The LD-PD'S PL- DFB-C-A81-W1550-PA is a Distributed FeedBack Laser designed for Continuous Wave (C.W) operation. It is mostly utilized in combination with an external optical modulator, such as a Mach-Zehnder Interferometer (MZI) modulator. The MQW DFB laser features up to 30 mW of output optical power, high side mode suppression ratio, low RIN noise, and a narrow linewidth. The PL- DFB-C-A81-W1550-PA is housed in an industry standard 14-pin butterfly package, with a built-in thermoelectric cooler, thermistor, a back-facet monitor photodiode for conventional power monitoring, and an optional second photodiode for wavelength reference monitoring. Availabile in a wide variety of C-band wavelengths, the PL- DFB-C-A81-W1550-PA can be temperature tuned to ITU frequencies to allow for Dense Wavelength Division Multiplexing (DWDM) applications.
