Investigation of Spectral Efficient Modulation Formats for 400Gbit/s/port Optical Packet Switched System
Switching Packet Optical communications
2015/6/8
We investigate the performance of NRZ-OOK, NRZ-DPSK, NRZ-DQPSK, NRZ-8PSK and NRZ-16-QAM modulation and their influence to an optical packet switched systems (OPS) performance.The aim was to demonstrat...
Spectral-efficient OOFDM system using compatible SSB modulation with a simple dual-electrode MZM
Frequency modulation Fiber optics optical communications
2015/6/8
A direct-detection OOFDM transmission is experimentally demonstrated which does not need a guard-band between the carrier and the OFDM sideband. The compatible-SSB modulation is realized through a sin...
Demonstration of High Spectral Efficient OFDM-QAM Long Reach Passive Optical Network
High Spectral Efficient OFDM-QAM Passive Optical Network
2015/8/4
We demonstrate a high spectral-efficient LR-PON using 4Gb/s OFDM-QAM for both up-and-downstream, achieving a high split-ratio 256, using optical components optimized for GPON.
