Single Pair Ethernet (SPE) technology revolutionizes building connectivity by reducing traditional four- pair Ethernet requirements to just two wires while providing integrated Power over Data Line (PoDL) capability. SPE connector options include IP20 PCB jacks and IP67 sealed circular versions designed for 4A current capacity, supporting current applications while providing upgrade paths for future IoT devices without vendor lock-in constraints. Time-Sensitive Networking (TSN) applications demand deterministic networking with guaranteed latency characteristics for real-time control applications where traditional best-effort delivery isn't sufficient for safety-critical systems. Amphenol's early SPE investment and selection as the Zhaga Book 20 standard connector demonstrates technology leadership rather than standards compliance, helping create the standards that define future building automation. Building network infrastructure transforms individual systems into intelligent, interconnected ecosystems where today's connectivity decisions determine whether buildings can support tomorrow's technologies. C h a p t e r 4 | R o b u s t C o n n e c t i v i t y f o r S m a r t N e t w o r k s Single Pair Ethernet isn't just about reducing cable count—it's about fundamentally simplifying building infrastructure while enabling IoT device densities that four- pair systems can't support. Our early SPE investment means customers can deploy next-generation architectures today rather than waiting for industry maturation. Being first to market with mature technology creates competitive advantages that compound over time."
