Problems solved by technology

[0006] With the application requirements of photoelectric hybrid cables, multiple photoelectric units need to be arranged in multiple photoelectric transmission stages, and the butterfly structure is used to make the space more compact. Therefore, most of the photoelectric units with different transmission functions or transmission stages currently use simple Easy-to-tear thin layer jacket, but because most of the optical-electrical hybrid cables need to protect the optical-electrical hybrid cable and need to be easy to tear, so how to achieve both buffer protection and easy to tear is the current priority of the butterfly optical-electrical hybrid cable One of the hottest research
