Meridian Technologies ST-4HG Overview
The from the ST/SR -4HD-CWDM DigiView transmitter and receiver system series, transmits 4 channels of real-time SDI/HD-SDI/3G video signals over 1 single-mode fiber via ST optical connector. Using CWDM (Coarse Wavelength Division Multiplexing) technology, the content details of each video channel are preserved by real-time transmission of each video channel in a compact card format. This digital video transmitter provides 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 Technologies 1-slot card design for mounting in any venue, particularly space constrained areas.
