ANALYSIS OF METHODS AND PROTOCOLS FOR ORGANIZING LONG-DISTANCE WIRED COMMUNICATION

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.

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.
