7707VAT-HD & 7707VAT-U-HD

HD-SDI with 4 Balanced or Unbalanced AES Audio Fiber Transmitter

VistaLINK® enabled Dolby Partner

The 7707VAT-HD is a VistaLINK® capable, fiber optic transmitter for HDTV or SDTV video and AES audio signals. This single card module accepts one HD-SDI or SD-SDI video plus four AES audio and transmits them on a single fiber. The companion 7707VAR-HD receiver converts the HD-SDI and AES back to separate video and audio.

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

The fiber output is available in an assortment of optical wavelengths, accommodating 1310/1550nm, CWDM and DWDM transmission schemes.

The 7707VAT-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.

Features
  • Supports HDTV video formats @ 1.485Gb/s
  • Supports 525/625 line component 4:2:2 SDI @ 270Mb/s
  • Supports 32, 44.1, 48kHz AES audio inputs
  • Dolby E™ compatible
  • AES audio inputs can be synchronous or asynchronous to each other and/or to input video
  • Reclocked video output for additional signal distribution or monitoring
  • Signal transport over fiber uninterrupted by loss of video or AES audio input feeds
  • Comprehensive signal and card status monitoring via four-digit card-edge display, or remotely through SNMP and VistaLINK® capability
    • Local display of input coaxial cable length equalization
    • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
    • Automatic coaxial input equalization up to 130m at 1.485Gb/s (Belden 1694)
    • Fully Hot-swappable from front of frame
    • Supports single-mode and multi-mode fiber optic cable
    • Optical output wavelengths of 1310nm, 1550nm, and up to sixteen CWDM wavelengths (ITU-T G.694.2 compliant)
    • DWDM wavelengths (ITU-T G.694.1 compliant) also available
