As optical network infrastructures grew, a new optical transport network (OTN) layer over WDM network evolved, enabling more efficient convergence of mix of services such as 10/40/100Gb Ethernet, 8/16/32G FC and traditional SONET/SDH.
The OTN layer is designed to map different protocols and rates into the same 10G uplink pipe, providing high bandwidth capabilities, low heat dissipation and reduced rack space requirements, at a comparatively low cost.
OTN enables transport over longer distances with less regeneration sites by utilizing forward error correction (FEC) embedded within the OTN layer. This makes the OTN layer the most efficient and cost-effective multi service provisioning platform (MSPP) over WDM infrastructure.

The devices use standards-based, pluggable optical modules on all optical interfaces on both client and line sides. The solution meets market demands for low power consumption and rack space savings, reducing overall CAPEX and OPEX and enabling to easily and cost-effectively increase capacity of enterprise and metro networks.
