1. Tensile strength
    The tension strength of the cable must be taken into account when piping the cable. When the cable is hoisted, in the vertical pipe, between the two poles or laid on the bottom of the sea, the anti-tension reinforcement must be able to support the weight of the cable itself. The overhead cable that hangs between the two poles must also be tested by heavy snow and winds.
2. Anti-extrusion ability
     Sometimes the cable may suffer from a large impact from the side, this impact may crush the fiber. Some cable must also be able to withstand the large-scale transport of rolling.
3. Excessive bending protection
     Sharp bending will bring two problems, one will produce radiation at the bend loss, and second, the fiber may be damaged. Good cable to have enough strength to prevent excessive bending; the same time, but also have some flexibility to ensure easy to transport and laying.
4. damage protection
     Glass fiber in the case of damage to the performance will be rapidly deteriorated. The fine cracks caused by the damage will extend along the glass and increase the loss significantly.
5. Vibration isolation
     Vibration can lead to an increase in fiber loss. In the design of fiber optic cable, to the fiber with a pad can limit excessive movement.
6. Moisture and chemical resistance
       If the glass fiber is exposed to moisture and chemicals for a long time, the performance will deteriorate. A suitable cable structure protects the fiber from contact with these materials. In addition to high mechanical strength and chemical protection performance, good cable should also have a light weight, small size, more flexible, fire, anti-animal bite and temperature-insensitive and other properties.
