Abstract
A novel subscriber loop architecture is proposed that uses central optical power feeding as well as polarization/wavelength multiplex bidirectional transmission. Because of the possibility of polarization conversion at the terminal, bidirectional transmission of the power feeding channel can be accomplished in a single fiber subscriber link, and economic fabrication of the entire subscriber terminal as an integrated optical unit is possible.
