Abstract
Digital electronic equalization is a key enabler for the cost-effective deployment of 10 Gb/s optical transmission in metro and regional core networks. The wider dispersion tolerance enabled by digital equalization eliminates the need for Dispersion Compensation Modules (DCMs) and amplifier gain-stages, with correspondingly simpler installation, lower capital cost, and reduced operating footprint and power costs. Digital equalization counters both propagation and component distortion, and so permits the relaxation of component specifications. The use of digital-equalization-enabled Adaptive Distortion Tolerant Transponders on 10G DWDM line cards results in significant system-wide cost savings.
