Abstract :
In this paper, we investigate the required range of ONU transmit power levelling for TWDM-PONs based on the worst case inter-channel crosstalk analysis. To overcome the crosstalk impairment, an OLT-shared architecture of the ONU transmit power levelling and its operation rule is also proposed.
