Unrepeatered Transmission over 300 km of NZDSF Using 8x112-Gb/s Time-Interleaved RZ-PDM-QPSK with Coherent Detection and Forward Raman Pumping
Unrepeatered Transmission Coherent Detection RZ-PDM-QPSK
2015/5/15
We show that time-interleaved RZ-PDM-QPSK and forward Raman pumping can increase the performance of a 112-Gb/s PDM-QPSK coherent unrepeatered transmission system over 300 km of NZDSF by more than 2 dB...
40 km long-range Raman-based distributed temperature sensor with meter-scale spatial resolution
Fiber optics sensors Scattering Raman
2015/6/10
We propose a new Raman based distributed measurement technique which allows for temperature sensing over nearly 40 km of graded index multimode optical fiber with meter-scale spatial resolution and te...
Stability of Amplified DPSK WDM Transmission against Raman Crosstalk Effects
Pulse propagation temporal solitons Raman effect
2015/6/5
We investigate Raman-crosstalk-induced amplitude dynamics in amplified DPSK WDM transmission. We prove existence and stability of equilibrium states with nonzero amplitudes in all channels. Our result...
Polarization Insensitive All-Optical Retiming Based on Cross-Phase Modulation and Offset Filtering with Distributed Raman Amplification
Polarization Insensitive All-Optical Retiming Based Cross-Phase Modulation Offset Filtering Distributed Raman Amplification
2015/7/31
Adding distributed Raman amplification to a polarization insensitive all-optical retiming technique based on cross-phase modulation and offset filtering reduces the timing jitter of 10 Gb/s retimed si...
