Product ManualManual

The 7707CVT-4 and 7707CVT-4-A16 are VistaLINK® - capable, composite analog video fiber transmitters for broadcast analog video and 16 analog audio signals. These card modules accept up to four NTSC or PAL analog video inputs and 16 analog audio, performs analog to digital conversion and transmits them over a single fiber. The companion 7707CVR-4 and 7707CVR-4-A16 Fiber Receivers demultiplex the signals and convert them back to analog form.

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

The 7707CVT-4 occupies a single slot whereas the 7707CVT-4-A16 occupies two card slots 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.

  • Single card fiber optic transmitter for up to four analog video and 16 analog audio signals
  • Supports both NTSC and PAL video signals
  • Broadcast quality analog video and audio performance
  • Meets or exceeds EIA/TIA RS250-C short haul specifications for analog video transport
  • Signal transport over fiber is uninterrupted by loss of input video feeds
  • Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK®
  • Supports single-mode and multi-mode fiber optic cable
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • Adjustable equalization for up to 250m of Belden 1694A coaxial cable
  • Fully hot-swappable from front of frame with no fiber disconnect/reconnect required
  • 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
