The 'fibre fuse' thermal damage effect can destroy kilometres of fibre at relatively modest laser powers. A low-loss tapered region strategically placed in a single-mode fibre can act as a thermal circuit breaker. thereby halting the damage propagation and protecting the fibre 'upstream' from the taper.
