All-Optical Carrier Recovery with Periodic Optical Filtering for Wavelength Reuse in RSOA-based Colorless Optical Network Units in Full-Duplex 10Gbps WDM-PONs
Fiber optics communications Modulation All-optical devices
2015/6/10
Optically assisted downstream cancellation for wavelength reuse in WDM-PONs is demonstrated, allowing downstream extinction ratios up to 9dB for symmetrical full-duplex data transmission at 10Gbps wit...
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.
