OFS Highly Non-Linear Fiber with Stable Phase-matching for Improved Nonlinear Efficiency (HNLF-SPINE) combines a high non-linear coefficient with a zero dispersion wavelength that is very stable along the fiber length. The fiber design includes a high delta core, doped with GeO2, surrounded by a deeply depressed ring doped with fluorine. The HNLF is available with zero dispersion wave from 1526 to 1543 and at 1566 nm.

Typical Applications

N/A Parametric Process


N/A Pigtailed fiber can be delivered without silicone glue. The fiber can be delivered in length from 100 – 250 m spooled with a linear strain gradient from 1000 to 100 g on a 140 x 320 mm spool for increased SBS-threshold. The straining has very little effect on the dispersion. The fiber can be delivered without pigtails on a 105 x 265 mm spool without any silicone glue. However, please note that splice loss of about 1 dB from HNLF to SSMF must be expected when splicing on standard fusion splicers.


N/A The HNLF is delivered spliced to a short (1-2 meter) Standard Single-mode Fiber (SSMF) pigtail with connectors as per request. It is delivered on a 29 x 175 mm spool covered with a protective layer of silicone glue.
