LARGE KAPPA DISPERSION COMPENSATING FIBER AND TRANSMISSION SYSTEM

摘要

A dispersion compensation fiber (20) for a moderate dispersion, low slope transmission fiber (19) and transmission system (18) including same. The dispersion compensating (20) fiber has a refractive index profile having a central core (22) with a core delta (?1), a moat (24) surrounding the central core (22) having a moat delta (?2), and a ring (26) surrounding the moat (24) having a positive ring delta (?3). The fiber's refractive index profile is selected to provide total dispersion less than -80 at 1550 nm and less than -90 ps/nm/km at 1600 nm, dispersion slope less than -0.18 ps/nm
