Analysis of Methods and Protocols for Organizing Long-distance Wired Communication
Year: 2026
Type: article
Abstract: The paper compares long-haul wired communication methods (TDM, DWDM), PDH, SDH and OTN systems and protocols using models of capacity, power budget, dispersion, OSNR and BER. Coherent DWDM is shown to provide Tbit/s per fiber over more than 1000 km without regeneration, while copper limits high bit rates to 1–2 km. A comparison table and technology-selection recommendations are proposed.
