Interact with this product in a Layout Tool:

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.
