Description

[Brief explanation of the drawing]

Fig. 1 shows an embodiment of this invention, Fig. 2 shows the configuration of an optical transceiver of this invention, Fig. 3 shows a conventional optical space propagation communication device, and Fig. 4 shows a conventional one. FIG. 2 is a diagram showing an optical transceiver in the optical space propagation communication device. In the figure, 1 is a room, 2 is an optical transceiver, 3 is an optical signal, 4 is a terminal, 5 is an optical transceiver, 6 is a host device, 7 and 8 are optical transceivers, 11 is an optical transmitter, 1
2 is an optical receiver, 13 is a transmission data line, 14 is a reception data line, 15 to 17 are optical signals of λ ₁ , λ ₂ , and λj in different wavelength bands, 18 to 20
are first, second, and j-th optical transmitters that convert electrical signals into optical signals of different wavelength bands; 21 to 2;
3 are first, second and j-th optical receivers that regenerate electrical signals from optical signals in different wavelength bands; 24;
is a majority circuit that takes a majority vote of a plurality of input data and outputs it. Note that the same reference numerals in each figure indicate the same or corresponding parts.
