Power-Efficient Time-Domain Dispersion Compensation Using Optimized FIR Filter Implementation
We investigate fixed-point aspects and time-domain ASIC implementations of CD compensation. An optimized implementation gives significant power dissipation reduction for short links, with further reduction if pulse shaping is considered. OCIS codes: (060.1660) Coherent communications; (060.4510) Optical communications
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 کاملDispersion Compensation Filter Design Optimized for Robustness and Power Efficiency
We present an optimized CD compensation filter with improved performance and increased resilience to quantization errors. The filter is given in closed form based on a constrained least-squares problem. OCIS codes: (060.1660) Coherent communications; (060.4510) Optical communications
متن کاملChromatic Dispersion Compensation Using Filter Bank Based Complex-Valued All-Pass Filter
Abstract—A long-haul transmission of 100 Gb/s without optical chromatic-dispersion (CD) compensation provides a range of benefits regarding cost effectiveness, power budget, and nonlinearity tolerance. The channel memory is largely dominated by CD in this case with an intersymbol-interference spread of more than 100 symbol durations. In this paper, we propose CD equalization technique based on ...
متن کاملImplementation and Evaluation of two 512-Tap Complex FIR Filter Architectures for Compensation of Chromatic Dispersion in Optical Networks
Filtering is an important part of digital processing, since the applications often require a change of features of a digital or analog signal. A digital filter is a device or a system that removes or alters certain parts of a signal. Optical fibers are used to transmit information over longer distances and at higher bandwidths than traditional copper cables. In order to enable high-rate transmi...
