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

Rof Electro-optic modulator EDFA Optical Amplifier Erbium Doped Fiber Amplifier YDFA Amplifier
An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber. The amplification occurs in a so-called gain medium, which has to be “pumped” (i.e., provided with energy) from an external source. Most optical amplifiers are either optically or electrically pumped.
Different kinds of amplifiers differ very much e.g. in terms of saturation properties. For example, rare-earth-doped laser gain media can store substantial amounts of energy, whereas optical parametric amplifiers provide amplification only as long as the pump beam is present. As another example, semiconductor optical amplifiers store much less energy than fiber amplifiers, and this has important implications for optical fiber communications. -

Ultra Compact DP-IQ Modulator Bias Controller Automatic Bias Controller
Rofea’ modulator bias controller is specially designed for Mach- Zehnder modulators to ensure a stable operation state in various operating environments. Based on its fully digitized signal processing method, the controller can provide ultra stable performance.
The controller injects a low frequency, low amplitude dither signal together with bias voltage into the modulator. It keeps reading the output from the modulator and determines the condition of the bias voltage and the related error. A new bias voltage will be applied afterwords according to the previous measurement. In this way, the modulator is ensured to work under proper bias voltage.
