or so should be fine with the standard flat grey stuff. The coupler

limit the length to 25'
I had a set that worked of flat with a copper shield that worked that was
50' long, but only for a 25 ips drive. (Pertec). I had some made by
Pertec for their 7000 series drives that were 25' long as Al described,
that had no shield.
I never observed a difference between the ribbon cable or the braided
ones at 25 to 75 ips. I never had to run a long run with a Cipher, which
was the main drive I ran a 100ips, as all I had the luck to work with were
in the cabinets with the systems, and long cables (over 20' or so) were
not necessary.
