摘要： A method and system is provided for cassette based wavelength division multiplexing. Higher throughput per laser “colored” transceivers are disclosed that can be multiplexed at the patch panel where an implementation may comprise a dense WDM grid that enables parts to meet “PSM4” specs natively regardless of color. The server to Tier 1 switch may utilize short reach PSM4 interconnects, at distances typically less than 500 meters. The Tier 1 to Tier 2 switch may utilize higher density per fiber. The outbound facing interface of Tier 1 switch has colored PSM4 interfaces and may have tight wavelength separation to enable PSM4 interoperability. The shuffling/multiplexing of colored modules may be configured outside the switch, where the aggregating cassette may be part of the patch panel and comprise a top of rack media converter.

摘要： A system for integrated power combiners is disclosed and may include receiving optical signals in input optical waveguides and phase-modulating the signals to configure a phase offset between signals received at a first optical coupler, where the first optical coupler may generate output signals having substantially equal optical powers. Output signals of the first optical coupler may be phase-modulated to configure a phase offset between signals received at a second optical coupler, which may generate an output signal having an optical power of essentially zero and a second output signal having a maximized optical power. Optical signals received by the input optical waveguides may be generated utilizing a polarization-splitting grating coupler to enable polarization-insensitive combining of optical signals. Optical power may be monitored using optical detectors. The monitoring of optical power may be used to determine a desired phase offset between the signals received at the first optical coupler.
