In today's connected world, bandwidth requirements have shot up drastically due to the exponential growth in data communication. Optical Transfer Networks (OTN) today are the backbone of the tremendous amount of worldwide internet traffic. The ITU-T standards committee developed the OTN standard to address this data explosion with reliable infrastructure and low transmission costs in the optical world. OTN provides transport, aggregation, routing, supervision, and survivability of client signals processed in the digital domain and carried across the optical domain. It addresses the data explosion by mapping non-OTU signals into OTN signals and then multiplexing multiple OTN signals (referred to as Constant Bit Rate) onto a single fiber. To
