For optical cables containing metal components, lightning current must be directed to the ground by installing lightning protection wires (drainage wires).
In the underlying fabric of modern information society, data flows at high speeds between buildings, factories, data centers, and communication hubs, like blood.
When multiple cores of an integrated cable are connected in parallel, crosstalk between signals is one of the key factors affecting system stability and performance.
iber optic cable production is typically carried out at high speed and continuously, requiring the testing system to be seamlessly integrated with the production line to achieve real-time testing and feedback.
Security cables, however, can continuously supply power for tens of minutes to several hours in open flames exceeding 950°C, ensuring the normal operation of critical equipment such as fire pumps, emergency lighting, alarm systems, and elevator controls.
This distortion accumulates over long distances, becoming a key factor limiting the performance of fiber optic communication systems.
