EAM DFB Laser Diode, 12 GHz, 5 mW (DFB-1550-EAM-12)

Data Sheet

Product Overview

The Optilab DFB-1550-EAM-12 laser diode is a cost effect and compact laser solution for OC-192/STM-64 DWDM applications.  Consisting of a DFB laser with an integrated electro-absorption modulator (EAM), this allows for modulation speeds of over 12 GHz / 10 Gb/s applications on one 7-pin butterfly package device.  Including a thermoelectric cooler (TEC), temperature thermistor, optical isolator and a GPO RF connector, the DFB-EAM is available in ITU grid wavelengths upon request.
