For Cost-effective Analog SATCOM IF Applications  


The INST/INSR-1401 system consists of the INST-1401 transmitter and INSR-1401 receiver. The system utilizes linear intensity modulation to transmit SATCOM and similar microwave IF signals over distances of several miles.

The system operates with standard single-mode optical fiber and installation only requires a simple one-minute gain adjustment. In additional, integral LEDs are provided on both units to continuously indicate the presence of repetitive signals as well as the presence of operating power making system troubleshooting simple.
