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.
