In-service dispersion monitoring in 32/spl times/10.7 Gbps WDM transmission system over transatlantic distance using optical frequency-modulation method

Abstract

We develop an in-service dispersion monitoring technique based on the optical frequency modulation (FM) method and examine its applicability to wavelength division multiplexing (WDM) long-haul transmission systems. This method is insensitive to the group-delay drift induced by environmental perturbations and can measure the dispersion value with its sign… (More)
