Rof analog broadband optical transceiver link RF Over Fiber
The R-ROFxxxxT series RF over fiber Link analog broadband optical transceiver link is a fiber optic remote transmission device specifically designed for real-time measurement of DC to 1GHz electrical signals in complex electromagnetic environments. The transmitting module features a 1 MΩ/50 Ω BNC input, which can be connected to various sensing devices (current probes, high-voltage probes or specific high-frequency measurement devices). In the transmitting module, the input electrical signal is modulated and converted into an optical signal, which is then sent to the receiving module through a single-mode optical fiber. The receiver module converts the optical signal back into an electrical signal. The optical signal transmission is regulated by automatic level control to maintain precise and constant performance, unaffected by optical loss. Both the transceiver modules support battery power supply and remote control. The optical transmission module also includes an adaptive adjustable attenuator (1:1/10:1/100:1) for adjusting the received signal level to optimize the dynamic range. In addition, when the device is not in use, it can be remotely entered into a low-power standby mode to save battery power, and the LED indicator light shows the working status.
