Abstract
In a network using MCF, in order to provide a technology which enables a standby system path to be easily constructed, this optical network includes: an active system path which is connected by means of a first multi-core optical fiber, and is a path between a transmission node that transmits an optical signal and a reception node that receives the optical signal; and the standby system path which is composed by means of a plurality of second multi-core optical fibers, which are different from the first multi-core optical fiber, and is a path switchable from the active system path between the transmission node and the reception node, wherein cores, which are switching destinations of the plurality of cores of the first multi-core optical fiber, are disposed at a plurality of respective unused cores of the second multi-core optical fibers.
