Transmission of 96×100Gb/s with 23% Super-FEC Overhead over 11,680km, using Optical Spectral Engineering
Transmission Super-FEC Overhead Optical Spectral Engineering
2015/5/20
We transmit 96 PDM-QPSK channels at 100Gb/s over 11,680km, matching the best capacity × distance product reported, but with C-band-only EDFAs. 2.7b/s/Hz spectral density is obtained, despite 23% super...
Significant Overhead Reduction of Multi-band Tb/s Coherent Optical OFDM Systems
Multi-band Tb/s Coherent Optical OFDM Systems Overhead Reduction
2015/5/15
The timing and optical laser phase of individual bands in multi-band OFDM are correlated. We significantly reduce the OFDM overhead through using FFT window synchronization for channel estimation and ...
Fully DC-Coupled 10Gb/s Burst-Mode PON Prototypes and Upstream Experiments with 58ns Overhead
Fully DC-Coupled Burst-Mode PON Prototypes Upstream Experiments Overhead
2015/6/11
This paper presents a chain of four fully DC-coupled 10Gb/s burst-mode prototypes operating with 58ns overhead for the first time. 10Gb/s upstream burst-mode experiments are performed without a time-c...
Reducing Cyclic Prefix Overhead in Optical OFDM Systems
Reducing Cyclic Prefix Overhead Optical OFDM Systems
2015/7/14
Simulations show that by pre-compensating for dispersion, using bands transmitted with timing offsets and a single-band receiver, the cyclic prefix to be reduced in optical OFDM systems without compro...
