Please log in for more thread options cords like this one: http://cableorganizer.com/retractable/ This seems like a bad idea as it defeats the necessary twists in a Cat5 cable. Does anyone have any resource they can point to that discusses this or speak to it directly? Thank you! | |||||||||||||

Please log in for more thread options twists, so, that means crosstalk - conversations/voltages/spikes on wires that are adjacent to other. The twists keep this talk to each dedicated pair, and any noise generated is cancelled out the other end. Regards danejasho wrote: | |||||||||||||

Please log in for more thread options I'd be very surprised if these issues were not realised and designed out at
the manufacturing process by the tech teams involved with this what surprises me more is the cost, its hellish and all you are getting is a spring loaded coil with a plastic outer. Give me a 3m piece of UTP anyday Steve > Yes this does look like a bad idea, it's a flat cable, so therefore no

Perhaps it works 'good enough' since the length appears to be limited to a few meters. | |||||||||||||
