ROF RF modules broadband Transceiver Module RF over fiber link Analog broadband RoF link

Short Description:

The analog RoF link(RF modules) is mainly composed of analog optical transmission modules and analog optical reception modules, achieving long-distance transmission of RF signals in optical fibers. The transmitting end converts the RF signal into an optical signal, which is transmitted through the optical fiber, and then the receiving end converts the optical signal into an RF signal. RF fiber optic transmission links have the characteristics of low loss, broadband, large dynamic, and security and confidentiality, and are widely used in remote antennas, long-distance analog fiber optic communication, tracking, telemetry and control, microwave delay lines, satellite ground stations, radar, and other fields. Conquer has launched a series of RF fiber optic transmission products specifically for the RF transmission field, covering multiple frequency bands such as L, S, X, Ku, etc. It adopts a compact metal casting shell with good electromagnetic interference resistance, wide working band, and good flatness within the band.
