As result of the growth trends, a new Optical Transport Network (OTN) layer evolved over WDM network enabling more efficient convergence of traditional SONET/SDH and new data services. The OTN layer is designed to for highly effective mapping of different protocols and rates into the same 10G uplink pipe providing high bandwidth capabilities, low heat dissipation, compact rack space requirements, and comparatively low cost. Furthermore, OTN infrastructure enables transport over longer distances with less regeneration sites by utilizing forward error correction (FEC) mechanism embedded within the OTN layer. Thus, the OTN layer forms the most efficient and cost effective Multi Service Provisioning Platform (MSPP) over WDM infrastructure.
