Experimental demonstration of penalty-free optical cross-connectcascade with multiwavelength transmission over 1000-km standard fiber

摘要

An optical cross-connect (OXC) architecture was proposed toimplement high-capacity transparent wavelength-division multiplexing(WDM) optical transport networks. A laboratory demonstrator was built toassess the feasibility of this concept. We report here a penalty-freecascade experiment of three 4×4, eight-channel OXCs operated at2.5 Gbit/s including WDM transmission over 1000-km nondispersion-shiftedfiber
