Laird 4855R10-MBMB Mini RG-59 HD-BNC Male 12G-SDI/4K UHD Belden 10-Channel Snake Cable

Product Overview

The Laird 4855R10-MBMB is a professional 10-channel 12G-SDI and 4K UHD snake cable assembly built with Belden 4855R mini RG-59 coaxial cable and terminated with HD-BNC male connectors on both ends. It is engineered to support high-bandwidth UHD video signals up to 12 GHz for demanding broadcast, studio, and live event environments.

Laird certifies this cable to operate at a maximum transmission distance of 117 ft for 12G-SDI. While Belden may list distances up to 149 ft, Laird’s transmission standard requires signal integrity to remain fully functional without any CRC errors.
