Abstract
A method for detecting an MPI noise problem. The method includes: receiving a first signal, where the first signal includes a service signal sent by a sending device and an MPI noise signal generated by an MPI noise generator, and the MPI noise generator is disposed between the sending device and a receiving device of the service signal; determining whether a packet loss occurs in the service signal; and when a packet loss occurs in the service signal, determining that there is an MPI noise problem in an optical fiber link between the sending device and the receiving device. Therefore, when a packet loss occurs in a service signal that passes through an optical fiber link between a transmit end and a receive end, it can be determined that there is an MPI noise problem in the optical fiber link.
