    Abstract

    We have experimentally demonstrated a real-time 25 Gbps transmission for C-Band up to 40 km SSMF without optical or digital chromatic dispersion compensation by using a single sideband quasicoherent receiver with sensitivity of -20 dBm (pre FEC BER = ${5\cdot 10^{5}}$) and 40 km dispersion penalty below 6.3 dB.
