Long cable runs eat your signal. In broadcast trucks, stadium installations, and large-scale CCTV backbones, video ghosting, color shift, and intermittent dropouts cost time and money — often because the cable wasn’t spec’d right from the start. The Belden 1695A solves this.This is a 75-ohm low-loss digital video coaxial cable built for HD-SDI, 3G-SDI, and ASI signal transmission. Precision-controlled impedance and dual-layer shielding keep picture clean over distance. Made in the USA, it’s the cable behind thousands of live productions, security networks, and medical imaging systems that can’t afford a single frame loss.Core Specifications

What Makes the 1695A Different Under Real Conditions
- Low loss means fewer repeaters. At 4.3 dB/100 ft at 1 GHz, HD-SDI stays clean past 300 ft without amplification. In arena video feeds or campus surveillance runs, that cuts hardware costs and eliminates failure points.
- Jacket built for abuse. The CL2P polyethylene sheath resists oil, UV, and abrasion. It bends tight in conduit and plenum spaces without kinking — a must for permanent installs in factories, outdoor OB vans, and industrial plants.
- EMI rejection where it counts. The 95% braid-plus-foil shield blocks interference from motors, VFDs, generators, and wireless gear. Plants, data centers, and stadiums with heavy electrical noise stay on-air.
- Impedance stability, no jitter. Tight 75-ohm tolerance across the full frequency range prevents signal reflections. Critical for 3G-SDI and 12G-SDI workflows where timing accuracy determines whether the picture holds or tears.
