Problems solved by technology

Optical cables in the prior art usually use composite aluminum strips, corrugated steel strips, etc. to strengthen the mechanical properties of optical cables. The biggest disadvantage of this strengthening method in use is that it is not ideal in terms of lateral pressure resistance and bending flexibility. In the case of repeated torsion, the optical cable is easy to crack, which affects the performance of the optical cable
In addition, in the communication industry standard YD / T769-2010 of the People's Republic of China, optical cables such as GYXTS and GYXTY are also mentioned. , the role of armored protective optical cable, but its anti-lateral pressure, anti-bending softness needs to be improved
