Abstract
A transmitting device coupled to a first route and a second route as communication paths on a first ring network and coupled to a third route as a communication path on a second ring network, the transmitting device includes: a first branching unit configured to branch and output signal light input from the first route to a first terminating unit and a second output unit that outputs signal light to the second route; a second branching unit configured to branch and output signal light input from the second route to a second terminating unit, a first output unit that outputs signal light to the first route, and a third output unit that outputs signal light to the third route; and a third branching unit configured to branch and output signal light input from the third route to a third terminating unit that terminates signal light and the second output unit.
