Improvement of Chromatic Dispersion and Differential Group Delay Tolerance of Incoherent Multilevel Signaling with Receiver-side Digital Signal Processing
Fiber optics communications Modulation
2010/6/10
Chromatic dispersion and differential group delay tolerance of 30-Gbit/s 8DPSK and 8QAM signaling is investigated experimentally, and we show 1.7 and 1.25 times enhancement of them in 8QAM signaling b...
Efficient Frequency Domain Chromatic Dispersion Compensation in a Coherent Polmux QPSK-Receiver
Coherent communications Optical Communications
2010/6/10
We investigate frequency domain chromatic dispersion equalization in an ASIC for digital coherent signal processing. Improved chromatic dispersion tolerance can be achieved by using modified coefficie...
