Originální abstrakt

Coherent optical systems are essential for global data transmission, supporting links from data centers to metropolitan networks. These systems are expected to soon deliver speeds of 1.6 Tb/s per lambda, even as slower formats like 800 Gb/s and 400 Gb/s continue to influence practices. Data modulation at 10 Gb/s has traditionally been based on on-off keying (OOK); indeed, certain non-data applications still use OOK despite the shift to coherent transmission. Our study examines the coexistence of an OOK signal and a 400 Gb/s coherent signal up to 800 km using wavelengths of 1550.12 nm and 1550.92 nm. Our findings indicate minimal impact on performance of the data signals in such scenarios for national research and education networks.
