1 1,55nm DWDM Direct FLD5F15CXA FEATURES Direct Modulated DFB Laser for WDM systems Optimized for Long Distance Transmission (Dispersion 32ps/nm) Peak wavelength to nm (C Band: to 196.2THz, 1GHz spacing) Output Power: 1mW 14pin Butterfly type package Power monitor PINPD (InGaAs), Thermistor, cooler Builtin 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 32ps/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 builtin 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 ITUT grid are available. ABSOLUTE MAXIMUM RATINGS (Tc=25 C, unless otherwise specified) Ratings Parameter Symbol Condition Min. Max.
