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...
