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.
