The mini-3GHD series is a miniature, fiber optic 3Gb/s SDI digital video transport system, supporting the 1080p 3Gbps SDI format. The standard Mini-3GHD system is designed to transport one (1) channel SMPTE-424M 3Gb/s SDI, SMPTE-292M HD-SDI or SMPTE-259M SDI serial digital video signal over long distances. The Multimode version can travel approximately 1000 feet while the Singlemode version (featured) can travel significantly further at 22 miles. These are typical distance coverage figures. The maximum distance coverage may be greater than these typical numbers, depending on fiber type, fiber bandwidth, connector splicing losses, chromatic dispersion, environmental factors, etc.
