Patent number: 10736227Abstract: The solution of the present disclosure connects the power in parallel distribution chains. A horizontal pizza box in the middle of the equipment stack represents the power box (PB), which houses the power modules (PMs), such as the power input modules (PIMs) or the power supply units (PSUs). The PMs in the PB are connected to the office power source(s), and the PB supplies power to the parallel distribution chains (A? and B?). The parallel distribution chains are composed of jumper segments that are based on busbar-like technology, with each jumper segment being the length of the distance between coupled boxes. Any box can be removed without disrupting either distribution chain. Advantageously, the jumper segments are touch-proof, from a safety perspective. Thus, instead of a jumper created using a cable, PCB, etc., or a jumper composed of a custom molded back-to-back connector, the jumpers are based on busbar-like technology.Type: GrantFiled: May 13, 2019Date of Patent: August 4, 2020Assignee: Ciena CorporationInventors: Daniel Rivaud, Andrew L. Jarabek, Anthony Mayenburg, Fabien Colton
