Patent ID: 7957429

Claim:
A transmission system comprising: a transmitting apparatus including: a signal divider to divide an input electric signal to generate a plurality of divided electric signals in a transmission interface format; a guarantee information adder to add guarantee information for guaranteeing a continuity of the divided electric signals to each of the divided electric signals; and a WDM signal transmitter to convert the divided electric signals to which the guarantee information is added into optical signals with wavelength different from one another to perform wavelength multiplexing on the optical signals and send the optical signals, a speed of each of the optical signals being less than a speed of the input electric signal; wherein the guarantee information adder adds a division identifier at a time of dividing the input electric signal to the divided electric signals as the guarantee information, the divided electric signals being numbered serially in order of division; a receiving apparatus including: a WDM signal receiver to receive the optical signals, separate the optical signals according to wavelengths, and convert the optical signals to the divided electric signals including the guarantee information; and a signal restorer to construct the divided electric signals in numerical order based on the guarantee information to restore the signal.
