Backplane Test, 10GBASE-KR

The throughput of many racks of communication equipment is limited by the backplane bottleneck. Often the hardest part of a system to upgrade cost-effectively, there is a lot of effort going into squeezing more bandwidth out of legacy backplanes. This isn't trivial, when some were designed for 1.5 Gb/s and are now expected to function with upgraded line cards at 3 or even 6 Gb/s. Effort is also going into 10 Gb/s and higher, mainly aimed at new rack installations. Pre-emphasis and equalization are frequently employed to overcome backplane frequency response effects.
