The Meridian Technologies SR-4HG-51/57ST 4-Channel Multi-Rate SDI/HD-SDI/3G Video Receiver from the ST/SR-4HD-CWDM DigiView transmitter and receiver system series, receives 4 channels of real-time SDI/HD-SDI/3G video signals over 1 single-mode fiber via an ST optical connector. Using CWDM (Coarse Wavelength Division Multiplexing) technology, the content details of each video channel are preserved by real-time reception of each video channel in a compact card format. The SR-4HG-51/57ST digital video receiver and the ST-4HD-CWDM transmitter (sold separately) when used together, provide broadcast-quality transmission of the industry-standard range of digital video data rates. No user adjustments are required, ensuring fast deployment and setup with broadcast-quality results. The entire electrical and optical subsystems are housed in a standard Meridian 1-slot card design for mounting in any venue, particularly in areas with space constraints.
