By detecting and correcting errors within the optical link, operators can increase the network span, reduce expenses, and simplify the. The Optical Transport Network (OTN) is an international standard defined by the ITU-T (International Telecommunication Union – Telecommunication Standardization Sector). It ensures data integrity, manages bandwidth allocation, and simplifies. Advantages include: Carrier-Grade Reliability OTN offers: Efficient Multiplexing Multiple lower-speed signals can be combined into higher-capacity optical channels. Scalability OTN scales from: Massive Bandwidth OTN efficiently transports terabits of traffic over a single fiber pair. Unlike SONET/SDH, OTN provides a mechanism to manage multiplexed wavelengths in a DWDM system. One of the key challenges facing OTN is the need to support increasing bandwidth.
