The utility model discloses an intelligence optic fibre distributor and system, include: the smooth monitoring channel module of the luminous power of real-time supervision work at present optic fibre, with light monitoring channel module is connected, works as when the luminous power is less than the threshold value of predetermined switching optic fibre, issue the smooth automatic protection module of the instruction of switching optic fibre, and with the response is connected to light automatic protection module the switching executable module of reserve optic fibre for work optic fibre is switched in the instruction of switching optic fibre. The utility model provides an intelligence optic fibre distributor and system through the luminous power of real-time detection work optic fibre, is less than the switching threshold of settlement when the luminous power value that monitor, promptly main when breaking down with optic fibre automatic switch-over reserve optic fibre extremely fast to the set a camera protection of transmission system circuit of realization.
