1. OVERVIEW
The 7707VAT series modules are VistaLINK
®
-enabled fiber transmitters for SDI Video and Audio. The
single slot 7707VAT series module is available in three versions. The module accepts one SDI Video plus
two AES (model 7707VAT and 7707VAT-U) or four analog (model 7707VAT-A4) Audio signals, combines
them using Time Domain Multiplex (TDM) technology and transmits them over a single fiber. The
companion 7707VAR, 7707VAR-U and 7707VAR-A4 modules demultiplex the signals and convert them
back to separate SDI video and AES or analog audio feeds. Throughout this manual references to the
7707VAT series include the 7707VAT-U and 7707VAT-A4 unless specifically noted otherwise.
The 7707VAT and companion 7707VAR series modules will transparently pass incoming SDI video feeds
with embedded AES audio or any other data in the horizontal or vertical ancillary data space. Minimal
audio to video latency over the transport interface is also achieved.
The fiber output is available in an assortment of optical wavelengths, accommodating standard, or CWDM
transmission schemes. For the sake of simplicity only the wavelengths for the 7707CVT are shown.

There are several versions with built in isolators specifically suited to coarse wave division multiplexing
(CWDM) applications. These versions all have 0dBm output and are suitable for distances up to 75 Km.

There are several versions with built in isolators specifically suited to dense wave division multiplexing
(DWDM) applications. The DWDM versions are suitable for distances >120 km @ 270 Mb/s (for DWDM
applications contact factory).

The 7707VAT series modules occupy one card slot and can be housed in either a 1RU frame, which will
hold up to three modules, or a 3 RU frame, which will hold up to 15 modules.
