摘要： An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS). Any one of the OSIS includes a receiving sub-module, an output sub-module, an interconnection fabric module and an optical switching sub-module. The receiving module is configured to receive multiple first and third upstream optical signals from first and second Optical Add-Drop Sub-systems (OADS) corresponding to the first and the second pods. The output sub-module is configured to output multiple second and fourth downstream optical signals to the first and second OADS. The interconnect circuit sub-module is configured to connect adjacent two of the OSISs and any two of the OSISs transmit a corresponding lateral transmission optical signal via a first line correspondingly. The optical switching sub-module is configured to transmit optical signals between the receiving sub-module, the output sub-module, and the interconnection fabric module.

摘要： Components of an optical communications network are described at a node of the network providing switching from one or more degrees of received optical signal routed to a plurality of receivers. The switch at the node generally includes a passive reconfigurable optical add drop multiplexer (ROADM) having drop or output ports that connector to optical channels leading to optical receivers without optical amplifiers between the ROADM outputs and the receivers. Configurations of the node and corresponding parameters are described that provide for use of lower cost components due to the absence of an array of optical amplifiers connected to the ROADM outputs.

摘要： An optical switch suitable for use in an add/drop of an optical network node having F>1 optical fiber per direction, the F fibers together carrying optical signals comprising up to N independent wavelength channels, is disclosed. The switch includes an Optical Cross-Connect (OXC) having F input ports and N output ports. F optical splitters are connected to the OXC, the input and output ports of the optical splitters defining ports of the OXC. The OXC is controllable to switch optical signals arriving at any of the F switch input ports to the input port of any of the F optical splitters such that each switch input port is switched to an optical splitter having at least as many splitter output ports as the number of independent wavelength channels received at the switch input port. A method for splitting optical signals is also disclosed.

摘要： An upgradable optical router for use in an optical switching network. In an initial configuration, the optical router includes wavelength selective switches configured to switch optical signals having WDM wavelengths positioned in a grid having exactly 100 GHz (about 0.8 nm) spacing in optical frequency, aka fixed grid. The interface ports within the optical switch include an optical splitter and optical coupler and additionally space for a second selective switch. At a later point in time, a second wavelength selective switch can be added to provide additional capabilities such as switching wavelengths positioned in a flexible grid.

摘要： An optical switch having multiple input and output ports directs any number of WDM signals, each arriving at a respective input port, to any one of the output ports. The optical switch includes an array of LC pixels, each positioned to receive a WDM signal transmitted through one of the ports, and an array of reflective elements, each associated with one of the LC pixels. The LC pixels are controlled to cause a WDM signal incident thereon to attain an attenuation state while an output of the WDM signal is being switched by an associated reflective element, such that when an output for a WDM signal is switched from a first port to a second port, the switching can be performed in a hitless manner.
