Metro/Regional Core Networking

The demand for capacity upgrades is high in metro and access networks. Data traffic is expected to continue to grow at more than 40 percent per year, and the metro access network is constantly being extended to reach new enterprises, data centers, base stations and local exchanges. All this traffic will end up in metro and regional core networks, creating challenges for service providers who need to keep service levels up and costs down.

Infinera’s XTM Series platform offers a cost-effective way of boosting capacity and reach while simultaneously expanding network and service flexibility in core networks. The solutions based on the XTM Series platform support up to 80 wavelengths carrying up to 100 gigabits per second (100G) per wavelength, while achieving a high level of flexibility with various amplifier, reconfigurable optical add-drop multiplexer (ROADM) and tunable optics options.

When combined with Infinera’s Packet-Optical Technology, Synchronous Digital Hierarchy (SDH)/Synchronous Optical Networking (SONET) network migration is addressed. The migration to a packet-optical network is vital for cost-effective transport of legacy as well as Ethernet-based services, providing a solid foundation for future service evolution.

The Packet-Optical Technology architecture is ideally suited for IP interconnect, as well as cost-effectively connecting edge and core routers in metro/regional core networking deployments. Implementing only the Layer 2 features required for this application allows a simpler, lower-cost solution for these requirements.

The Infinera DTN-X family also extends to metro 100G support, using the PIC-based AOFX-100 line card for classic transport services, the PXM packet switching module that supports both Carrier Ethernet 2.0 and multi-protocol label switching (MPLS) services, and the 100G-optimized XTC-2 packet-optical transport platform.
