Currently, the application of optical fiber communication is spread in the fields of submarine communication, long-distance trunk, cable television, local area network, and the like.
Optical fiber cables are the most common materials in the field of information communication, and their weather resistance or erosion resistance often determines the stability of optical fiber information transmission systems. However, as the industrial development expands to the harsh environment of deep sea, plateau and the like, the existing optical cable often cannot meet the industrial requirements. For example, under severe tropical marine environmental conditions, the structure and performance of the optical cable can be seriously affected by damp heat, high temperature, vibration and even severe environments full of salt mist and oil mist all year around, and the optical cable is easy to age and break, so that the optical fiber is exposed, the stability of information transmission is damaged, and huge economic loss is caused; solar radiation, temperature and humidity have the greatest effect on the aging of the cable, which causes the rubber material of the outer surface to become stiff and brittle by losing its elasticity. Thus, it can be seen that weatherability has become one of the important performance criteria for optical cables. In terms of the general weather resistance, the rubber has the properties of ultraviolet resistance, heat resistance, cold resistance, water erosion resistance, sand erosion resistance and wind erosion resistance, and has the properties of ozone resistance and the like.
