NON-ZERO DISPERSION SHIFTED OPTICAL FIBER WITH DEPRESSED CORE HAVING LARGE EFFECTIVE AREA, LOW SLOPE AND LOW DISPERSION

摘要

An optical waveguide fiber including a centermost core segment surrounded by four other core segments. At a wavelength of about 1550 nm, the optical fiber exhibits an effective area of greater than about 50 mum<2>, a dispersion of greater than about 4 ps/nm/km, and a dispersion slope of less than about 0.03 ps/nm<2>/km.
