Optical ASK-DPSK and QAM Signal Generation Using FWM in High Nonlinearity Fiber (HNLF)
Optical ASK-DPSK QAM Signal Generation FWM High Nonlinearity Fiber (HNLF)
2011/5/20
As a modulation-format transparent nonlinear process, FWM is capable of generating complex optical signal constellations. In experiments and simulations, optical ASK-DPSK and 8-QAM signals are generat...
COST-EFFICIENT WDM QAM TRANSMISSION OF 100 Mbit/s OVER 100m 1mm CORE DIAMETER POLYMER OPTICAL FIBER
COST-EFFICIENT WDM QAM TRANSMISSION POLYMER OPTICAL FIBER
2008/8/3
By transporting the I- and Q-baseband QAM components using two inexpensive 460nm and 520nm wavelength LEDs, 100Mbit/s transmission over 100m large core SI PMMA POF has been realized.
Transmission of 40-Gbit/s 16-QAM Signal over 100-km Standard Single- mode Fiber using Digital Coherent Optical Receiver
Transmission Signal over Standard Single- mode Fiber Digital Coherent Optical Receiver
2008/7/31
We demonstrate 100-km transmission of a 40-Gbit/s 16-QAM signal using a digital coherent receiver. The receiver sensitivity of -30 dBm is obtained at BER=10 -5
50-km SMF transmission of 50-Gb/s 16 QAM generated by quad-parallel MZM
SMF transmission QAM quad-parallel MZM
2008/7/31
We investigated transmission of 50Gb/s 16QAM over 50km SMF. 16QAM was electro-optically synthesized with a quad-parallel MZM; demodulated by off-line digital homodyne employing electric equalizers.
