Data Center Connectivity

Scalable solutions for data center interconnect (DCI)

Cloud-enabled services, 5G fixed and mobile applications, and enterprise digital transformation are demanding more and more bandwidth.  To manage this growth, data center networks are expanding in number and capacity, driving the need for higher-speed data center interconnect (DCI) solutions. Operators are adopting 100G technologies today, but will quickly transition to 400G and beyond.

This need for more connectivity between data centers requires an optical transport platform that is designed for efficiency, simplicity and scalability.  The Fujitsu DCI solution, based on the 1FINITY™ disaggregated network platform, has a simple plug-and-play configuration and pay-as-you-grow approach that lowers initial investment and operating costs. The innovative 1RU blades enable agile development and provide increased rack space utilization. An open architecture enables programmability and automation for ease of use and integration into existing OSS/BSS systems.

Solution Elements

The 1FINITY Transport platform provides maximum fiber capacity, power efficiency and density in a compact form factor designed for the operational environments of data centers.

  • The 1FINITY T100 is an 800 Gbps compact muxponder that delivers 100G or 200G coherent optical transport in metro DCI applications. In addition to Layer 1 encryption, the T100 offers zero-touch provisioning, LLDP snooping, Ethernet remote monitoring and streaming telemetry. Linux-based software offers multiple management protocols and redundant AC/DC power makes the T100 purpose-built for DCI.
  • The next-generation 1FINITY T600 is a 2.4 Tbps universal muxponder with discrete line-side optics supporting applications up to 600G wavelengths. The multi-mode T600 maintains the same features as the T100, but with larger capacity and long-haul reach, resulting in reduced cost and power factors per 100G.
  • The 1FINITY T400 is a layer 1 aggregator that supports 100 × 10GbE client interfaces. It is optimized for hyper-dense aggregation and relies upon another 1FINITY T-series blade for coherent transport.

For mesh architectures, the 1FINITY Lambda platform provides flexible ROADM functionality, supporting up to 8-degree CD-ROADM nodes, and in-line amplification for longer reach between nodes.

  • The 1FINITY L100 is a twin 1 × 9 WSS ROADM-on-a-blade that serves as a flexible bandwidth multiplexer in point-to-point applications or supports up to 128 clients in a 4-degree ROADM node.
  • The 1FINITY L110 is an optical channel management blade for add/drop of up to 32 DWDM channels into the ROADM.
  • The 1FINITY L200 is a bidirectional inline amplifier (ILA) that can be cascaded to support long ROADM spans.
