A new, simple, and cost efficient method is experimentally demonstrated to generate 6th order Gaussian derivative optically. Proposed technique is based on directly modulated semiconductor laser, optical filtering and chromatic dispersion of fiber transmission line.
Optical UWB pulse generation and wireless propagation through antenna is investigated. Experimental BER results are presented. It is shown due to antenna characteristics monocycle pulse is converted into 3rd-order Gaussian derivative after wireless propagation.
Today, even in access networks, data traffic is enormously increasing, a trend that causes existing passive optical network (PON) infrastructures to become bottlenecks in a tele- and data-communication infrastructure, which is aimed to be both broadband and seamless. Thus, two major objectives are considered for next-generation PONs (NG-PONs), i.e., first, bandwidth increase, and second, reach extension...
In this paper we demonstrate different techniques for 1 Tb/s QPSK-WDM-OFDM-PON optical power budget extension. Our simulation results show that EDFA outperforms SOA and yields more access budget. We present our simulation results for 64 customers with 0.625/40 Gb/s/λ guaranteed/peak bit rate downstream scenario.
