OFS Highly-Non-Linear Fiber combines a high non-linear coefficient with numerical small group velocity dispersion. The fiber design includes a high delta core, surrounded by a deeply depressed ring and doped with Fluorine. The HNLF is available in four versions: a version with a slope of 0.019 ps/(nm²•km), a zero dispersion slope version, a PM version, and a version with aluminum-doped core for increased SBS threshold. All are available with wide range dispersion values.
