Abstract: “DEVICE FOR THE SWITCHING OF REMOTE OPTICAL SWITCH PER IP ADDRESS” 12, conceived to extend the supervision distance range of centralized optical supervision systems, containing one centralized optical supervision system (COS) 5b, comprising one microcomputer that manages, through a data copper network 6b, several remote points of supervision RPS 7c, each of them formed by one OTDR, one microcomputer 3d and one optical switch 4c; and commanding, through the data copper network 6b, a plurality of remote optical switches 12, individually identified by one fixed IP address, being these remote optical switches 12 displayed in the optical fibers that are connected to the output channels of the optical switch 4c, known as optical fibers, which receive at least one remote optical switch device 12, encompassing one ETHERNET INTERFACE that receives Ethernet standard packages and performs the treatment of the TCP/IP protocol, extracting data contained in it; a microcontroller that receives and decodes data coming from t
