Comparison of OFDMA and SC-FDMA Channel Access Techniques in a Passive Optical Network Environment
Comparison OFDMA SC-FDMA Channel Access Techniques Passive Optical Network Environment
2011/5/25
For the first time, OFDMA and SC-FDMA are compared experimentally as candidate uplink access techniques for next-generation PONs. Important issues like peak-to-average power ratio, optical beat interf...
Comparison of Two CS-SSB Modulators Used in Bidirectional Carrier Distributed Long-Reach Passive Optical Network
Two CS-SSB Modulators Carrier Distributed Reach Passive Optical Network
2011/5/18
Two different CS-SSB modulators based on Mach-Zehnder structure used in carrier-distributed long-reach passive optical networks are investigated and compared. The Rayleigh-backscattering beat noise to...
360km Field Transmission of 10 Gbit/s Stream Cipher by Quantum Noise for Optical Network
Fiber optics communication Optical security encryption
2010/6/10
Secure optical transmission experiment is demonstrated using a stream cipher by quantum noise. The bit error rates of a 10Gbit/s signal through 360km fiber for authentic receiver and eavesdropper are ...
Optical Network Planning with Rate-Tunable NRZ Transponders
Optical Network Planning Rate-Tunable NRZ Transponders
2009/7/16
We present simple reach estimators for 5 to 15Gb/s NRZ channels in commonly deployed networks and assess the benefits of tunable data-rate in core optical networks through routing and resource allocat...
