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 7800FC 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
