In summary, LTPoE++ is the Linear Technology PoE classification using proprietary signaling methods to provide LTPoE++ powered devices with up to 90W of power. It is interoperable and backward compatible with IEEE 802.3af and 802.3at PoE standards, therefore LTPoE++, PoE+ and PoE devices can be mixed and matched. The LTPoE++ PSE and PD controllers have unique features and benefits that will help users design complete, robust, and cost-effective, high power PoE systems.
