New type of wideband communication optical fiber with low water peak

In this paper, we described a new type of wideband communication fiber with low water peak. The new fiber has excellent dispersion performance. It allows WDM technology to be applied on the range: E band to L+ band, which wavelength range is from 1370nm to 1650nm. It has relative low relative dispersion slope called as RDS, which makes high bit rate transmission system be easy to realize full dispersion compensation with low cost. Low water peak characteristics of new fiber provide necessary condition to extend operation range to E band. New fiber has moderate effective area, which makes new fiber have flexible amplification choices. Excellent PMD performance makes new fiber be suitable for higher bit rate transmission system.
