This document defines the procedure of NFP (near field pattern) analysis of a multimode optical waveguide with rectangular core(s) with use of EF (encircled flux) analysis methodology. Circular optical fibres are out of the scope of this document.
Optical waveguides that can be connected to graded index multimode fibres (e.g. OM3, A4i, etc.) are applicable.
