◆ Advantages
Able to be set up with power transmission lines on the same tower
Normally it's not necessary to stop power supply for construction
It saves a large sum of construction costs
Made from non-metallic material
Resistant to strong electromagnetic field
Excellent mechanical properties and environmental flexibility
◆ Center loose tube type
Able to be used for span less than 300 meters;
A small diameter, light weight, small specific payload, small additional load upon the tower;
Disadvantage is limited number of cores as it's below 24 cores, limited surplus length of optical cable, poor tensile properties.
◆ Loose tube layer strand
Surplus length of optical cable can be easily controlled, span can be more than 1000 meters, greater number of cores, 2~144 Universal structure
