Submarine observation apparatus and submarine observation system |
摘要 |
In each of a plurality of submarine observation apparatus ( 1 to n), a branching unit ( 63 ) branches fixed-wavelength light (lambda 1 ) from an incoming wavelength-multiplexed light signal. An observation signal modulating unit ( 64 ) modulates the intensity of the branched fixed-wavelength light (lambda 1 ) with observation information multiplexed by an observation signal multiplex unit ( 61 ). A combiningunit ( 65 ) combines lightsignals (lambda 2 ) to (lambdan) passing through the branching unit ( 63 ) and the fixed-wavelength light (lambda 1 a) modulated by the observation signal modulating unit ( 64 ) into a composite light signal, and outputs it to an optical fiber ( 12 a). Therefore, in each of the plurality of submarine observation apparatus ( 1 to n), there is no necessity for providing a wavelength-division-multiplexing-transmission optical transmitter which requires high wavelength stability.
