Selective level measurement, ONT simulation and subsequent performance evaluation

XGS-PON will elevate the entire telecommunications infrastructure to a new speed level, at least wherever optical fiber is installed. The target: 10 gigabit/s. What makes the technology special is that it can use the same fiber infrastructure that has already been installed for GPON over wide areas. But this also entails new measuring challenges. This is because XGSPON uses different optical wavelengths from GPON, which not only permits the same fibers to be used, but also the concurrent deployment of GPON and XGS-PON on one and the same optical fiber line.
