Summary

n Baud rate alone does not scale with future data growth requirements.

n To meet current bandwidth demands we need advanced modulation schemes for both coherent and PAM4.

n For coherent systems, DSP, linear MZ drivers and TIAs enable software configurable data rates for long haul, metro and DCI markets.

n Inphi’s PAM4 platform solutions doubles the data rate compared to NRZ for network scaling.
