Zero Wait Transmission: OTN&PID enable “WDM everywhere”
80G/120G
PID = Photonic Integrated Device
Tx/Rx Laser and
Mux/Demux in one
device
Savings:
■80% room space saving
■40% power saving
■70% fiber operation saving With PID
PID to achieve digitalized WDM:
■ No optical amplifier
■ No DCM
■ No wavelength planning
“IP+WDM” architecture is the base of E2E Ultra Broadband
