of laying cable type 333: under.Air blowing method: air blown micro cable, usually FTTH.The best use of optical fiber and cable standard, we use the finite general wiring engineering.

Direct buried cable: laying directly buried in the ground, generally choose type 53 fiber cable, side pressure requirements are more stringent;Aerial optical cable: self supported overhead and non self supporting aerial, self-supporting type aerial optical cable, such as ADSS cable, OPGW, non self support aerial, such as GYTA, and hanging on the tower when installing;

Different laying methods, YDT/901 suitable cable type, laying way is different, the performance of optical fiber cable is not the same.Pipeline fiber optic cable: laying in the pipeline, the usual types of fiber optic cables are GYFTY, /GTYS/GYTA and so on;
