> [Blue Jeans Cable] identified a cable that had sub-par signal characteristics, and without looking at the actual effects it had on network performance made the premature conclusion that it was. From the fine article: "[Our customer is] dealing with network performance issues at a small company, and has come to suspect that bad patch cords, made by an electrician, account for some of the problems he's seeing." Looks like the customer who sent them the cable had already done the troubleshooting required to determine that the cable was probably bad. Also, you should probably read: http://www.bluejeanscable.com/articles/channel-certified-ethernet-patch-cords.htm http://www.bluejeanscable.com/articles/channel-certified-eth... Each part in an Ethernet network has well-specified tolerances for a reason. If one part of that network causes far too much signal degradation then all sections of the network that flow through that part can fail to function.
