Interact with this product in a Layout Tool:


  • SDI video and 2 AES audio fiber optic receiver
  • Supports 270Mb/s on 525 or 625 line 4:2:2 component SDI and SDTi (SMPTE ST 305) video signals
  • Supports 32, 44.1, 48kHz AES audio inputs
  • Dolby E™ compatible
  • Incorporates Evertz SoftSwitch™ (Patent Pending) technology for virtually glitch-free AES Audio outputs when upstream SDI or AES feeds are switched
  • User selectable SoftSwitch™ bypass
  • Low Audio to Video latency
  • Output AES "Mute" on loss of AES or fiber optic input signals
  • SDI video regeneration for jitter reduction
  • Output Video "Black" or "Blue" (selectable) on loss of video or fiber optic input signals
  • Comprehensive signal and card status monitoring via four-digit card-edge display, or remotely through SNMP and VistaLINK® capability
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • Local display of optical signal strength, video and audio presence, video and AES formats, EDH errors
  • Fully Hot-swappable from front of frame with no fiber disconnect/reconnect required
  • Supports single-mode and multi-mode fiber optic cable
  • Accepts any wavelength in the 1270nm to 1610nm range
  • Occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
