Patent ID: 6856736

Claim:
An optical-waveguide cable for transmitting optical signals according to wavelength division multiplex technology, said cable comprising of at least one first section (a), which has fibers of a first type (H), and at least one second section (b), which has fibers of a second type (N), wherein the dispersion of the fibers of the second type (N) is between about 0 ps/(nm·km) and about 12 ps/(nm·km) in a transmission band of from about 1525 nm to about 1625 nm, the fibers of the first type (H) being connected to the fibers of the second type (N) at least one transition point (U) between the first and second sections (a,b), and the fibers of the first type (H) being designated in such a way that they have a larger mode field diameter and a higher dispersion than the fibers of the second type (N).
