摘要： A transceiver unit for use at an end-location in a communications network includes a downstream monitor configured to monitor downstream optical signals that travel from a service provider to the end-location. The downstream optical signals carry downstream data for use by a device in communication with the transceiver unit. At least a portion of the optical path traveled by the downstream optical signals is on a common optical fiber that carries downstream optical signals for other end locations. The transceiver unit also includes an upstream attenuator configured to attenuate upstream optical signals traveling from the end-location to the service provider. At least a portion of the optical path traveled by the upstream optical signals is on the common optical fiber. The transceiver unit also includes electronics configured to operate the upstream optical attenuator in response to output from the downstream monitor.
