Abstract
Methods and systems of a disaggregated integrated synchronous optical network (SONET) and optical transport network (OTN) switching system that includes using plug-in universal (PIU) modules for OTN to Ethernet transceiving, SONET PIU modules for Ethernet to SONET transceiving, and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules and an Ethernet over SONET module in each of the SONET PIU modules may enable various SONET and OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches.
