What brand is SDI optical cable

SDI is a video interface standard, not a brand, but Belden is a leading manufacturer of professional SDI cables.

SDI (Serial Digital Interface) cables are designed to transmit uncompressed digital video signals over long distances, commonly used in broadcast and professional video setups . The term "SDI cable" refers to the type of cable meeting the SMPTE standards (e.g., SD-SDI, HD-SDI, 3G-SDI, 6G-SDI, 12G-SDI), rather than a specific brand . Belden is widely recognized as a top manufacturer of SDI cables, offering products that support legacy 3 GHz applications as well as modern 6 GHz and 12G-SDI for 4K UHD video . Their cables are considered the broadcast industry standard, providing high reliability and performance for professional video equipment. Other companies, such as Romtronic and Luminxel, also supply SDI cables, including 3G-SDI and 12G-SDI assemblies with precision connectors for studio and live production . When selecting SDI cables, consider the SDI standard (3G, 6G, 12G), cable type (RG-6 or RG-11 for coaxial, or optical variants for long distances), and shielding quality to ensure signal integrity over the required distance . Optical SDI cables are typically used for longer runs where coaxial cables may suffer from signal loss. In summary, SDI itself is a standard, and Belden is the most prominent brand producing high-quality SDI cables suitable for professional and broadcast applications .
