MikroTik CRS812-8DS-2DQ-2DDQ-RM
The CRS812 DDQ is your next leap forward – a powerful, efficient, and cost-effective way to bring 50G, 200G, and 400G connectivity into your rack.
It features a quad-core 2 GHz ARM CPU, dual-redundant power supplies, and four hot-swap cooling fans, along with 2x 10G Ethernet, 8x 50G SFP56, 2x 200G QSFP56, and 2x 400G QSFP56-DD ports.
400G used to mean expensive, complex, and out of reach – but the CRS812 DDQ changes that!
With a modern Marvell switch chip and a powerful ARM CPU, it delivers advanced routing, switching, and traffic management features trusted in millions of RouterOS deployments – now with ports up to 400 Gbps.
Where does it fit?
Top-of-rack / leaf switch with 400G uplinks to the spine
Campus core bridging 10G legacy with modern 50G interfaces
Service provider aggregation node
Labs, AI clusters, and media workflows where fast east–west traffic is critical
The CRS812 scales your network from 10 to 400G in one simple, affordable, yet managed RouterOS v7 box – no forklift upgrades needed.
With the CRS812, 400 Gigabits is no longer out of reach – it’s an affordable way to launch your network into the future while keeping your existing gear in the loop.
