REVERSE DISPERSION OPTICAL FIBER AND OPTICAL TRANSMISSION LINE USING REVERSE DISPERSION OPTICAL FIBER

摘要

A reverse dispersion optical fiber having a smallwaveform distortion caused by non-linearity wherein aneffective core area is made at least 50 µm2 and adispersion at a wavelength of the 1.55 µm band is madenot more than -10 ps/nm/km and a dispersion managementoptical transmission line having a small waveformdistortion obtained by connecting a positive dispersionoptical fiber and that reverse dispersion optical fiberin that order along a direction of signal transmissionand having a total dispersion of substantially zero.
