What SR FO Means
SR designates the heavy-duty reinforced variant optimized for extreme mechanical stresses including high travel speeds, dynamic tensile loads, multiple directional changes, and torsional stress. FO indicates integrated fibre optic elements for combined power and data transmission in a single cable assembly.
