Zusammenfassung:This application discloses an optical backplane system, a switching system, and a switching system upgrade method. The optical backplane system includes a first upper-level optical interconnection module, a first lower-level optical interconnection module, and a second lower-level optical interconnection module. The first upper-level optical interconnection module includes M1 first interfaces and N1 second interfaces in connection relationships. The first lower-level optical interconnection module includes L1 third interfaces and K1 fourth interfaces in connection relationships. The second lower-level optical interconnection module includes L2 third interfaces and K2 fourth interfaces in connection relationships. The first upper-level optical interconnection module is connected to one of the L1 third interfaces of the first lower-level optical interconnection module by using one of the N1 second interfaces. The first upper-level optical interconnection module is connected to one of the L2 third interfaces of the second lower-level optical interconnection module by using another one of the N1 second interfaces. All the first interfaces and the fourth interfaces are configured to connect to processing modules. All M1, N1, K1, K2, L1, and L2 are greater than 1.
