Product Manual
The 7707IFRA is a VistaLINK® capable fiber optic receiver for 70/140MHz IF signals. The 7707IFRA accepts a fiber optic input from the companion 7707IFTA and provides two 70/140MHz IF output signals. Monitoring and control of card status and parameters is provided locally at the card edge and remotely via VistaLINK® capability.
The 7707IFRA 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
- Protocol transparent - receives all video, audio and data modulation formats
- Supports manual and automatic gain control (AGC)
- Two IF outputs for extra signal distribution or monitoring functions
- IF output power independent of optical loss (within AGC range)
- Available with BNC or F-Type connector options
- Wide range optical input (1270nm to 1610nm)
- Supports single-mode and multi-mode fiber optic cable
- Available in SC/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
