115 Gbit/s downstream and 10 Gbit/s upstream TWDM-PON together with 11.25 Gbit/s wireless signal utilizing OFDM-QAM modulation

Abstract

In this work, we propose and investigate a 115 Gbit/s (4 x 28.75 Gbit/s) downstream and 10 Gbit/s upstream time- and wavelength-division-multiplexing passive optical network (TWDM-PON) together with 11.25 Gbit/s wireless broadcasting signal using multi-band orthogonal-frequency-divisionmultiplexing (OFDM) modulation within 10 GHz bandwidth. Here, to compensate the power fading and chromatic dispersion in the higher frequency, we utilize a -0.7 chirp parameter Mach-Zehnder modulator (MZM) for the OFDM signal. Hence, negative power penalties of -0.3 and -0.4 dB in the downstream and broadcasting wireless signals; and power penalty of 0.3 dB in the upstream signal are measured at the bit error rate (BER) of 3.8 x 10 (3) after 20 km standard single mode fiber transmission without dispersion compensation.
