1. The cablesaerial opticsThey are mainly used for secondary trunk lines and underground optical cable lines, and are suitable for areas with flat terrain and small fluctuations.
2. There are mainly two suspension methods for aerial optical cables: hanging under the steel wire and self-supporting. At present, the steel wire support type is basically used. The laying method is to hang or bundle (roll) the erection through a road suspension line of poles. Aerial optical cables are easily threatened by natural disasters such as typhoons, ice, floods, etc. Aerial optical cables are also easily affected by external forces and the weakening of their own mechanical strength. Therefore, the failure rate of aerial optical cables is higher than that ofoptical fibre wiresdirectly buried and pipe type.
