2014/11/6
We demonstrate wavelength- and mode-division multiplexed transmission over a fiber re-circulating loop comprising 50-km of low-DMGD few-mode fiber, and an optimized few-mode EDFA with a flat gain spec...
117-Gb/s Optical OFDM Super-channel Transmission over 1200-km SSMF Using Direct Detection and EDFA-Only Amplification
Fiber optics communications Modulation
2015/5/22
With EDFA-only amplification, we successfully demonstrate the transmission of a 4-QAM, 117-Gb/s (100 Gb/s without overhead) DDO-OFDM super-channel over 1200-km SSMF with only 1-dB OSNR penalty. We als...
Less than 0.19-dB Transient Gain Excursion AGC-EDFA with Digital Control for 20-Channel Add/Drop Equivalent Operation
Transient Gain Excursion AGC-EDFA Digital Control 20-Channel Add/Drop
2015/5/20
We have developed a digitally controlled AGC-EDFA by combining an FF-controlled pump-LD and an FB-controlled VOA. An FPGA is used to finely tune the gain setting of the pump current with a wide dynami...
