Deployment of 320 Gbits WDM-PON feasible architecture based on power budget analysis

In this paper, we proposed and demonstrated through simulation the power budget of WDM-PON downstream optical link. It is composed of a CW laser array -LD with an external-injection optical source and operated as external-modulating in a downstream-traffic transmitter of -3 dB. The downstream transmissions at 80 Gbps were performed for four channels covering 60 km. The proposed WDM-PON downstream transmission distance can be extended up to 60 km by controlling transmit power of the external-injection optical source of a spectrally-sliced CW-LD and receiver using p-i-n Photodiode. We verified the potential of the transmitter in WDM-PON optical link.
