高性能电流直调激光器, 典型10GHz调制带宽, 输出功率1~10mW, 波长1550nm或1310nm可选;内部带制冷,支持城域和长途应用, 以及10GHz模拟传输.
10GHz Directly Modulated Laser Module, 1550 or 1310nm, DML
The directly-modulated laser (DML) is a cost-effective solution for 10Gbps digital transmission of up to 60 km using traditional intra-city SMF-28 single-mode fiber links. Or It is also suited for analog fiber transmission. The package contains a high-speed DFB laser chip, thermoelectric cooler, thermistor, optical isolator, and a rear-facet monitor photodiode for external optical power control.
Applications
High-speed optical fiber communication
Microwave Photonics
Analog transmission
Features
- Wide range of powers and distances
- Low drive voltage, excellent linearity
- Up to 60km transmission capability
