OPTICAL NETWORK, NETWORK MANAGEMENT DEVICE, AND NETWORK MANAGEMENT METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18024207 titled 'OPTICAL NETWORK, NETWORK MANAGEMENT DEVICE, AND NETWORK MANAGEMENT METHOD

Simplified Explanation

The abstract describes an optical network technology that allows for the easy construction of a standby system path.

  • The network includes an active system path and a standby system path.
  • The active system path is connected by a first multi-core optical fiber and is the path between a transmission node and a reception node.
  • The standby system path is composed of multiple second multi-core optical fibers that are different from the first multi-core optical fiber.
  • The standby system path can be switched from the active system path between the transmission node and the reception node.
  • The switching destinations of the cores in the first multi-core optical fiber are located in the unused cores of the second multi-core optical fibers.


Original Abstract Submitted

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.
