Abstract

The present disclosure relates to a fiber optic network configuration having an optical network terminal located at a subscriber location. The fiber optic network configuration also includes a drop terminal located outside the subscriber location and a wireless transceiver located outside the subscriber location. The fiber optic network further includes a cabling arrangement including a first signal line that extends from the drop terminal to the optical network terminal, a second signal line that extends from the optical network terminal to the wireless transceiver, and a power line that extends from the optical network terminal to the wireless transceiver.
