A directional coupler is an unequal power divider; a splitter is an equal power divider. Both have the abbreviation TFC (trunk/feeder coupler) in their model names because they split your network’s trunk and feederlines.
A line power inserter passively combines radio frequency (RF) signals with up to 90 volts alternating current (VAC) from a line power supply. This device enables a single cable to service the power and signal requirements of active modules in a broadband telecommunications network.
