Detailed Product Description

 

CATV 1310 Optical Transmitter use in DFB butterfly 1310mn laser, low noise, dual IC, optical power 2db-15dbm. RF input:70-85db

1310 Optical Transmitter

 

PTT2103E is a high performance forward path transmitter.19 inches rack mount structure, high linearity and low noise 1310mm DFB laser and state of the RF control circuits, pre-distortion, these make PTT2103E a desirable choice for metro HFC network.

PTT2103E uses 1310nm 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.
