مشخصات کلی:

Using 32-bit high-performance ARM processor, together with a complete automatic monitoring system circuit, ensure a stable optical output power and ensure that the laser is in the best working environment

A good modulator servo system and a unique “wind pendulum” mode of operation of the modulator phase tracking system provide a more accurate and delicate control process

Using a microwave source programmed and controlled by the CPU, the frequency and amplitude of the signal can be dynamically adjusted to generate microwave signals of any frequency and amplitude with less harmonics. The SBS threshold range is 13-19dBm

External modulation technology has no ripple effect, very low dispersion distortion, and has good characteristics in the band. The working bandwidth is 47~1000MHz

RF digital signal predistortion system can precisely match the predistortion amount according to the signal strength and modulation amplitude to ensure the signal quality

LiNBo3 external modulators perform signal modulation to ensure improved optical power into the fiber and increase transmission distance when the system COS performance index is excellent

The RF gain is selectable in AGC/MGC mode and the OMI±7dB range is adjustable

Blue and white 144*32-point LCD display on the front panel, which can accurately display all working parameters and fault information of the equipment

Hot-swappable dual power supply, CPU assignable power, 48V or 220V optional
