Product ManualManual

The 7707VAR-HD is a VistaLINK® capable fiber optic receiver for HDTV or SDTV video and AES audio signals. This single card module outputs one HD-SDI or SD-SDI video plus four AES audio signals that have been transmitted by the companion 7707VAT-HD fiber optic transmitter.

The 7707VAR-U-HD has unbalanced audio connections and is identical to the 7707VAR-HD in all other aspects.

The 7707VAR-HD 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.


  • Supports HDTV video formats @ 1.485Gb/s
  • Supports 525/625 line component 4:2:2 SDI @ 270Mb/s
  • Provides up to 4 de-embedded AES audio outputs
  • Dolby E™ compatible
  • Local display of optical signal strength, video and audio presence, video and AES formats
  • Fully Hot-swappable from front of frame
  • 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
  • Supports single-mode and multi-mode fiber optic cable
  • Accepts any wavelength in the 1270nm to 1610nm range
