Adapt a Male BNC Cable to an HD-BNC Port
Many existing professional SDI cable runs use standard male BNC connectors, while newer high-density routers, monitors, switchers and other broadcast devices may use smaller HD-BNC ports.
This cable assembly allows the male BNC connector on an existing cable or equipment lead to connect directly to the female BNC end. The HD-BNC male end then connects to the compatible HD-BNC equipment port.
Unlike a rigid adapter, the flexible Belden 4855R cable section helps reduce mechanical stress on the equipment connector. It also provides additional routing flexibility behind crowded racks and high-density equipment panels.

Supported SDI Formats and SMPTE Standards
Belden 4855R is a professional 12 GHz Mini RG59 cable designed for compatible SD-SDI, HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI equipment.
| SDI Format | Typical Video Application | Applicable Standard |
|---|---|---|
| 12G-SDI | Single-link 4K UHD video | SMPTE ST 2082-1 |
| 6G-SDI | 4K UHD video | SMPTE ST 2081-1 |
| 3G-SDI | 1080p HD video | SMPTE 424M |

| SD-SDI | Standard-definition serial digital video | SMPTE 259M |
Total SDI Signal-Path Length
When this assembly is connected to another BNC cable, both cables become part of the complete SDI signal path. The total transmission distance includes the original cable, this adapter cable and any additional patch points or connections.
| Connected Cable | Adapter Cable | Total Signal Path |
|---|---|---|
| 25 feet | 1 foot | Approximately 26 feet |
| 50 feet | 3 feet | Approximately 53 feet |
| 100 feet | 6 feet | Approximately 106 feet |
Maximum performance depends on the SDI format, combined cable length, cable type, connected equipment, connectors, patch points and installation conditions. Contact AV-Cables before ordering for a critical or unusually long signal path.
Flexible Adapter Cable vs. Rigid Adapter
| Feature | Flexible Cable Assembly | Rigid Adapter |
|---|---|---|
| Port stress | Flexible cable helps reduce leverage on the port | Adapter and cable weight act directly on the port |
| Routing flexibility | Can be routed around adjacent connectors and equipment | Limited by its fixed shape and orientation |
| High-density installations | Better suited to crowded racks and panels | May interfere with nearby connections |
| Available lengths | Multiple short lengths available | Fixed adapter length |

12G HD-BNC to Female BNC Cable FAQs
What connectors are installed on this cable?
This cable has one precision 75-ohm male HD-BNC connector and one precision 75-ohm female standard BNC connector.
What connects to the female BNC end?
The female BNC end is designed to mate with a male BNC connector, such as the connector installed on an existing SDI cable or equipment lead.
Is HD-BNC the same as standard BNC?
No. HD-BNC is a smaller high-density connector. HD-BNC and standard BNC have different physical sizes and are not directly interchangeable.
Does this cable support 12G-SDI and 4K UHD?
Yes. This assembly uses genuine Belden 4855R 12 GHz coax and precision 12G-rated connectors for compatible 12G-SDI and 4K UHD equipment.
Can this cable carry 3G-SDI or 6G-SDI?
Yes. It is backward compatible with compatible SD-SDI, HD-SDI, 3G-SDI and 6G-SDI equipment.
Does this cable extend the total signal path?
Yes. The length of this adapter cable must be added to the length of the connected BNC cable when determining the complete SDI signal-path length.
Why use a flexible adapter cable instead of a rigid adapter?
The flexible cable section can reduce mechanical stress on the equipment port and makes routing easier behind crowded racks and high-density equipment panels.
Are custom configurations available?
Yes. AV-Cables can manufacture custom lengths, matching cable sets and production quantities for studios, broadcast facilities, production companies, integrators, government installations and OEM projects.
