摘要： A transmitter/receiver comprises a master rack (20, 200) and slave racks (30, 300) that can be coupled to the master rack. In the initial operation, the master rack handles a predetermined number of light-wave signals. As the demand for light-wave signals increases, slave racks are accordingly coupled without interrupting the initial operation.

摘要： An optical communication system includes an optical-signal transmission unit 1 transmitting an existing optical signal and a low-rate-signal superimposition unit 3 superimposing a low-rate signal on the existing optical signal by intensity modulation. It further includes: a low-rate-signal extraction unit 9 that extracts the low-rate signal from the existing optical signal on which the low-rate signal is superimposed and converts the extracted low-rate signal into a low-rate electric signal; an add-on optical-signal transmission unit 4 that transmits an add-on optical signal; a low-rate-signal superimposition unit 10 that superimposes a low-rate signal on the add-on optical signal by the intensity modulation based on the low-rate electric signal; and a repeater 5 that repeats the add-on optical signal on which the low-rate signal is superimposed, to a transmission destination.

摘要： The present invention relates to a satellite communication system in which the user satellite (2) and the terrestrial station (3) transmit data by way of the data relay satellite (1). The user satellite (2) and the terrestrial station (3) include FEC ENCs (24, 34)/FEC DECs (25, 35) that perform error correction encoding onto transmission data and decoding onto the reception data that is subjected to the error correction encoding, and the data relay satellite (1) includes format converting units (14, 15) that convert, based on a modulation scheme adopted for the transmission channel to the user satellite (2) and a modulation scheme adopted for the transmission channel to the terrestrial station (3), a signal received through one transmission channel to a format corresponding to the other transmission channel and thereby generate a transmission signal.
