Chromatic dispersion compensation in coherent transmission system using digital filters.
We present a comparative analysis of three popular digital filters for chromatic dispersion compensation: a time-domain least mean square adaptive filter, a time-domain fiber dispersion finite impulse response filter, and a frequency-domain blind look-up filter. The filters are applied to equalize the chromatic dispersion in a 112-Gbit/s non-return-to-zero polarization division multiplexed quad...
متن کاملExperimental demonstration of adaptive digital monitoring and compensation of chromatic dispersion for coherent DP-QPSK receiver.
We experimentally demonstrate a digital signal processing (DSP)-based optical performance monitoring (OPM) algorithm for in-service monitoring of chromatic dispersion (CD) in coherent transport networks. Dispersion accumulated in 40 Gbit/s QPSK signal after 80 km of fiber transmission is successfully monitored and automatically compensated without prior knowledge of fiber dispersion coefficient...
متن کاملEnergy-Efficient Chromatic Dispersion Compensation for Coherent Fiber-Optic Receivers
DSP-based chromatic dispersion compensation accounts for a large part of the overall power dissipation in fiber-optic receiver ASICs. We have implemented and evaluated compensation filters based different design methods using a MATLAB-based coherent fiber-optic system model in respect to compensation performance, filter length, and fixed-point aspects. Possible power savings when taking into ac...
متن کاملChromatic Dispersion Mitigation in Single Carrier High Speed Coherent Optical Communication Using Digital Signal Processing Techniques
Optical fiber networks have been emerged to be the backbone of global communication infrastructure in present world. But, they are currently experiencing an unprecedented level of stress in order to meet the demand of increasing bandwidth-hungry applications. Moreover signals are frequently subjected to distortion due to optical fiber impairments while being propagating through a fiber optic ca...
متن کاملChromatic Dispersion Compensation using Optical All Pass Filters
The purpose of this paper is to experimentally study Optical All Pass Filters (OAPF) and optimize the value of distance of origin from poles (r). Using the value of transfer function of optical all pass filter which is of 2 order we found the factor of numerator and denominator. In this work, we took the value of ̳r‘ as 0.660 and the angular position (w0) as 0.390. The power taken as 18dBm. Whe...
