Abstract
The present invention relates to an optical communication module, which includes: a first bidirectional multiplexer; a second bidirectional multiplexer; an optical fiber for connecting the first bidirectional multiplexer and the second bidirectional multiplexer to each other; one or more first light emitting devices connecting to the first bidirectional multiplexer, and operating in a first light emitting wavelength band; one or more first light receiving devices connecting to the first bidirectional multiplexer, and operating in a first light receiving wavelength band; one or more second light receiving devices connecting to the second bidirectional multiplexer, and operating in a second light receiving wavelength band; and one or more second light emitting devices connecting to the second bidirectional multiplexer, and operating in a second light emitting wavelength band. The second light emitting wavelength band includes the first light receiving wavelength band, and the first light emitting wavelength band includes the second light receiving wavelength band. The first light receiving wavelength band is different from the second light receiving wavelength band.
