40 Power over Ethernet, or PoE, is an increasingly popular
way to deliver both power and data over existing Ethernet
cable, thus freeing applications from the constraint of
AC-power proximity. As the number PoE solutions has
grown so has the applicationsвЂ™ appetite for power.
A new proprietary standard, LTPoE++в„ў, satisfies this hunger
by extending the PoE and PoE+ specifications to 90W of PD
delivered power. LTPoE++ also dramatically reduces engineering
complexity in power sourcing equipment (PSEs) and powered
devices (PDs) when compared to other power-expansion solutions.
Plug-and-play simplicity and safe, robust …
