WDM Channels When Assessing Performance Coherent PDM-QPSK Overlaying Legacy Systems
2009/7/15
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...
Single-Carrier vs. Dual-Carrier Transmission of 100Gb/s coherent PDM-QPSK over NZ-DSF Fibre
Single-Carrier Dual-Carrier Transmission coherent PDM-QPSK over NZ-DSF Fibre
2009/7/14
We experimentally compare 100Gb/s PDM-QPSK in single-carrier and dual-carrier configuration over 800km of NZ-DSF fibre. Using 40Gb/s P-DPSK and 10Gb/s OOK neighbours the lower tolerance to nonlinear e...
Experimental Analysis of 100Gb/s Coherent PDM-QPSK Long-Haul Transmission under Constraints of Typical Terrestrial Networks
Coherent PDM-QPSK Long-Haul Transmission Constraints Typical Terrestrial Networks
