MLSE-Based Nonlinearity Mitigation for WDM 112 Gbit/s PDM-QPSK Transmissions with Digital Coherent Receiver
Coherent communications Fiber optics communications
2015/5/26
We investigate the performance of linear equalization combined with MLSE in long-haul transmission. In the nonlinear regime with high launch powers Q-factor improvement up to 1.4 dB is demonstrated wi...
Performance Comparison of MLSE-Based Receivers in a 1000 km Transmission Link under Fast SOP Variations
Fiber optics links subsystems Polarization
2015/6/10
This paper aims at comparing the tolerance to fast SOP variations of two MLSE-based receivers. Descriptions of the emulation device and measurement method are given. The results show that the receiver...

Fiber optics links subsystems Semiconductor optical amplifiers
2015/6/10
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...
Colorless 10Gb/s extended reach WDM PON with low BW RSOA using MLSE
Optical Communications Fiber optics amplifiers oscillators
2015/6/10
A low bandwidth RSOA-based WDM-PON system is evaluated at 10Gb/s with an off-line processing. Results show that almost 20Km bidirectional and 125km unidirectional fiber are feasible by means of 8 stat...
Coherent CD Equalization for 111Gbps DP-QPSK with One Sample per Symbol Based on Anti-Aliasing Filtering and MLSE
Fiber optics communications Coherent communications
2015/6/9
W e propose a coherent detection scheme with one sample per symbol. MLSE is used to compensate for ISI introduced by anti aliasing filtering. 50,000 ps/nm of CD is fully compensated with only 1 dB pen...

lSI Mitigation Capability MLSE Equalizers RSOA-based WDM PON
2015/7/20
Detailed performance analysis of MLSE receivers in RSOA-based 10Gbit/s WDM PON systems is presented. We found the impact of ISI from preceding bits could be larger than succeeding bits and 8-state MLS...
