SDI (Serial Digital Interface) cable is a type of coaxial cable that is commonly used in the broadcast and professional video industry to transmit digital video signals. It is designed to transmit uncompressed video signals over long distances with minimal signal degradation, making it an ideal choice for high-quality video productions.
SDI cables come in various versions, including SD-SDI (standard definition), HD-SDI (high definition), and 3G-SDI (3G or higher resolution video). They are typically terminated with BNC connectors and can transmit video signals up to 300 meters (about 1000 feet) without signal loss.
SDI cables are often used to connect video cameras, video switchers, monitors, and other video equipment in a production workflow. They are a reliable and high-quality alternative to other video transmission methods, such as HDMI or VGA, as they are less prone to interference or signal degradation over long distances.
Overall, SDI cables are an essential component in the production of high-quality digital video content, as they provide a fast and reliable way to transmit high-quality video signals from one device to another.
