In this paper, an algorithm for the estimation of the linear inter-channel crosstalk in a dense-WDM polarization-multiplexed 16-QAM transmission scenario is proposed and demonstrated. The algorithm is based on the use of a feed-forward neural network

We experimentally investigate the impact of laser frequency linewidth and jitter on the design of uplink point-to-multipoint 800G DSCM systems. The performance degradation due to sub-band overlap, bandwidth limitation and DSP penalty is quantified.

Passive optical network (PON) based on coherent detection has attracted a great deal of attention in recent years as a future solution for 100+ Gbps per wavelength. Particularly for 200G-PON, one of the most attractive options would be to switch to Q

The demand for high speed in wireless communication is a big concern since the number of connections is increasing. The employment of higher carrier is strongly recommended and millimeter wave (mm-wave) frequency are necessary in the future. In this

Due to the growth of the number of communication devices over the last decades, the millimeter wave (mm-wave) band has been strong interest. In fact, this band offers a massive bandwidth and highest speed. However, in order to obtain the highest rece

A new approach for designing broad and flattened spectrum multicarriers optical sources is presented leading to a 32 spectral lines source by using a dual-arm Mach–Zehnder modulator (MZM) and a 41 spectral lines source from two-stage MZM. A modifie
