7707IFTA

70/140Mhz IF Fiber Transmitter

Product ManualManual
  • VistaLINK® enabled

The 7707IFTA is a VistaLINK® capable fiber optic transmitter for 70/140MHz IF signals. The 7707IFTA accepts one 70/140MHz coaxial input and provides a fiber optic output signal at 1310nm, 1550nm, CWDM or DWDM wavelengths. An additional electrical output is also provided for monitoring or further signal distribution. Monitoring and control of card status and parameters is provided locally at the card edge and remotely via VistaLINK®.

The 7707IFTA 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
  • 30-200MHz bandwidth
  • Wide dynamic range RF input (-5 to -65dBm)
  • Protocol transparent - transmits all video, audio and data modulation formats
  • Supports manual and automatic gain control on IF input
  • Additional electrical output for monitoring or distribution
  • Available with BNC or F-Type connector options
  • Available with output wavelengths of 1310nm, 1550nm, CWDM (ITU-T G.694.2 compliant) and DWDM (ITU-T G.694.1 compliant)
  • Supports single-mode and multi-mode fiber optic cable
  • Available in SC/PC, ST/PC, FC/PC and APC connector options
  • Fully hot swappable from front of frame
  • Comprehensive signal and status monitoring via four digit card edge display or remotely through SNMP and VistaLINK® capability
