Power over Ethernet (PoE), where cabling to electronic devices also carries operating power, is expected to develop rapidly in coming years. PoE offers advantages including reduced cabling costs, design flexibility, compactness, scalable design with plug-and-play devices and improved remote service possibilities.
Levels of electrical output from PoE cables are increasing to supply devices including communications, security cameras, lighting, control equipment and others. PoE however poses safety issues including electrical shock and fire risks, which will require modifications to cable safety codes, expected to address fire ignition propensity, flame spread, fuel load and combustion emissions.
