  • PON (passive optical network) station side apparatus, PON uplink line communication method, and program recording medium
    Patent number: 8238752
    Abstract: A PON station side apparatus is provided with a selection section and a receiving section. For multiple data transferred from multiple PON terminal apparatuses that transmit data at different communication speeds in time division multiplexing, the selection section selects any of the multiple receiving circuits to be a receiving circuit for a receiving destination at which data is received on the basis of the transmission time zones for the data. The receiving section switches the receiving circuit selected by the selection section among the multiple receiving circuits to be the receiving circuit for the destination at which data is received of the data and receives the data through the switched receiving circuit.
