FLD3F7CZ

1,310nm DFB CATV Laser FEATURES • • • • • Direct Modulation DFB Laser Built-in TEC, Thermistor and Monitor PD Optical Isolator 14 Pin Butterfly Type Module 78 Channel NTSC Loading (112 Channel device available) • Low Residual CSO & CTB • 11 dB Link Budget Available FLD3F7CZ APPLICATIONS This DFB laser is intended for application in analog AM, CATV at 1,310nm. Transmission spans of 30 km are possible without amplification. DESCRIPTION This DFB laser for analog AM application is a high power laser capable of carrying 78 channels with excellent CSO, CTB, and CNR performance. 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 a thermistor.
