Canare L-3.3CUHD 12G-SDI Ultra Coax Custom Cable

Special 75-ohm Canare L-3.3CUHD coaxial cable for 12G-SDI / 4K-UHD in accordance with SMPTE ST 2082-1. It allows for the transmission of a 12G-SDI signal over distances of up to approximately 58 meters, depending on the equipment used and the entire signal path.

Canare L-3.3CUHD 12G-SDI Ultra Coax Custom Cable

The Canare L-3.3CUHD is a special 75-ohm coaxial cable for professional 12G-SDI / 4K-UHD applications in accordance with the SMPTE ST 2082-1 specification. It is designed for situations where a 12G-SDI signal needs to be reliably transmitted over longer distances than with standard thinner SDI cables, while maintaining a reasonable cable diameter for practical use in production, studio, or installation environments.

For 12G-SDI, the approximate maximum transmission distance is up to 58 m, depending on the equipment used, signal quality, connectors, and the entire signal path. With a diameter of 5.5 mm and a weight of 4.1 kg per 100 m, the cable is a suitable choice for 4K-UHD connections where a combination of higher transmission capacity and a relatively compact design is required.

The cable is custom-made according to the selected configuration. You can choose the desired length, available connectors, and cover color directly on the product page. This allows you to tailor the final cable to a specific camera, monitor, converter, control room, rack, or fixed installation.
