Abstract

We have developed a non–destructive technique for launching or observing the propagation constants of individual modes in high order multimode fibres, and hence deducing the bandwidth, V value and most other important parameters. This is done by observing light 'leaking' from the fibre through the cladding, The following is an explanation of how this works.
