V8610TD is a high-performance forward path transmitter. 19-inch rack mount structure, high linearity and low noise 1550mm DFB laser, and state of the RF control circuits, pre-distortion, make V8610TD a desirable choice for metro HFC network.
V8610TD uses 1550nm DFB laser with high linearity and low noise. Pre-distortion circuit improves the performance and stability of the DFB laser. AGC/ATC mechanism protects the laser and ensures the performance and stability module and feedback to the intelligent system platform. This ensures the laser works at normal status and high performance. If the laser operating parameter is out of specification that is set by software, it will set off the laser’s power supply, and display the information on the front panel LCD.
