PTT5101D

Detailed Product Description

PTT5101D is a high performance forward path transmitter.19 inches rack mount structure, high linearity and low noise 1550mm DFB laser and state of the RF control circuits, pre-distortion, these make PTT5101D a desirable choice for metro HFC network.

PTT5101D uses 1550nm DFB laser with high linearity and low noise. Pre-distortion circuit improves the performance and stability of DFB laser. AGC/ATC mechanism provides protection to laser and ensures the performance and stability module and feedback to intelligent system platform. This ensures the laser to work at normal status and high performance. If the laser operating parameter out of specification that is set by software, it will set-off the lasers power supply, and display the information on the front panel LCD
