| Abstract(in English) | We discuss the theoretical and practical aspects of high symbol-rate signal optimization techniques for realizing a >1-Tbps/λ long-haul transmission system. We also review the key technologies for transmitting the high symbol-rate signal such as modulation format design, bandwidth extension techniques, and equalization schemes. We introduce our work on 1.3-Tbps/λ transmissions over 200 km in 4.2-THz full C-band 175-GHz-sapced WDM configuration with probabilistic constellation shaping (PCS), an analog-multiplexer integrated optical module, and an optical equalization (OEQ)-aided digital pre-equalization technique. |
