First OpenFlow-based Software-Defined -Flow Architecture for Flex-Grid OFDMA Mobile Backhaul over Passive Optical Networks with Filterless Direct Detection ONUs
OpenFlow-based Software-Defined Flex-Grid OFDMA Mobile Backhaul Passive Optical Networks Filterless Direct Detection ONUs
2014/11/6
We demonstrate the first software-defined OpenFlow1.0-based flex-grid -flow architecture enabling 150Mb/s per-cell OFDMA MBH overlays onto bidirectional 10Gb/s PON, without any ONU-side optica...
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 ...

Computationally-Efficient DSP-based MIMO Equalization OSNR gains 40Gb/s OFDMA-PON
2011/5/25
We present and experimentally verify a novel computationally-efficient MIMO equalization method in 40Gb/s OFDMA-PON with polarization multiplexing and direct detection. A 2.1dB DSP-based OSNR gain is ...
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...

64/32/16QAM-OFDM Direct-Detection 40G-OFDMA-PON Downstream
2011/5/20
A 43.6Gb/s downstream OFDMA-PON is demonstrated using optical single-side band 64/32/16QAMOFDM signals and direct-detection receiver through 20km SSMF. Only one photodiode/OFDM receiver is required at...
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...
Dynamic λ-OFDMA with selective multicast overlaid
Dynamic λ-OFDMA selective multicast overlaid
2011/5/18
We experimentally demonstrate a dynamic λ-OFDMA with selective DPSK overlaid,and multicast control is realized through an alternative LO. The 10-Gb/s P2P signal, 2.5-Gb/s overlaid and 1.25-Gb/s upstre...
