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 - 5.5 d B Link Budget Available - Suitable for Narrow Cast Configuration APPLICATIONS This DFB laser is intended for application in analog AM, CATV at 1,310nm. Transmission spans of 15 km are possible without amplification. DESCRIPTION This DFB laser for analog AM application is a middle 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 cost effective 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.
