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.
