7707CVR-4 & 7707CVR-4-A16

Quad Analog Video and 16 Analog Audio Fiber Receiver

VistaLINK® enabled

The 7707CVR-4 and 7707CVR-4-A16 are VistaLINK® - capable, composite analog video fiber receivers for broadcast quality analog video and audio signals. These single card modules accept fiber optic input from their companion 7707CVT-4 and 7707CVT-4-A16 fiber transmitters, demultiplexes the signals, performs D to A conversion and outputs NTSC or PAL analog video and audio.

The 7707CVR-4 occupies one card slot while the 7707CVR-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.

Features
  • Single card fiber optic receiver for up to four analog video, 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
  • Adjustable gain, DC offset and pre-emphasis for up to 250m of Belden 1694A coaxial cable
  • Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK®
    • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
    • Fully hot-swappable from front of frame with no fiber disconnect/reconnect required
    • Supports single-mode and multi-mode fiber optic cable
    • Accepts any wavelength in the 1270nm to 1610nm range
