OSFP DCO products are based on different modulation techniques that use two polarizations of light to encode data. They can work with a wide range of wavelengths in the C-band and have advanced features for detecting and correcting signal distortions. They come in a standard OSFP shape that can plug into different devices and use a 7nm DSP chip. They can support data rates of 100 or 400 Gbps and are suitable for various network applications, such as metro, access and Cloud/DCI.
