RBGPOE is completely different from RBPOE. It has two complete L/C filters in order to allow power and data into 4,5 and 7,8 couples of cat. 5e cable.
RBPOE instead uses only 1,2 and 3,6 couples for data, and 4,5 - 7,8 couples for power, and so it only allows 100 base TX connection.
Other differences are:
RBPOE has ground connection only from F and M RJ45 ports, instead RBGPOE has also the ground connection with power plug, and that is a major issue, because often we connect ground with the power supplies and we need to solder a ground cable to use RBPOE in this way.
Those poe adapters are useful in centralized power supply in base stations, but they are very uncomfortable in single subscriber installations, so we buy ubiquiti active poe injector for subscribers and cannot use the standard power supply provided by Mikrotik.
I hope that in the future Mikrotik would provide a compact poe unit with ground connection, similar to ubiquiti ones.
