Scattered Pilot Channel Tracking Method for PDM-CO- OFDM Transmissions Using Polar-Based Intra-Symbol Frequency-Domain Average
Fiber optics communications Modulation
2015/5/25
We have demonstrated an efficient scattered pilot channel tracking approach with a new polar-based intra-symbol frequency domain average (ISFA) for 16-QAM, 40-Gb/s PDM-CO-OFDM systems. This proposal c...
A Self Wavelength Tracking Method for a Cost Effective WDM-PON with Tunable Lasers
Optical communications Networks
2015/6/10
We demonstrate a self wavelength tracking method for tunable lasers in a WDM-PON.By measuring the back-scattered power by a feeder fiber, we identified and tracked the allocated wavelength of the tuna...
Realtime 40 krad/s Polarization Tracking with 6 dB PDL in Digital Synchronous Polarization-Multiplexed QPSK Receiver
PDL Digital Synchronous Polarization-Multiplexed QPSK Receiver
2015/8/3
Fast polarization changes of 40 krad/s (and 6 dB PDL) are tracked in a 2.8 Gb/s realtime coherent QPSK receiver with 0.7 dB (2.4 dB) sensitivity degradation.
