Which connector is typically used for an SDI signal?

The SDI (Serial Digital Interface) signal is specifically designed for high-definition video transmission over coaxial or fiber optic cables, and it uses a dedicated connector known as the BNC connector. When referencing SDI in the context of connectors, it is common to use the term "SDI" to imply that the connector used is designed to accommodate this type of signal, most notably the BNC connector.

The importance of using the correct connector for SDI signals lies in the need for maintaining signal integrity and supporting the high data rates associated with high-definition video transmission. BNC connectors provide a reliable connection and are widely used in professional video equipment for this reason.

While XLR, HDMI, and USB-C connectors serve different functions in audio and video signal transmission, they are not specifically designed for SDI signals. XLR is primarily used for audio, HDMI is used for consumer video devices, and USB-C is suited for data transfer and power delivery, but it is not standard for SDI applications.
