Experimental demonstration of 125Gbit/s half-cycle 32QAM Nyquist-SCM transmission system for short reach communications

A 125Gbit/s single polarization half-cycle 32QAM Nyquist-SCM signal transmission over 2km was experimentally demonstrated using EML and direct detection with a receiver sensitivity of −5.2dBm at BER=3.8×10 −3 over 2km of SSMF for short reach communications.
