Abstract: Optical wavelength division multiplexing (WDM) devices include an optical chip having a number of waveguides therein, with a common optical fiber and single wavelength channel optical fibers optically coupled to the waveguides. Wavelength sensitive filters are disposed between the chip and the fibers, or across waveguides within the chip to reflect light at certain wavelengths and to transmit light at other wavelengths. In some embodiments, all of the fibers are located at the same end of the chip, in others the common fiber is located at one side of the chip and the single channel fibers located at another side, while in others the common fiber is located at a first side of the chip and the single channel fibers are located either at the first side of the chip or at a second side of the chip.

Abstract: Signal distribution arrangements are assembled by selecting a terminal body and a tap module combination that provides the desired signal strength at the intended position in an optical network. Each terminal body includes an input connection interface, a pass-through connection interface, a module connection interface, and multiple drop connection interfaces. Each tap module houses an optical tap having an asymmetric split ratio. Most of the optical signal power received at the signal distribution arrangement passes to the pass-through connection interface. A portion of the optical signal power is routed to the drop connection interfaces (e.g., via a symmetrical optical power splitter). The tap module and terminal body combination are selected based on the desired number of drop connection interfaces and to balance the asymmetric split ratio with the symmetric split ratio.

Abstract: Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.

Abstract: Embodiments include a power distribution access network comprising power sourcing equipment (PSE) having a hybrid power-data port and at least one remote distribution node coupled to the PSE. The PSE delivers power at a first voltage to the distribution node and the distribution node delivers power at a second voltage to a remote device. Delivery of power to the distribution nodes may be based on information from the distribution node. Other embodiments include a power distribution access network with remote distribution nodes daisy-chained together by hybrid power-data cables so that a power line and a plurality of optical lines pass along the distribution nodes. The optical lines sequentially drop off along the chain and a remainder of the optical lines is indexed at each distribution node. Remote powered devices are coupled to the distribution nodes. Each remote powered device receives power and optical signals from the respective remote distribution node.

Abstract: Components and arrangements for managing wave division multiplexing (WDM) filters of fiber optic networks. A flexible a substrate is used to fix a fiber routing scheme that corresponds to a cascading arrangement of WDM filters. The WDM filters can be packaged as a standalone unit for easier handling and splicing of fiber pigtails to the pre-arranged fiber routing scheme.
