I need to run 250 ft. of 2 cables, and they have to be right next to
each other. I'm trying to figure out if low-voltage DC electric
interference will be an issue. Hopefully the following data is
sufficient:
Cable 1: twisted pair
15VDC at 13W
2 conductors, 16AWG: stranded bare copper, radius=0.645mm, resistance
4ohm/1000ft.
Cable 2: Coaxial
18AWG conductor: solid bare cooper, radius=0.51mm, resistance 6.4ohm/
1000ft.
Full copper braid and foil ****eld: see full specs for VSD2001 in
http://www.gepco.com/products/proav_cable/video/coax_hd_sdi_F.htm
The signal is SMPTE 292M, a.k.a. HD-SDI, carrying 70mA of 800mV peak-
to-peak, at 1.5Ghz. More detail in http://en.wikipedia.org/wiki/HD-SDI
.. I know the coax alone is fine, since the manufacturer certifies it
for 300-560ft. of HD-SDI.
I'm not expecting anyone to delve into the HD-SDI specs to figure out
exact error tolerance, I just hope to get an idea of whether I should
be worried or not. Should I go to lengths to get a ****elded version of
cable 1?
Any insight is appreciated.
