Why PoLRE?
Phybridge Power over Long Reach Ethernet (PoLRE) switches go beyond traditional PoE. PoLRE switches are specifically designed to allow businesses to optimize their converged LAN platform. This game-changing switch innovation moves the convergence point from every desktop to a single point in the central closet-greatly reducing costs, risk and complexity while eliminating many of the compromises associated with layering voice on your data switch fabric. With a PoLRE backbone complementing the data switch fabric, you are guaranteed voice quality of service, voice continuity with no data LAN dependencies, and a highly secure topology with the physical separation of voice communications. Best of all, there's no need to replace the IP phone or power source when upgrading your data speeds to the desktop: The separate PoLRE backbone supports your bandwidth and power requirements today and in the future.
