ABSTRACT:
A communication system include a communication unit comprising first and second optical interfaces 2 and 3, a lower order interface 4, an active selecting circuit 5, and a spare selecting circuit 6. The active selecting circuit 5 include a selector 13 which selects one of transmission signals from the first optical interface and a selector 17 to supply the one of transmission signals to a active transmission path 10 of the lower order interface 4. The spare selecting circuit include a selector 15 and the selector 17. The selector 15 selects one of transmission signals from the first optical interface and the selector 17 to supply the one of transmission signals to a spare transmission path 11 of the lower order interface 4. The selector 17 is connected to input and output terminals 19 and 20 connected to each other. The selector 17 selects transmission signal from the first optical interface to supply the transmission signal to the selectors 13 and 15. The communication system may comprise first and second communication units each of which is similar to the communication unit. The output terminal of the first communication unit is connected to the input terminal of the second communication unit. In addition, the input terminal of the first communication unit is supplied with a transmission signal from a spare communication unit.
