Fast switching of a dual laser PM-QPSK transceiver is used to mitigate channel-power excursions in amplified optical transmission under wavelength reconfiguration.
End-to-end, impairment-aware wavelength path provisioning is experimentally realized in a multi-domain network using a transparent software-defined exchange (tSDX) with real-time OSNR monitoring as an SLA guarantee for 100Gbps PM-QPSK DWDM transmission.
