Anti-aging air holes suitable for optical cables are specially designed ventilation openings made from weather-resistant, anti-aging materials that allow controlled air circulation within optical cable ducts or closures. Their primary function is to balance internal and external pressure, effectively preventing moisture condensation, water ingress, and heat buildup that could degrade fiber performance. By maintaining a dry and stable environment, they significantly extend the service life of optical cables, reduce signal loss, and minimize maintenance needs, making them an essential protective component in outdoor telecommunication, FTTH, and long-haul fiber optic networks.
