Abstract:
A single mode optical waveguide comprising:a first fiber component having positive dispersion and a positive dispersion slope in an operating wavelength window between about 1520 nm to 1625 nm; a second fiber component comprising at least three segments including: a first segment having a positive &Dgr;1 %; a second segment having a negative &Dgr;2 %; and a third segment having a positive &Dgr;3 %; wherein &Dgr;1 %>&Dgr;3 %>&Dgr;2 %; wherein the second fiber component has negative dispersion and a negative dispersion slope in an operating wavelength window between about 1520 nm to 1625 nm; wherein the waveguide exhibits an attenuation of no greater than 0.25 dB/km; and wherein the waveguide exhibits an induced bend loss no greater than about 0.05 dB for 100 turns about a 75 mm mandrel.
