Retractable ethernet travel cables

Threaded View
I see a lot of people in my organization using retractable ethernet
cords like this one:

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!


Re: Retractable ethernet travel cables
Yes this does look like a bad idea, it's a flat cable, so therefore no
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.

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

That's what I thought, but there is no IEEE rating on the retractable
cable (at least it's not on the web site), but if you search the same
site for a standard 1000' box of Cat5E cable, they have all the IEEE
and EIA/TIA standards clearly identified.  Perhaps it works 'good
enough' since the length appears to be limited to a few meters.
