What 's the difference betweeen an ordinary ONU and POE ONU ?

Functionally, it is poor whether it supports POE. Technically, equipment hardware and software are different.
POE is a reverse power supply, which requires a different design of the user interface circuit, and the cost is also higher. The POE device does not need an external power supply, and the PC can supply power to the ONU in the reverse direction through the network cable.

Industrial Grade ONU is also known as PD ONU, POE ONU, Reverse POE ONU, etc. that can satisfy Client-power Supply through POE Power.

Product Overview:

E8008U-PD series are based on client-power supply switch designed for the carrier-class access ONU. All series can provide client-power supply, two-story wire-speed forwarding capability, strong security features, low-power quiet fan-less design and a strong awareness capacity function, which can realize passive access network programs from OLT to passive optical splitter. The series targeted at the business applications of enterprise and carrier networks which is hard to get power. It also serves as energy-saving access and high security access solutions.
