Abstract
The fibre fuse effect, also termed self propelled self focusing (SPSF) is a catastrophic damage mechanism resulting from a runaway thermal affect which can melt optical fibres. A method and apparatus for limiting the damage caused by a fibre fuse is provided by utilising a detector external to the fibre for monitoring the condition of the fibre.
