Product ManualManual
  • Single card demultiplexer for four synchronous or asynchronous 270Mb/s SDI, SDTi or DVB-ASI video signals
  • Accepts SMPTE ST 292-1 signal from companion 7708VT-4
  • Low jitter SDI outputs
  • Independent signal outputs unaffected by loss of any other SDI or DVB-ASI input feed
  • Transparently passes embedded AES or any other data in the horizontal or vertical ancillary data space
  • 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
  • SC/PC, FC/PC connector options
  • Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK®
  • 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.
