1550nm External Modulated Optical Transmitter
WS-WT1500 series external modulated optical transmitter can be widely used in all kinds of medium and long distance digital and analog signal communication, the CATV RF signal will be modulate to 1550nm optical signal through this transmitter, the signal transmission is long. The application scene includes large and medium-sized cable TV. Trunk and distribution network, CWDM/DWDM system, optical fiber sensing and security monitoring system.
● 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.
