Applications: Long distance telephone, catv, data communications. Installations: Installed in duct, self supporting (figure 8 self supporting or adss all dielectric self supporting) and direct Burial (with armouring). 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: -20íµ ~ +70íµ (pe sheath) Storage temperature: -40íµ ~ +70íµ (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. íewide operating temperature range.

í= Applications: Short and medium distance, indoor and protected environments. Offered as a riser, plenum, or general purpose cable, it is used for interconnection of distribution boxes, or the distribution boxes and customer equipments, and between floors. í= Installations: Installed along the wall, the roof, interlayer, canal and indoor. í= Construction: The cable contains 4 to 72 fibers individually buffered to 0.9 mm in a tight or semi tight construction and coded. The cable structure depends on the number of fibers: The 4 to 12 fiber cables contain individual fibers without sub-units,In the 16 to 72 fiber cables the fibers are grouped in the sub-units. In the 4 to 12 fiber cables, the individual fibers are stranded and protected by aramid yarn and a PVC or LSZH jacket. In the 16 to 72 fiber cables, the fibers are grouped into sub-units which are laid helically along the cable axis. Each sub-unit contains 4 to 6 fibers, aramid yarn and a PVC or LSZH jacket. The 72 fiber cable consists of twelve sub-units, nine of them are stranded around a central element made of 3 sub-units. í=Technical Parameters: íe Maximum Transmission Distance: 6km (Single Mode); 0.3km (Multimode) íe Maximum Pulling Load: 100N(Short Term Installation);60N(Long Term Installation) íe Minimum Bending Radius: Short Term Installation: 20 x Overall Diameter Long Term Installation: 10 x Overall Diameter (Non-Armoured); 20 x Overall Diameter (Armoured) íe Twist (Torsion Length): 125 x Overall Diameter. íe Working Temperature: -10íµ ~ +70íµ (PE sheath) íe Storage Temperature: -20íµ ~ +70íµ (PE sheath) í= Product Highlights: íe Small diameter and light weight. íe The high tension characteristics of the aramid yarn serving as strength member can offer good stability in the transmission performance. íe Compact and flexible construction are especially suitable for indoor installations. íe Tight Buffer fibers are made from fiber rods with good linearity and low extruding output. By careful calibration of the vacuum pumping equipment, the uniformity of the outer diameter of the tight buffer fibers can be easily achieved with excellent strip ability. íe LSZH jackets can be offered for indoor application for which flame retardancy is required. íe Cutting edge production equipment, good quality materials and optimized process ensure low induced attenuation within the operating temperature range. íe Fiber geometry are strictly monitored to ensure superior transmission performance. roll,box,drum
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: -40íµ ~ +70íµ (pe sheath) Storage temperature: -50íµ ~ +70íµ (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. Roll, box, drum
