18565250908Performance characteristics
1.19 "1U standard chassis with front panel LCD display;
2.45-750/870MHz downlink bandwidth, multiple optical output powers (2-24mW);
3. Low RF input;
4. Pre distortion correction circuit;
5. Automatic Gain Control (AGC) circuit;
6. Automatic Power Control (APC) and Automatic Temperature Control (ATC) circuits;
7. RS232 interface communicates with the upper computer to achieve real-time uploading of optical transmitter operating status parameters and adjustment of electrical network management functions by the upper computer; Equipped with upper computer network management software.
8. Internal constant temperature setting, without the need for fan cooling, improves the reliability and stability of the entire machine.
