1,550nm DWDM Direct Modulation DFB Laser www.DataSheet4U.com FLD5F15CX-A FEATURES • Direct Modulated DFB Laser for WDM systems • Optimized for Long Distance Transmission (Dispersion 3200ps/nm) • Peak wavelength 1527.99 to 1563.05nm (C Band: 191.8 to 196.2THz, 100GHz spacing) • Output Power: 10mW • 14-pin Butterfly type package • Power monitor PIN-PD (InGaAs), Thermistor, cooler • Built-in optical isolator • Single mode fiber APPLICATIONS This laser is intended for the application of 2.5 Gb/s long haul Dense Wavelength Division Multiplexing (DWDM). Transmission spans of 3200ps/nm are possible. DESCRIPTION This high power laser is capable of 2.5 Gb/s 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 module also includes a monitor photodiode, a thermoelectric cooler (TEC), and thermistor. This device is designed for use in DWDM direct modulation transmission systems. Selected wavelengths specified to the ITU-T grid are available.
