Product Manual
The 7706LR is a fiber optic receiver for extended L-Band and other signals. It accepts a fiber optic input from a companion transmitter and provides an electrical output signal. Control of the card is provided locally at the card edge via DIP switches.
The 7706LR 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
- Protocol transparent - receives all video, audio and data modulation formats
- Supports manual and automatic (AGC) gain control modes
- Two buffered RF outputs for extra signal distribution or monitoring functions
- RF output independent of optical loss (within AGC range)
- Available with BNC, SMA or F-Type connector options
- Wide range optical input (1270nm to 1610nm)
- Supports single-mode and multi-mode fiber optic cable
- Available with SC/UPC, ST/UPC, FC/UPC, SC/APC and FC/APC connector options
- Fully hot-swappable from front of frame
