Splitter / Combiner
The splitter / combiner function can be configured using a manual switch located on the front panel (see §4
for details).
The position of the switch shall be selected according to the number of connected BPL ports.

The signal power transmitted to/from each coupler is attenuated by 3dB.
Note
: Position 1 is equivalent to putting BPL 1 & 2 in parallel while Position 2 provides a smarter signal
transmission balance.
Using simultaneously BPL 1 & 2 can result in higher impedance mismatch between the modem and the
coupling systems.
When impedances shown by coupling systems at BPL 1 & 2 are unbalanced, the signal transmission is also
unbalanced.
