LN-4332Z4 Leaf/Spine switch – delivers unprecedented 32xQSFP56-DD 400Gpbs ports in single rack unit of space – is ideally suited for deployment where high performance is the most important, or, with 12.8Tbps total performance – as an ultra-powerful appliance.
LN-4332Z4 is primarily packaged to meet the requirements of deployments that require smaller form factor and access to all network ports and management ports from the front side of the product. It provides total of 32x400GbE + 2x10GbE ports.
In order to be able to fit all access, uplink and data ports on the front side of a 1U system, all data plane connectivity to LN-4332Z4 is provided through QSFP56-DD sockets. Each QSFP56-DD socket can operate as a single 400GbE port, or with a break-out splitter cable a number of up to eight lower speed ports. QSFP56-DD sockets support 400GBASE-SR8, 400GBASE-FR8, 400GBASE-LR8, 400GBASE-ER8 and 400GBASE-DR4 physical interfaces.
