SDI SD/HD/3G with CWDM

SDI (Serial Digital Interface) is the trusted standard for transmitting uncompressed digital video and audio in professional broadcasting, live production, and surveillance systems. Supporting SD – HD – and 3G-SDI formats, this technology ensures high-quality, low-latency video delivery across demanding workflows.

To overcome the limitations of copper cabling, SDI to Fiber with CWDM (Coarse Wavelength Division Multiplexing) enables electrical SDI signals to be converted into light and transmitted over fiber optic cables. Using CWDM technology, multiple SDI or other video/data signals can be multiplexed over a single fiber channel without delay or signal degradation.

The process involves specialized optical transmitters and receivers that convert electrical SDI into optical signals and back, guaranteeing seamless integration into any production setup. With support for high bandwidths, this technology also allows for the transport of advanced formats such as 12G-SDI for UHD and 4K video.

By leveraging fiber optics, users benefit from longer transmission distances – immunity to electromagnetic interference – higher bandwidth – and unmatched reliability. This makes SDI with CWDM the ideal solution for broadcast studios – live events – OB trucks – and surveillance systems where maintaining pristine video quality over long distances is critical.
