Abstract: A backplane consisting of segmented bus lines on a mother board with loop-through connections to active transceivers mounted on connectors to daughter boards. The transceivers isolate the interconnect to the daughter boards from the bus lines. The loop-through transmission line on the connectors preserves the impedance of the bus lines and allows the interconnect stub to the transceivers to be short, minimizing reflections and enabling high-speed backplane operation. The connectors are removable from the motherboard for repair.
