Infinera Corporation announced the expansion of its portfolio of metro packet-optical solutions with the introduction of the Infinera 7100 PSX-3S platform. The compact, high-density 1 rack unit (1RU) 7100 PSX-3S platform enables cost-effective access and aggregation of diverse metro traffic types, including high-speed Ethernet and 10 gigabits per second (Gb/s) and 100 Gb/s wavelength-division multiplexing (WDM). Driven by growth in metro networks, network operators continue to demand simple yet solutions that enable them to maximize revenue while lowering costs. The 7100 PSX-3S platform is purpose built to reduce operational expenses while enabling efficient delivery of a wide range of metro-based Carrier Ethernet services, including Business Ethernet, cloud connect, fixed broadband aggregation and 3G/4G mobile backhaul. As part of the 7100 Series [3] of packet-optical transport platforms, the 7100 PSX-3S leverages packet switching software capabilities deployed in leading Tier 1 carrier networks. The compact 7100 PSX-3S can be deployed as a standalone solution or as part of an integrated offering with the 7100 and mTera metro transport platforms, with end-to-end management and software-defined networking control enabled by the Infinera Transcend Software Suite.
