The DSA-EDFA family of optical amplifiers is optimized for extending the reach of DWDM for multi-wavelength systems to over 100 km. The low noise figure ensures meeting the most stringent Carrier-to-Noise Ratio (CNR) requirements that are encountered in RF video signal delivery. Unparalleled distance and performance is achieved when combined with the Chromadigm chirp-free high OMI transmitters to reach outlying serving areas. DSA optical amplifiers incorporate interstage dispersion compensation of 10-50 km in 10 km steps to achieve an industry best noise figure. This enables ATX-designed optical links to achieve the highest possible performance.
