Principles and Application Scenarios
Product Overview
The RTN PI-DC B10 receives one channel of DC power signals and one channel of GE service signals.
The signal coupling module couples DC power signals and GE service signals into P&E signals and outputs the P&E signals
to the P&E port.
The frequencies of DC power signals and GE service signals do not interfere with each other. Therefore, the two types of
signals can be transmitted over the same twisted pair.

≤ 100 m
•The PI only couples GE signals and power signals, but does not regenerate or strengthen GE signals. Therefore, the
network cable between the UNI-side device and the powered device must not be longer than 100 m.
•The maximum distance between the PI and the powered device varies depending on the power of the powered device.
For details, see technical specifications.
