The propagation constant of a photonic crystal fiber (PCF) can be approximated by substituting the effective V-value and NA into a formula valid for step index fibers (SIF), provided the V-value is defined with a core radius of 0.625 $Lambda@. V$PRM and NA must still be computed. Care must be taken when using expressions that implicitly contain derivatives of V$PRM or NA. The second mode is cut-off around the V-value of 4.1 or 2.55.
