Product introduction

The high-bandwidth direct modulated analog RF optical transceiver module (HC-ROF-HB series) can realize the long-distance transmission of high-bandwidth RF signals in the optical fiber: the transmitter converts the RF signals into optical signals, which are transmitted through the optical fiber, and the receiver converts the optical signals into RF signals. Radio frequency optical fiber transmission link has the characteristics of low loss, wide band, large dynamic range and security, and is widely used in the fields of long-distance antenna, long-distance analog optical fiber communication, tracking, telemetry and control, microwave delay line, satellite ground station, radar, etc. This series of products are specially designed for the RF transmission field to launch a series of RF optical fiber transmission products, covering L, S, X, Ku and other frequency bands, using compact metal casting shell, with good anti-electromagnetic interference, wide working bandwidth and good in-band flatness.
