Detailed Description

◎Applications: Long distance outside telephone, CATV, Data, communications. ◎Installations: Installed in duct, self supporting (Figure 8 self supporting or ADSS All dielectric self supporting) and direct burial (with armoring). ◎ Construction: The cable consists of 5 to 36 elements stranded in up to 3 layers around a central strength member and bound in a jacket. The elements are usually fiber containing tubes. However, fillers are also used, when needed to preserve cable geometry. Two to twelve color coded fibers are loosely laid in each tubes filled with water-blocking gel. ◎ Technical Parameters: ☆ Maximum Transmission Distance: 6km (Single Mode); 0.3km (Multimode) ☆ Maximum Pulling Load: 1500-2700 N (Short Term Installation); 900-1500N (Long Term Installation) ☆ Minimum Bending Radius: Short Term Installation: 20 x Overall Diameter Long Term Installation: 10 x Overall Diameter (Non Armored); 20 x Overall Diameter (Armored) ☆ Twist (Torsion Length): 125 x Overall Diameter ☆ Working Temperature: -40℃ ~ +70℃ (PE sheath) ☆ Storage Temperature: -50℃ ~ +70℃ (PE sheath) ◎ Product Highlights: ☆ All the fiber containing tubes are placed in concentric layers around the central member; through the control of the twist length, the fiber cable can achieve better pulling load and operating temperature. ☆ Tube Materials are water resistant and can sustain high tension. Being filled with special water-blocking gel, the tube can provide water protection for the fibers inside the tube. ☆ Central Member, which is usually either made of dielectric FRP, or solid/ stranded steel coated with polyethylene, are placed at the centre of the cables.
