To inexpensively and efficiently achieve operation verification of optical components of an optical node.

An optical node device includes: at least one first port to which a transmitter is connected; at least one second port to which a receiver is connected; at least two third ports selectively connected only to the first port at a part, and selectively connected only to the second port at the other part; and an optical transmission path for connecting a sixth port and a seventh port which are two of the third ports. A forth port which is one of the first ports and a fifth port which is one of the second ports can be respectively connected to the sixth port and the seventh port respectively.
