Fig8 Optic Cable
Product performance characteristics
● Low optical fiber transmission loss and low dispersion.
● Reasonable design and precise control of the excess length of the optical fiber in the loose tube and the cabling method make the optical cable have excellent mechanical and environmental performance.
● The optical cable has a compact structure and adopts an SZ layer twisting structure to ensure that the optical fiber is not subjected to stress in harsh environments.
● The outside of the reinforcement and the inside of the cable core are filled with water-blocking cable paste to ensure the moisture-proof and water-blocking effect of the optical cable.
● The steel belt longitudinally wraps the cable core to make the optical cable more moisture-proof and bullet-proof.
● The steel strands are used as self-supporting parts to meet extremely high tensile strength.

Figure 8 Cable Structure：
Figure 8 optical cable is a central tube filled, steel-polyethylene bonded sheathed, 8-shaped self-supporting outdoor optical cable for communication.
Features：
● Full-section water-blocking structure, ensuring good water-blocking performance.
● Special grease is filled in the loose tube to provide critical protection for the optical fiber.
● The 8-shaped self-supporting structure has high tensile strength, is easy to lay overhead, and has low installation cost.
● Steel-plastic composite belt armor increases the tensile strength and lateral compression strength of the optical cable.
● Polyethylene sheath makes the optical cable have good UV resistance.
● Product service life of more than 30 years.
