Abstract: In general, a branching configuration used in a wavelength division multiplexed (WDM) optical communication system, consistent with an embodiment of the present disclosure, includes a branch path with two or more optical paths cross-coupled to each other to provide redundant add and/or drop channel wavelengths to a branch terminal on each cross-coupled path. Accordingly, a fault condition affecting some of the cross-coupled optical paths may occur physically downstream from the cross-coupling, e.g., within a subsea umbilical cable or associated termination equipment. However, so long as at least one of the cross-coupled optical paths remains operational, then branch terminal equipment in the branch terminal may continue to receive channel wavelengths associated with a faulted optical path via an operational optical path by virtue of cross-coupling. Thus, the cross-coupled configuration reduces or otherwise eliminates the necessity of allocating spare optical paths within the subsea umbilical cable.

Abstract: A rain shedding accessory for retractable awnings is provided. The rain shedding accessory includes a bow system for coupling between a pair of arm members of an awning structure in a mounting region located beneath an area corresponding to a leading portion of an awning sheet thereof. A bow member of the bow system is aligned generally parallel to a lead member of the awning structure and is upwardly curved to elevate a portion of the awning sheet when the awning is in a deployed configuration to prevent the accumulation of water or debris thereon. Other accessory devices and methods of preventing the accumulation of water or debris on retractable awning structures using bow systems and other prop devices are also provided.

Abstract: A bow system is provided for coupling between a pair of arm members of an awning structure in a mounting region located beneath an area corresponding to a leading portion of an awning sheet thereof. A bow member of the bow system is aligned generally parallel to a lead member of the awning structure and is configured to flex upwardly to elevate a portion of the awning sheet when the awning is in a deployed configuration to prevent the accumulation of water or debris thereon. The bow member may automatically flex as the awning structure moves from a retracted configuration toward the deployed configuration. Other prop devices and methods of preventing the accumulation of water or debris on awning structures using bow systems and other prop devices are also provided.
