CATV Laser
FLD3F7CZ
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
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.
