Our SDI to Fiber units convert electrical SDI to light with a specific optical frequency - wavelength called CWDM. This way, multiple SDIs or other video or data signals could be optically multiplexed without any delay
SDI, or Serial Digital Interface, is a standard for transmitting uncompressed digital video and audio signals over coaxial cables. It's widely used in professional video production, broadcasting, and surveillance systems due to its high-quality, low-latency transmission capabilities. SDI supports various video resolutions, including standard definition (SD), high definition (HD), and ultra-high definition (UHD).
Transmitting high-speed digital video over long distances presents challenges such as signal degradation and interference. Fiber optic cables offer a solution by utilizing light pulses to carry data. Unlike traditional copper cables, fiber optics are immune to electromagnetic interference, ensuring reliable transmission over vast distances without signal degradation.
The process begins with the conversion of the SDI signal into an optical format using specialized transmitters. These transmitters modulate the electrical SDI signal into optical signals, which are then transmitted through the fiber optic cable. At the receiving end, optical receivers convert the optical signals back into electrical SDI signals, ensuring seamless integration into video production systems.
Fiber optic technology provides several advantages for long-distance SDI transmission. It offers higher bandwidth, allowing for the transmission of high-speed digital video signals, including 12G-SDI for ultra-high-definition content. Additionally, fiber optics are immune to electromagnetic interference and can span much longer distances compared to traditional copper cables, making them ideal for demanding applications in broadcasting, live events, and surveillance where reliability and signal integrity are paramount.
