Transmission of 96×100Gb/s with 23% Super-FEC Overhead over 11,680km, using Optical Spectral Engineering
Transmission Super-FEC Overhead Optical Spectral Engineering
2011/5/20
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...
Progress in Soft-Decision FEC
Soft-Decision FEC
2011/5/18
We discuss the practical implementation of LDPC codes in soft-decision FEC for 100 Gb/s digital coherent systems. The question of the definition of net coding gain for differential QPSK used to avoid ...
RSOA-based 10G WDM PON using FEC and MLSE Equalizers
Fiber optics links subsystems Semiconductor optical amplifiers
2010/6/10
Achieving the 10Gbit/s transmission in RSOA-based WDM PON systems is one of the important challenges because of its strict modulation bandwidth. This paper describes various state-of-the-art technique...
A Triple-Concatenated FEC using Soft-Decision Decoding for 100 Gb/s Optical Transmission
