Abstract: Control of fiber sensing is provided for optical fiber networks. A Bidirectional Sensing Control Devices (BSCD) is placed at each of one or more selected locations in the network. The BSCD uses a directionally selective optical coupling element to separate the two propagation directions of a bidirectional fiber, so that on the side of the coupling element distal to the bidirectional fiber, one unidirectional fiber will carry transmissions inbound to the coupling element, and another unidirectional fiber will carry transmissions outbound from the coupling element. Sensing control can then be effectuated on one or both of the unidirectional fibers without interrupting communication in either propagation transmission direction.

Abstract: Various example embodiments of optical nodes may be configured to support improved connectivity between optical fibers and/or cores of optical fibers connected to the optical nodes based on use of various optical cross-connect architectures within the optical nodes. Various example embodiments of optical nodes configured to support use of various optical cross-connect architectures within the optical nodes in order to provide improved connectivity within the optical nodes in a manner that supports improved connectivity between optical fibers and/or cores of optical fibers connected to the optical nodes may be configured to support optical cross-connect architectures that increase connectivity between middle stage switches of the optical nodes (e.g., use of an auxiliary optical switch to increase connectivity between middle stage switches, use of connections between middle stage switches to increase connectivity between middle stage switches, or the like, as well as various combinations thereof).
