EMCORE’s Model 1998 DFB cooled coaxial laser offers a high-performance solution for linear wideband fiber optic links. The 1998 is internally cooled with thermo-electric coolers already installed for high-stability with low power consumption. The 1998 DFB laser builds upon EMCORE’s long history of high-performance, leading-edge designs for CATV, wireless and high-speed digital applications. The laser diode device is packaged in a compact, hermetic cooled TOSA assembly together with monitor photodiode, thermistor, TEC and optical isolator for flexible integration into various transmitter configurations.
