CAMERA & FIBER OPTIC CABLES
CAMERA & FIBER OPTIC CABLES
Triaxial camera cable for permanent installation in conduit,
plenum air spaces, or outdoor environments. Gepco
triax features a precision-drawn, copper conductor
and a low-loss, gas-injected polyethylene dielectric.
These processed materials achieve low attenua-
tion, a precision 75
S impedance, low structur-
al return loss, and superior crush resistance.
Two heavy-gage, isolated braid shields pro-
vide excellent RF/EMI shielding and low DC
resistance.
