LM1 micro OTN

LM1 micro OTN

Technology
Complete solution for migrating legacy SDH/PDH networks to modern OTN/WDM infrastructures. E1 Aggregation performs the grooming of E1 services (native or channelized) into OTN (OTU1 interface), while E1 Hub has the capability to close different rings of E1 aggregators and to groom traffic over a large number of interfaces that can be legacy (SDH STM-1/4/16) or new (OTU1/OTU2). This allows a smooth migration of existing networks into modern OTN/WDM networks, simplifying the management but maintaining the services active and minimizing the traffic impact during the migration.
