Abstract: One embodiment of the present invention provides a system that reduces data burst overhead in an Ethernet passive optical network which includes a central node and at least one remote node, wherein downstream data from the central node is broadcast to the remote nodes, and wherein upstream data from a remote node is transmitted to the central node in a unicast manner. During operation, the central node transmits grant messages to a number of remote nodes, wherein a grant message for a specified remote node assigns a start time and a duration of a transmission timeslot in which the specified remote node may transmit an upstream data burst. In response to the grant messages, the central node then receives a number of upstream data bursts, wherein the time gap between two consecutive upstream data bursts is less than the summation of a default laser turn-on time, a default laser turn-off time, an AGC period, and a CDR period.

Abstract: An optical fibre network comprises a hub, an optical router, and a plurality of optical network units (ONUs). In the downstream direction from the hub to the ONUs, the optical router receives channels having predefined wavelength ranges from a uni-directional input fibre and divides the channels so bi-directional input/output fibres receive at least one of the plurality of channels. In the upstream direction from the ONUs to the hub, the optical router receives the channels from the bi-directional input/output fibres, combines them, and outputs them to a uni-directional output fibre. For any particular channel, in the downstream direction it is routed to a first bi-directional input/output fibre and in the upstream it is routed from a second bi-directional input/output fibre different from the first bi-directional input/output fibre.

Abstract: A control circuit refers to a time schedule of a time slot assigned to each of slave stations, which is stored in a first storage, and an optical intensity of each of signal packets sent from the slave stations, which is stored in a second storage, and preliminarily knows when and from what slave station an upstream signal packet is received and the optical intensity of the upstream signal packet to be received. When the control circuit determines the optimum bias voltage of an APD, in an interval between signal packets, a bias control circuit provides a bias source with a timing signal, by which an output voltage of the bias source is changed, and a bias voltage setting signal. The bias source applies a bias voltage corresponding to the bias setting signal sent to the APD with the optimum timing synchronized with the timing signal.
