50 Ohm vs. 75 Ohm BNC Cables
BNC describes the connector style, but not every BNC cable has the same impedance. Matching the cable impedance to the connected equipment is important for maintaining the intended signal performance.
| Impedance | Typical Applications | Common AV-Cables Families |
|---|---|---|
| 75 Ohm | SDI video, broadcast video, CCTV, word clock and compatible 75-ohm video systems | 1855A, 4855R, 1505A, 4505R, 1694A, 4694R |
| 50 Ohm | RF, wireless, communications, test equipment and instrumentation | RG58 / Belden 9201 and RG223 |

BNC Cable Frequently Asked Questions
What is a BNC connector?
A BNC is a bayonet-style coaxial connector widely used on professional video, RF, test, communications and synchronization equipment.
Are all BNC cables 75 ohm?
No. BNC connections are commonly used with both 50-ohm and 75-ohm coaxial systems. The correct cable impedance depends on the connected equipment and application.
Should I use a 50-ohm or 75-ohm BNC cable?
Professional video, SDI and word clock systems commonly use 75-ohm coaxial connections, while many RF, wireless, communications and test-equipment applications use 50-ohm connections. Confirm the required impedance of your equipment before ordering.
What BNC cable should I use for SDI video?
Use a precision 75-ohm SDI cable rated for the required signal format and transmission distance. AV-Cables offers dedicated 6G-SDI and 12G-SDI BNC cable families for professional broadcast video systems.
Do you make custom BNC cables?
Yes. AV-Cables manufactures custom BNC assemblies in specialized lengths, cable constructions, connector configurations and production quantities.
