Overview

DFB-DM-1550-4 4 GHz 1550 nm DM DFB Laser 4 GHz 1550 nm Directly Modulated DFB Laser The Optilab DFB-DM-1550-4 directly-modulated (DM) DFB laser is a cost-effective solution for 4 GHz analog or 2.
5 Gb/s digital transmission.
Product Description The Optilab DFB-DM-1550-4 directly-modulated (DM) DFB laser is a costeffective solution for 4 GHz analog or 2.
5 Gb/s digital transmission of up to 100 km using traditional SMF-28 single-mode fiber.
The laser is available in DWDM ITU-T grid wavelengths between 1546 nm and 1550 nm.
The MQW DFB laser features 10 mW of output optical power, low residual chirp, and a built-in thermoelectric cooler, thermistor, and a rear-facet monitor photodiode for external optical power control.
