Publication number: 20200163242Abstract: Scalable-bandwidth aggregation boxes are disclosed that allow scalable electrical connection bandwidth of multiple servers in a rack to aggregation modules and compact bifurcatable optical cables to connect the aggregation modules to switches, while minimizing switch faceplate connector area requirements by using optical connectors. Users of a system including scalable-bandwidth aggregation boxes can choose a desired bandwidth cable to connect a server to a switch via an aggregation box. An aggregation box may include a scalable-bandwidth electrical connector on a faceplate, signal lines coupled between the scalable-bandwidth electrical connector and a board connector in the housing, and a serviceable bandwidth-aggregation module removably disposed in the housing.Type: ApplicationFiled: November 15, 2018Publication date: May 21, 2020Inventors: Kevin Leigh, John Norton
