Hybrid 2.5G/10G Co-existing OFDMA-PON Employing Single Receiver at the OLT
Fiber optics communications Systems
2011/5/25
A 2.5G/10G co-existing OFDMA-PON is demonstrated through 20km SSMF with 31dB loss budget. Only one receiver at the OLT and low-speed transceiver at the 2.5G ONUs are required, thereby reducing system ...
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...
An Efficient MAC Protocol for Asynchronous ONUs in OFDMA PONs
MAC Protocol OFDMA PON Asynchronous ONU
2011/5/18
We propose an efficient MAC protocol for OFDMA PONs that eliminates the synchronization requirement of ONUs and also exploits the statistical multiplexing gain among traffic of all ONUs for high perfo...
44-Gb/s/ Upstream OFDMA-PON Transmission with Polarization- Insensitive Source-Free ONUs
Fiber optics communications Modulation
2010/6/9
For the first time, we demonstrate colorless 44-Gb/s/ upstream OFDMA-PON transmission with polarization-insensitive, source-free ONUs. Superior performance is reported over 20 km SSMF plus 1:3...
