Non-interrupting switching of optical communications path - by breaking optical fibre and switching to adjacent input end of outgoing optical fibre

摘要

The switching device uses a switching optical fibre (13) next to the end of the outgoing optical fibre (12), within the light cone (31) obtained in the switching gaps (33) from the light output face of the incoming optical fibre (11). The width of the switching gap is sufficient to provide a light fleck dia. equal to the dia. of the outgoing and switchinq ootical fibres (1213). The switchino is effected - KK :KK : KKK : : KKK : '. Kw to the axis of the incoming optical fibre (11). TAGEElimates need for T splice.
