1. Tensile strength
    Traction mode by pipeline laying optic fiber cable, you must consider the tensile strength of the fiber optic cable. When the cable lifting, in the vertical pipe, the suspension in between two poles or laying on the seabed, tensile reinforcement member must be able to support the weight of the cable itself. Hanging overhead fiber optic cable between two telephone poles must also withstand the test of heavy snow and strong winds.
2. Anti-extrusion capacity
    Sometimes cable may be subjected to large impact force from the side, such impact force may be crushed fiber. Some cables must also be resistant to live large transport RCC.
3. Excessive bending protection.
    Sharp bend will bring the two issues that the bend generated radiation loss, and second, the fiber may be damaged. Good cable should have sufficient strength, it is possible to prevent excessive bending; same time, also have a certain flexibility in order to ensure easy transport and laying.
4. Injury protection
    Glass fibers in the case of damage performance sharply deteriorated. Tiny cracks caused by the injury extends along the glass and the loss of a significant increase.
5. Vibration isolation
    The vibrations may cause the increase of the fiber loss. In the design of the cable to the fiber plus pads can limit excessive movement.
6 moisture-proof and anti-chemical attack
    Glass fiber prolonged exposure to moisture and chemicals into the performance deterioration. The appropriate cable structure is able to protect the optical fiber, so as not to contact with these substances. Except that should have high mechanical strength and chemical protective performance, good cable should also have light weight, small size, more flexibility, and fire prevention, animal biting, and not sensitive to temperature and other properties.
