    摘要： A network device of is a network device that transfers frames by repeating, in a constant cycle, a reserved transfer interval and a free transfer interval. The network device includes a transmission port, a cycle timer, a mode switching control unit that monitors a transfer state of the transmission port and selects a store-and-forward system when the transmission port is in the transfer process and selects a cut-through system when the transmission port is not in the transfer process, and a transfer prohibition control unit that selects the cut-through system as a transfer system when a non-reserved frame is transmitted and switches a transfer method of the non-reserved frame to the store-and-forward system when a reserved transfer interval is established, with reference to the cycle timer.

    摘要： In each of a plurality of submarine observation apparatus (1 to n), a branching unit (63) branches fixed-wavelength light (λ1) from an incoming wavelength-multiplexed light signal. An observation signal modulating unit (64) modulates the intensity of the branched fixed-wavelength light (λ1) with observation information multiplexed by an observation signal multiplex unit (61). A combining unit (65) combines light signals (λ2) to (λn) passing through the branching unit (63) and the fixed-wavelength light (λ1a) modulated by the observation signal modulating unit (64) into a composite light signal, and outputs it to an optical fiber (12a). 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.
