Maxim’s quad PSE controller support both high power PoE+ and standard PoE applications.

Current PoE (IEEE 802.3.af) standard support up to ~12W (15W in theory) which is good for lower power IP cam, IP Phone and wireless AP, however many power hungry device such as high speed optical PTZ IP camera, IP cam + out door housing and Video IP phone would restricted by the current PoE power limitation. It is good to see the introduction of quad PSE controller that could support up to 45W per port based on PoE+ standrd (IEEE 802.3.at) and is backward compatible with the standard PoE. Hope to see some PoE+ ready IP surveillacen equipment soon.

The IEEE 802.3at (PoE+) wouldn’t be finalised till 2008, though it might just be in time to power the mass deployment of WiMAX point, as many predicted 2008 is the year for WiMAX.
