Transmission of 112 Gb/s PM-QPSK Signals over 7200 km of Optical Fiber with Very Large Effective Area and Ultra- Low Loss in 100 km Spans with EDFAs Only
Transmission 112 Gb/s PM-QPSK Signals Optical Fiber Ultra- Low Loss EDFAs Only
2015/5/20
We experimentally investigate transmission of 16×112 Gb/s PM-QPSK signals over an optical fiber with effective area of 134 μm 2 and attenuation of 0.162 dB/km. We demonstrate transmission over 7200 km...
Dynamic Model of Spectral Hole Burning for EDFAs with 980-nm-Pumping
Dynamic Model Spectral Hole Burning EDFA 980-nm-Pumping
2015/5/20
Spectral hole burning (SHB) in the gain spectrum of EDFAs influences the dynamic response of EDFAs and their electronic control. A 3-level-model incorporating SHB has been derived and numerically inve...

We study transmission of 40 Gb/s signals using coherent RZ-QPSK with and without polarization multiplexing using 100km large effective area fiber-spans and dual-stage EDFAs with mid-stage dispersion c...
Investigating the Limits of Optical Packet Transmission Through Cascaded Transient-Suppressed EDFAs Without Regeneration or Active Gain Control
Erbium Fibers Packet-Switched Networks
2015/6/8
Using a transmission loop, we show the maximum number of cascaded conventional-EDFAs is gain-transient limited for packet transmission and demonstrate error-free, noise limited packet transmission acr...
