摘要:
A transmission system for a passive optical network comprises a shared optical transmission apparatus, a shared electrical interface apparatus and a plurality of transmission convergence termination units. The shared optical transmission apparatus is configured for being coupled to an optical line termination unit via an optical fiber. The shared electrical interface apparatus is coupled to the shared optical transmission apparatus. The plurality of transmission convergence termination units is coupled to the shared electrical interface apparatus. Each one of the transmission convergence termination units is configured for selectively controlling the shared electrical interface apparatus.

摘要:
An amplifier circuit in a PON and a method for using the same. The amplifier circuit may be used, for example in an ONU of the PON. In order to deal with varying customer requirements and the possibility of the ONUs or similar devices being installed at varying distances from the CO, a dynamically adjustable amplifier bias voltage is determined and applied to at least one amplifier in the amplifier circuit. The dynamic bias voltage is preferably a function of the input power to the ONU or the circuit output quality, or both. More than one dynamic bias voltage may be determined and applied in this fashion.
