Central Loose Tube Fiber Optic Cables
 |
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 a single tube containing 2 up to 24 fibers, which is filled with water-blocking gel. When the cable contains more than 12 fibers, they are divided in two groups. A colored thread identifies each group. Physical protection and tensile strength are provided by aramid yarn or fiberglass wound around the tube. Either PE or LSZH jacket can be used. A ripcord is located under the jacket to facilitate jacket removal.
Technical Parameters
☆ Maximum Transmission Distance: 6km (Single Mode); 0.3km (Multimode)
☆ Maximum Pulling Load: 1500N (Short Term Installation); 900N (Long Term Installation)
☆ Maximum Compressive load: 3000N (3.3mm loose tube diameter); 5000N (4.5mm loose tube diameter)
☆ Twist (Torsion Length): 125 x Overall Diameter
☆ Working Temperature: -20℃ ~ +70℃ (PE sheath)
☆ Storage Temperature: -40℃ ~ +70℃ (PE sheath)
Product Highlights
☆ Small diameter and light weight.
☆ Through the control of the fiber exceed length which is the key technology in optical fiber manufacture, 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.
☆ Compact construction of the fiber cores can prevent the fiber to shrink back. This can sustain higher tensile stress
and achieve better flexibility.
☆ Wide operating temperature range.
