Abstract

An optical communications apparatus includes a branching unit and a switching module. The branching unit is configured to be connected to first, second, and third optical cables each including an optical fiber. The branching unit includes a branch optical path configured to route a fixed pre-determined range of wavelengths that are input to the branching unit from the optical fiber of the first cable to the optical fiber of the third cable. The switching module includes at least one optical switch having a bypass configuration and a branch connecting configuration. In the bypass configuration, a connection via the branch optical path to a distal portion of the third cable is bypassed. In the branch connecting configuration, the branch optical path is enabled so that the pre-determined range of wavelengths that are input to the branching unit are routed to the optical fiber of the distal portion of the third cable.
