M-PSK Versatile Modulation using a Single-electrode Straight-line Phase Modulator and Digital Signal Processing for ISI-suppression
Coherent communications Fiber optics communications
2010/6/5
BPSK, QPSK, and 8-PSK modulation/demodulation was experimentally demonstrated using only a single-electrode straight-line phase modulator for the first time. ISI caused by the modulation was compensat...
Study on ISI Mitigation Capability of MLSE Equalizers in RSOA-based 10Gbit/s WDM PON
lSI Mitigation Capability MLSE Equalizers RSOA-based WDM PON
2009/7/20
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...
Fast Experimental BER Extraction of 40 Gb/s Optical Signal Impacted by Jitter, ISI and ASE Noise Using Waveform Sampler
Optical Signal Impacted Jitter ISI ASE Waveform Sampler
2008/8/4
We present a new experimental BER extraction method using a sampling oscilloscope and statistical processing on EDFA noise, photoreceiver noise, jitter and ISI successfully tested on a 40 Gb/s network...
Linewidth-Tolerant,ISI-suppressed 15-Gbit/s 64-QAM Transmission over 120-km SSMF
Linewidth-Tolerant ISI-suppressed Transmission SSMF
2008/7/31
2.5-Gsymbol/s 64-QAM transmission over 120-km standard-SMF was demonstrated by electronic pre-equalization for ISI supression and pilot-carrier aided optical phase-noise cancelling to obtain the BER o...
ISI Pre-equalization in a Vector Modulator for 5 Gsymbol/s 64-QAM
ISI Pre-equalization Vector Modulator Gsymbol/s
2008/7/31
We investigated the performance of electronic pre-equalization to compensate for ISI caused in a vector modulator for 5 Gsymbol/s 64QAM. Drastic improvement in the constellation was experimentally con...
