IRGT/IRGR-7001     DC Time Code (Unmodulated DCLS)    IRGT-7001 Digital Time Code Fiber Optic Transmission System
For High Quality DC Time Code Point-to-Point Signal Transmission  

Digital Time Code Fiber Optic Transmission System   


The IRGT/IRGR-7001 system consists of the IRGT-7001 transmitter and IRGR-7001 receiver. Both units are designed for the transmission of high quality un-modulated DCLS DC time codes from 1 pulse per second through 10,000 pulses per second in accordance with conventional IRIG derived time codes (IRIG-A through H) 

Transmission distances of more than 10Km (6.3 miles) is achievable and installation is adjustment free. In addition, integral LEDs are provided on both units to continuously indicate the presence of TTL signals as well as the presence of operating power making system troubleshooting simple.
