Microwave tunable dispersion compensator for optical fiber systems

Abstract

A tunable device based on chirped microstrip delay lines is proposed to precompensate at the transmitter; the chromatic dispersion accumulated during optical fiber propagation. Compensated dispersion is finely tuned by changing the effective dielectric constant of the microstrip line by means of moving dielectric perturbers. Compensation up to $51\mathrm{ps}/\mathrm{GHz}$ necessary to propagate over $400\mathrm{km}$ uncompensated standard single-mode fiber at $10\mathrm{Gb}/\mathrm{s}$ is demonstrated. The proposed solution does not require coherent detection and can find application in metropolitan and regional area networks, where the physical path traced by each channel can change owing to the traffic routing, requiring the dynamic compensation of different amounts of accumulated dispersion.
