AB  - &lt;p&gt;The nonlinear coefficient of the various optical fibers types has been experimentally and with OptSim 5.0 simulation software studied. With the help of CW SPM, P-SPM and XPM measuring methods the following parameters have been determined experimentally: nonlinear coefficient &lt;em&gt;n&lt;sub&gt;2&lt;/sub&gt;/A&lt;sub&gt;eff&lt;/sub&gt;&lt;/em&gt; and nonlinear refractive index &lt;em&gt;n&lt;sub&gt;2&lt;/sub&gt;&lt;/em&gt;; accordingly, &lt;em&gt;n&lt;sub&gt;2&lt;/sub&gt;/A&lt;sub&gt;eff&lt;/sub&gt;&lt;/em&gt; is calculated to be in the range 1.24·10&lt;sup&gt;-12&lt;/sup&gt; - 5.26·10&lt;sup&gt;-10&lt;/sup&gt; 1/W, whereas &lt;em&gt;n&lt;sub&gt;2&lt;/sub&gt;&lt;/em&gt; − in the range 3.38·10&lt;sup&gt;-23&lt;/sup&gt; - 4.21·10&lt;sup&gt;-20&lt;/sup&gt; m&lt;sup&gt;2&lt;/sup&gt;/W. As seen from results the OS2 fibers have smaller variation of nonlinear coefficient values at different measurement methods in contrast to SSMF and DSF fibers. OS2 fiber &lt;em&gt;n&lt;sub&gt;2&lt;/sub&gt;&lt;/em&gt; value stability are in the limits from 2.88·10&lt;sup&gt;-20&lt;/sup&gt; m&lt;sup&gt;2&lt;/sup&gt;/W in case of P-SMP method to 2.9·10&lt;sup&gt;-21&lt;/sup&gt; m&lt;sup&gt;2&lt;/sup&gt;/W in case of CW SMP method.&lt;/p&gt;
