Description

As Power over Ethernet (PoE) cables can exist in bundles and pass through walls where natural cooling can be limited, there is a potential for the cables to experience excessive heating resulting in the deformation of the cable and degradation of the transmission performance. This paper reviews previous investigations into the challenges of PoE technology. Studies conducted on possible enhancement strategies are presented. Results show that power and data capabilities of the structured cabling can be enhanced by reducing the cable bundle size and by deploying cables with better construction and larger conductor diameter.
