1,550nm DFB DWDM Direct Modulation Laser FLD5F7CZ-J FEATURES • Direct Modulation DFB Laser • Built-in TEC, Thermistor and Monitor PD • 14-Pin Butterfly Type Module • QAM Transmission Application • 10mW Output Power • Low Residual Chirp • Selected wavelengths according to ITU-T grid available APPLICATIONS This laser is intended for use in Dense Wavelength Division Multiplexed (DWDM) systems that employ Quadrature Amplitude Modulation (QAM) on Quadrate Phase Shift Keying (QPSK). Transmission spans up to 60 km are possible without ampification. DESCRIPTION This Laser is a high power laser capable of QAM transmission. It is packaged in a “butterfly” type module. The module employs a high efficiency optical coupling system, coupling the laser output through a built-in optical isolator into a single mode fiber pigtail. The modules also include a monitor photodiode, a thermoelectric cooler (TEC) and thermistor. This device is designed for DWDM direct modulation transmission systems. Selected wavelengths specified to the ITU-T grid are available. ABSOLUTE MAXIMUM RATINGS (Tc=25°C, unless otherwise specified) Parameter Symbol Ratings Condition Unit Min. Max.
