I don't think I missed the point. I was attempting to show that this
extremely cumbersome technique is not widely used in low-cost systems.
Most low-cost modules are not pigtailed. They have a front-panel
connectors. In this environment, it is much more difficult to properly
Are you suggesting that we should require a very expensive, telecom
style of construction for low-cost 10GbE ports? Remember that many
systems may be built in metallized plastic packages with front-panel
mounted non-pigtailed modules.
