It is a low-distortion analog RF signal E/O and O/E converter. It converts radio signals into light, transmits them through optical fibers, and then converts them back into radio signals.
The wavelength-multiplexed optical converters OAL-146JB/OAL-147JB can share signals over a single-mode fiber. They are equipped with a WDM coupler. The input and output cover an analog RF signal bandwidth of 70 to 200 MHz, allowing them to be connected to the transmitting and receiving ends of wireless devices for long-distance transmission as optical repeaters. They can be used as optical RoF for indoor base station wireless relay equipment.
