Many poorly designed switches exist in the market, and the majority of them are fragile, fail easily, and often suffer from transmission delay or unreliable communication conditions due to packet collisions or other issues. In contrast, ICP DAS switches are built using truly industrial-grade switch chips that are temperature tolerant and highly reliable. These switches are all well designed by skilled engineers, and are subjected to very strict communication and environment tests prior to shipment. All ICP DAS switches have a long operational lifetime and function perfectly under harsh environmental conditions.
