        abstract = {Dual polarization in coherent multilevel modulations is capacity enhancing technique and is
center of choice of the researchers for IsOWS communication. In proposed work, a high capacity
i.e. 16 × 100 Gbps system is demonstrated over 16000 km IsOWS link using DSS dual
polarization Quadrature phase shifting keying (DP-QPSK) modulation. For the suppression of
sidebands in the DP-QPSK carrier spectrum, a null biased Mach-Zehndar modulator (MZM) is
considered with input radio frequency (RF) in millimetre range (3 GHz- 300 GHz). Further, a
comparison of QPSK, DP-QPSK, DP-QPSK with orthogonal frequency division multiplexed
modulation (OFDM), and proposed DSS-DP-QPSK is performed to find out optimal technique
for IsOWS systems. Investigation is conducted for evaluation of systems in terms of following
parameters such as error vector magnitude percentage (EVMP), received power, and log BER.
Results revealed that QPSK, DP-QPSK and DP-QPSK-CO-OFDM covered distance 13200 km,
14500 km, and 15600 km respectively but proposed system surpassed their performance and
covered 16000 km successfully.},
