本电吸收调制光发射机评估板可用于诸如-NRZ/OOK 光信号的生成. 主板集成了EML激光器, 温度和功率恒定控制, 单电压供电, **小的尺寸, 较简的用户界面, 使得它非常适合实验和开发人员在实验室调试或二次开发使用, 且******.
DESCRIPTION
The EML (Electro-absorption Modulated Laser) transmitter evaluation board consists of a conventional Distributed Feed-Back (DFB) laser and EA modulator. The modulation ** is applied to the modulator section while the laser section operates CW allowing extremely low wavelength chirping. The module includes an optical isolator, monitor photodiode, thermistor and a thermo-electric cooler.
FEATURES
Dynamic extinction ratio >=10 dB
Low drive voltage
Up to 20km transmission capability
APPLICATIONS
Optical transmission
Microwave photonics
