The 7707VAT-3G is a VistaLINK® - capable fiber optic transmitter for 3G, HDTV or SDTV video and AES audio signals. This single card module accepts one 3G, HD-SDI or SD-SDI video plus four AES audio and transmits them on a single fiber. The companion 7707VAR-3G receiver converts the 3G, HD, SD and AES back to separate video and audio.
The fiber output is available in an assortment of optical wavelengths accommodating 1310/1550nm, CWDM and DWDM transmission schemes. The 7707VAT-3G 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.
