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
