Optical Transport Network: Enabling High-Capacity Data Transmission

Optical Transport Network or OTN is a standard-based transmission protocol that uses optical networking techniques to address transmission requirements of service providers in transporting client signals. OTN uses Wavelength Division Multiplexing (WDM) and Synchronous Digital Hierarchy (SDH) or Synchronous Optical Networking (SONET) framing to provide flexible and robust transport of client signals.
