A backplane or backplane system is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus.

EXTENDING THE REACH OF PASSIVE COPPER IN BACKPLANE, MIDPLANE AND OVERPASS CABLE APPLICATIONS. Cable Backplane Systems is part of Amphenol's Highspeed Backplane Product business, dedicated to developing and manufacturing cabled backplane solutions for next generation system architectures.

100 Gb/s Backplane and Copper Cable Task Force. The task force is standardizing Ethernet at 100 Gb/s over a 4-lane backplane channel as well as across a 4-lane copper cable. We first describe the background of the market drivers for this technology, and then give an overview of the various technologies that are used to solve

This article provides an overview of some of the work that is ongoing in the IEEE P802.3bj 100 Gb/s Backplane and Copper Cable Task Force. The task force is standardizing Ethernet at 100 Gb/s over a 4-lane backplane channel as well as across a 4-lane copper cable.

This paper describes techniques and key parameters for designing long-distance path of 10 Gbps signal transmission in copper backplane system. First, two connecting modes for copper backplane have been presented. And then, some materials and connectors used in high speed PCB are clarified.

in today’s backplane, we see layers of Copper, whose characteristics mostly determine how many Gbps can be switched. Going Faster “Going faster” in a Copper back-plane entails any combination of the following: • Making the Copper thicker; • Making the dielectric layer thin-ner; • Using dielectrics with lower loss tangents;

§ Extends the reach of passive copper for next generation real world system designs; complementary with direct orthogonal designs, intermatable with existing board
