Coaxial Cable Belden 1855ENH 75 Ohm SDI coax cable, 1855ENH.01500

Belden 1855ENH is a 75 Ohm SDI coaxial cable engineered for digital video signal transmission in broadcast and professional AV environments. The cable maintains a consistent 75 Ω characteristic impedance to ensure impedance matching for SDI signals, minimizing reflections and preserving signal integrity across coax runs. It is intended for connecting cameras, monitors, routers and other SDI-capable equipment where stable high-frequency performance and low loss are required.

Advantages

The 75 Ohm construction and precision impedance control deliver reliable SDI performance with reduced signal degradation over distance. The cable's shielding and conductor design support high-frequency transmission with minimized interference, maintaining picture quality for HD, 3G-SDI and similar digital video formats. Flexible jacket materials and robust mechanical build facilitate routing and installation in studio and field workflows while offering long-term durability.

How to use

Strip the cable ends according to the connector manufacturer's instructions and terminate with compatible SDI BNC or other required connectors. Route the cable avoiding sharp bends and sources of strong electromagnetic interference. Use appropriate strain relief and secure connections at both ends to maintain impedance continuity and prevent mechanical stress that could affect signal quality.

Recommendations

For best results use connectors and patching hardware designed for 75 Ω SDI systems, minimize unnecessary cable length to reduce attenuation, and test runs with appropriate SDI test equipment after installation to confirm signal integrity.
