Abstract
The invention provides a fault positioning method and device. During fault positioning, an optical splitter is omitted, instead, only a monitoring optical port of a monitor is used to enable the far-end loopback function and finally positions a fault. The monitor receives and transmits optical signal data, so that link Down of the monitor due to that the monitor does not transmit the optical signal data for a long time is avoided. The fault source can be accurately positioned on the premise that the optical splitter is not used, and the network cost is reduced.
