With its remarkable spectral density stability, the cost-effective FLS-2300B from EXFO is an excellent source for fast and reliable characterization of high-loss DWDM passive components such as thin film filters, arrayed waveguides and fiber Bragg gratings. With the FLS-2300B there is no need to perform a reference at every measurement, which saves you time on the production floor.



When compared to LED, super-LED or other ASE sources available on the market, the FLS-2300B has the highest power density. The result—a higher dynamic range when measuring a passive device with an optical spectrum analyzer. Make use of the wide wavelength range from 1530 nm to 1600 nm with the high spectral density of –8 dBm/nm.



High Output Power and Excellent Flatness

The FLS-2300B ASE Broadband Source is a high-power, unpolarized fiber-optic source that is ideal for component testing, PMD measurements, communication link characterization and fiber sensing. By optically pumping an erbium-doped fiber, the C- + L-band source emits a flattened amplified spontaneous emission (ASE) spectrum over the entire wavelength range. Its unpolarized output makes it ideal for stable and average loss measurements.
