7705LTA
L-Band Satellite Fiber Transmitter
Replaces the 7705LT and offers improved performance and wider operating range
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. An L-Band BNC RF output is also provided for monitoring or further signal distribution.
The 7705LTA 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.
