Introduction: The Data Lifeline of Smart Cities Smart cities use data to manage everything. They control traffic lights with sensors. They monitor public safety with cameras. They even manage water and electricity with smart grids. This data must move through network cables every second. But many people forget a big danger. Fire can destroy these

 Introduction: The Need for Speed in the Digital Age Data centers and smart factories need very high speeds. They often require 10 Gbps or even 40 Gbps. Standard insulation cannot handle these high frequencies well. The signal becomes weak over long distances. At DLAY, we focus on high-speed cable technology. We use physical foaming to

1. Introduction: The Hidden Nervous System of Smart Buildings Modern smart buildings are very complex. They use many sensors and IoT devices to manage lights, heat, and security. All these devices need a “nervous system” to work. This system consists of miles of data cables. Many people only care about data speed. But they forget
