L-Band Satellite- Fiber Optic Transmitters/Receivers


The 7705LTA is a fiber optic transmitter for L-Band satellite signals. The 7705LTA accepts one L-Band coaxial input and provides a fiber optic output signal at 1310nm. A buffered output is also provided for monitoring or further signal distribution.

The 7705LR is a fiber optic receiver for L-Band satellite signals. The 7705LR accepts a fiber optic input from the 7705LTA and provides two L-Band RF output signals.

The 7705 cards occupie one card slot and can be housed in either a 1RU frame which will hold up to 3 modules, a 3RU frame which will hold up to 15 modules or a standalone enclosure which will hold 1 module.
