Abstract: Optical network units (ONUs) for high bandwidth connectivity, and related components and methods are disclosed. A fiber optical network ends at an ONU, which may communicate with a subscriber unit wirelessly at an extremely high frequency avoiding the need to bury cable on the property of the subscriber. In one embodiment, an optical network unit (ONU) is provided. The ONU comprises a fiber interface configured to communicate with a fiber network. The ONU further comprises an optical/electrical converter configured to receive optical downlink signals at a first frequency from the fiber network through the fiber interface and convert the optical downlink signals to electrical downlink signals. The ONU further comprises electrical circuitry configured to frequency convert electrical downlink signals to extremely high frequency (EHF) downlink signals at an EHF, and a wireless transceiver configured to transmit the EHF downlink signals to a proximate subscriber unit through an antenna.
