Required Resolution of Digital-Analog-Converter for Optical OFDM
Fiber optics communications Modulation
2015/6/4
The required resolution of digital-analog-converter for optical OFDM was evaluated through simulation and experiment. Signal degradation caused by quantization was independent of subcarrier modulation...
On the Required Number of WDM Channels When Assessing Performance of 100Gb/s Coherent PDM-QPSK Overlaying Legacy Systems
WDM Channels When Assessing Performance Coherent PDM-QPSK Overlaying Legacy Systems
2015/7/15
We experimentally analyze WDM nonlinear impairments brought by co-propagating 10Gb/s NRZ channels onto a 100Gb/s PDM-QPSK channel. The PDM-QPSK channel can experience strong nonlinear interactions eve...
Reduction of the Required Number of Electrical Regenerators by Physical Layer Impairment Aware Regenerator Placement and Routing
Electrical Regenerators Physical Layer Impairment Routing
2015/8/6
The number of OEO regenerators required for a fixed blocking probability in a translucent network can be reduced drastically, if physical layer impairments are considered during regenerator placement ...
