As broadband networks continue to spread rapidly, notable "network migration"—that is, shifts towards fiber optics and IPs, integrated fixed and mobile networks, and the ubiquitous information society—is being forecast. Under these circumstances, future optical transport networks, which form the infrastructure that underpins the ubiquitous information society, will require solutions for lowering equipment costs as well as operation and maintenance costs across entire networks, that is, from access networks up to long-haul core networks. As regards handling a multitude of services and data traffic with constantly changing parameters, it is a great challenge to ensure flexibility. To ensure such flexibility in response to varying network traffic on optical transport networks, covering access networks up to longhaul core networks, Hitachi has introduced two optical transport platforms: the AMN7500, providing total integrated management for networks covering different areas and with different topologies, for next-generation optical transport systems; and the AMN6200, emphasizing ease-of-use in access areas, for low-capacity WDM systems.
