Abstract: It is disclosed a method for activating an ONU in a multi-wavelength PON. Other ONUs may be already active and transmit upstream signals to the OLT on various upstream channels. The new ONU transmits an activation signal superimposed to such upstream signals. Since the ONU may comprise an uncalibrated tunable transmitter, initially the activation signal wavelength might be different from that upon which the ONU shall be activated. The activation signal optical power is lower than the other upstream signals, so as not to impair their reception at the OLT. The OLT operates the ONUs already active on the upstream channel on which the new ONU shall be activated to suspend transmission for one or more time gaps, during which the OLT detects the activation signal. This improves the activation signal detection conditions, thereby allowing to increase its bitrate. An acceptable duration of the activation procedure is then achieved.

Abstract translation: 公开了一种在多波长PON中激活ONU的方法。 其他ONU可能已经是活动的，并且在上行信道上向OLT发送上行信号。 新的ONU将叠加的激活信号发送到这样的上行信号。 由于ONU可能包括未校准的可调谐发射机，所以最初的激活信号波长可能不同于ONU将被激活的波长。 激活信号光功率低于其他上行信号，从而不损害其在OLT处的接收。 OLT操作在新的ONU被激活的上行信道上已经有效的ONU暂停一个或多个时隙的传输，在该时间间隔期间OLT检测到激活信号。 这改善了激活信号检测条件，从而允许增加其比特率。 然后实现激活程序的可接受的持续时间。

The optical receiver executes the steps of making (100) repetitive wavelength sweeps to detect wavelengths carried by the optical fiber, storing (102) wavelengths calibration values associated with the detected wavelengths and controlling (104) a plurality of reception units through Digital to Analog Converters (DAC) and Ring Resonator Drivers (RRD) (DACDs) by assigning the wavelengths calibration values to the reception units, thereby programming each reception unit to subtract one wavelength from the optical fiber.

Abstract: An optical routing scheme in which an optical network having a mesh topology is configured to route optical packets through an optical routing layout superimposable with the mesh topology, but having a star-like topology. Using this routing layout, the optical network can be configured to transport optical packets from respective ingress nodes, through the hub node located at the star center, to respective egress nodes in a manner that enables a data throughput that approaches the theoretical capacity. No special hardware is required for implementing the hub functionality, and any node of the optical network can be configured to serve as the hub node. The latter feature enables relatively straightforward optimization of the optical routing layout and transmission schedule, e.g., by changing the identity of the hub node and adjusting the transmission schedule at the ingress nodes to synchronize packet arrivals to the hub node.
