Description
Overview
GAOTek fiber internal optical transmitter uses a 1550 nm 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.
