Abstract: Embodiments presented in this disclosure generally relate to a ground device. More specifically, embodiments disclosed herein are directed to a grounding device for indicating whether there is proper grounding for electrical equipment. One embodiment presented in this disclosure provides an apparatus. The apparatus generally includes a lug configured to be coupled to a physical ground node, the lug having one or more bolts for coupling the lug to a surface of a plate such that the physical ground node is electrically coupled to an electrical ground node. The apparatus also includes a sensing circuit configured to detect whether the physical ground node is electrically coupled to the electrical ground node, and provide an indication of whether the physical ground node is electrically coupled to the electrical ground node based on the detection.

Abstract: A method includes mapping, by an optical transceiver, a received first OTU4 signal to a first FlexO frame without interleaving the first OTU4 signal into an ODUC signal prior to mapping the first OTU4 signal to the first FlexO frame. The method also includes communicating, by the optical transceiver, the first FlexO frame with the mapped first OTU4 signal to a coherent DSP over a first FOIC.

Abstract: A method includes detecting, by a hardware processor and over a universal serial bus (USB) Type-A connection, whether a client controller is present in a client device. The method also includes supplying power to the client device over the USB Type-A connection by selecting between one of a first power source or a second power source depending on whether the client controller is detected.
