The Optilab DFB-1550D-PM​ is a single frequency laser coupled with  Polarization Maintaining fiber at 1550 nm in a standard 14-pin butterfly package for direct modulation application. Built with Distributed Feed-Back Grating (DFB) as  cavity reflector and Multi-Quantum Well (MQW) as the active layer, it provides a pure, single longitudinal mode, and extremely stable wavelength source up to 40 mW of output optical power with a high Side Mode Suppression Ratio  (SMSR). The standard 14-pin butterfly package integrates a TEC, a thermistor, a back facet power monitor PD  and an output isolator. It also integrates an inductor for laser diode bias and an impedance matching resistor for direct modulation. Contact  Optilab for more information.
