Abstract:
1. An optical transmission device for transmitting client data encoded according to an 8B/10B encoding, between a client side and an optical communication network side, said optical transmission device comprising: padding signal insertion means for inserting padding signals in an amount corresponding to a rate difference between a clock on the client side and a clock in the optical transmission device faster than the clock of the client side into the client data when client data received from said client side is to be transmitted to said optical communication network side; and clock synchronization means for controlling a clock to be used as a reference in transmitting the client data to synchronize with a clock having been used as a reference in transmitting the client data based on a ratio of the padding signals inserted in the client data when client data received from another optical transmission device connected with said optical communication network side is to be transmitted to said client side.
