WebDWDM QSFP28 PAM4. PAM4 uses Pulse Amplitude Modulation for various distances and band rates on DWDM networks. It applies the QSFP28 format for direct detection optics, not coherent optics and is the result of a multi-source agreement. These DWDM transceivers are available at up to 100G data rates. The reach is extendable up to 80km. WebTable 1: 50G PAM4 DWDM system VS 100G PAM4 DWDM system VS 100G DWDM coherent system. Critical Technologies of 100G Coherent DP-QPSK Scheme 1) Polarization Multiplexing Quadrature Phase Shift Keying (PM-QPSK) QPSK is a multivariate (quaternary) digital frequency band modulation method.
