Figure 8 Armored Fiber Optic Cable
Description
Ingo provides figure 8 armored fiber optic cables with a central tube bundle sheathed into a Y or S shape. This fiber operatic cable is most often used in self-supporting aerial laying. The structure combines with fiber optics with a diameter of 250μm inside the loose tube made of highly modulus materials. The loose tube is filled with a waterproof compound, and at the center of the cable core is a metallic strengthening core. The loose tube strands and the central strength member form a compact and round cable core. After being longitudinally wrapped by a layer of APL, the cable core is integrated into a figure 8 PVC jacket with steel wires.

| application: self-supporting aerial laying | |||||
- The steel wires have an extremely high tensile strength that is convenient for self-supporting aerial laying.
- The figure 8 armored fiber optic cable has a great mechanical behavior and temperature characteristics.
- The loose tube materials feature a great hydrolysis resistance and relatively high strength.
- A special grease fills the loose tube in order to offer critical protection for the fiber optic.
Use the following measures to ensure the waterproof performance of the optical cables
- Using the single steel wire as central strength member.
- Filling up the loose tube with special waterproof compound.
- 100% cable core filling
- Using APL as moisture barrier.
