Product Overview
The Optilab DFB-4B series 4-channel DFB Laser Source is designed for laboratory applications where multiple, precise, stable and cost effective Distributed Feedback (DFB) laser sources are needed. Applications for the DFB-4B Source Bank include Dense Wavelength Division Multiplexing (DWDM), as well as component testing and qualification. With Optilab’s comprehensive inventory of high quality DFB laser diodes, DFB-4R series can be ordered from a large variety of ITU wavelengths. With its simple and intuitive front panel interface, the user can control the DFB laser source output power level and fine tune the wavelength (± 0.01 nm) via precise temperature control of TEC.
All Optilab DFB-4B products are constructed with 100% Telcordia-qualified components to ensure 15+ years of continuous operating life, backed by a three year limited warranty on complete system functionality. Our customer service team provides technical support for any inquires for the operation of the DFB-4B Source Bank.
