HANOVER, Md. -- The Yafo40, Yafo Networks' PMD (polarization mode dispersion) compensator for 40 Gigabit per second (Gbps) networks will be trialed by Deutsche Telekom in a test of 40 Gbps optical transmission systems. The tests will include a laboratory trial on a testbed with PMD generated by Yafo's higher-order emulator and traditional PMD emulators, as well as a field trial in the DT network at Nuremberg. "Yafo Networks continues to lead the world in PMD compensation solutions," said Jeff Ferry, VP Sales and Marketing, Yafo Networks. "We are very pleased to be demonstrating the Yafo40's capabilities for DT, Europe's largest telecommunications company and one of the world's most forward-looking carriers. By overcoming PMD, the Yafo40 will open the door to 40 Gbps systems, enabling carriers to enjoy the benefits of more bandwidth, lower costs, and greater flexibility and scalability."
