1310nm光发射机输出1310nm波长的激光,一般都采用直接强度调制技术,其核心部件是DFB激光器组件;此外,还有电源、激光器偏置电路、激光器慢起动电路、失真补偿及驱动电路、功率控制及致冷控制电路、过载保护及过驱动保护电路、光检测电路等。在直接调制光发射机中,射频信号经过RF放大,电控衰减和预失真补偿后,直接驱动激光器,使得光
1310nm optical transmitter output 1310nm wavelength laser, are generally used direct intensity modulation technology, the core component is the DFB laser components; In addition, there are power supply, laser bias circuit, laser slow start circuit, distortion compensation and drive circuit, power control And refrigeration control circuit, overload protection and over-drive protection circuit, light detection circuit. In the direct modulation optical transmitter, the RF signal through RF amplification, electronic control attenuation and pre-distortion compensation, the direct drive laser, so that light
