One way Ciena has simplified the deployment of 40G and 100G coherent solutions is through the integration of test-set capabilities into the transponder equipment, allowing operators to test the complete or partial network paths for 10G, 40G, or 100G services. Integrated Test Set alleviates, or even eliminates, the need for external test sets for services carried over 40G and 100G wavelengths—equipment that is costly and complicated at the higher rates. This functionality is part of Ciena's WaveLogic Photonics portfolio.
