100G coherent DWDM solution enables transport of 100G capacity across long distances, even up to 1000km. Our OTN processors and OTN physical layers (PHYs) offer leading innovation, integration and power for Data Center Interconnect (DCI) networks. They deliver the quickest time to market and lowest R&D expense for the OEM and minimize the total cost of ownership for the service provider. In a number of applications such as campus and inter-datacenter connectivity support for distances in excess of 400. The X12/X240 products integrate 100G Gearbox functionality with Ethernet PHY and OTN framer, delivering a cost and power optimized small foot print solution. The X120/X240 are ideal for high capacity Carrier Ethernet router/switches, Packet Optical Transport systems and DWDM Transport systems. Its. Upgraded from 10G links to 100G using D7000 OTN platform with 4M4C muxponder cards. Fully compatible with existing customer switches, ensuring smooth integration without. As optical network infrastructures grew, a new optical transport network (OTN) layer over WDM network evolved, enabling more efficient convergence of mix of Ethernet and Fibre Channel services and traditional SONET/SDH. Secondly, the OTN solution employs STN6800.
