Abstract

A new type of communication optical fiber with S+C+L-bands was introduced in the paper. This optical fiber is designed for the application of DWDM system on S+C+L-bands. The effective operating bands can be even extended to E-band and L⁺-band. In order to reduce non-linear effect, such as FWM (four-wave mixing) etc., the minimum dispersion coefficient from 1460nm to 1625nm of the optical fiber is greater than 2ps/nm km, and the effective area at 1550nm is around 60μm². Low dispersion slope is helpful to reduce the cost of dispersion compensation for high bit rate DWDM system and maintain a moderate dispersion value over S+C+L-bands. The dispersion slope of this type of fiber was optimized not to be less than or equal to 0.038ps/km nm² (over C-band ), the dispersion coefficient isn’t higher than 11.4 ps/nm km at 1625nm. By the optimization of manufacturing process and precisely designing on index profile, excellent attenuation and PMD performance were obtained. Attenuations at 1550nm and 1625nm are less than 0.24dB/km, PMD co-efficient is less than 0.05 ps/km1/2.
