Blackmagic Design Mini Converter - Optical Fiber (BMD-CONVMOF) Mini Converter Optical Fiber automatically switches between any SD, HD, 3Gb/s HD-SDI video standards and each direction can be completely independent. Mini Converters support embedded SDI and HDMI audio and several models let you separately embed or de-embed analog or digital audio. Mini Converters support 24-bit analog and AES/EBU audio and use standard 1/4in audio jacks so you don't need custom cables! You get bi-directional SDI to optical fiber conversion, with each direction independent of each other. Optical fiber cables span distances up to 28 miles without any deterioration to the signal. Unlike other converters, a universal power supply is included with international socket adapters for all countries.
