MikroTik CRS812-8DS-2DQ-2DDQ-RM 400G Cloud Router Switch with 50G SFP56, 200G QSFP56 & RouterOS v7

MikroTik CRS812-8DS-2DQ-2DDQ-RM 400G Cloud Router Switch with 50G, 200G and 400G Ports

The MikroTik CRS812-8DS-2DQ-2DDQ-RM, also known as the CRS812 DDQ, is a high-performance 1U Cloud Router Switch designed for modern high-bandwidth networks that require 50G, 200G, and 400G connectivity. Built for top-of-rack deployments, campus core networks, service provider aggregation, AI clusters, storage systems, media workflows, and high-speed east-west traffic, the CRS812 brings serious switching capacity to MikroTik RouterOS environments.

The CRS812-8DS-2DQ-2DDQ-RM includes 8 x 50G SFP56 ports, 2 x 200G QSFP56 ports, 2 x 400G QSFP56-DD ports, and 2 x 10G Ethernet ports. This port mix allows network engineers to bridge legacy 10G connectivity with modern 50G, 200G, and 400G uplinks without turning the rack into a museum of adapters and bad decisions.

Powered by a quad-core 2.0 GHz ARM 64-bit CPU, 4 GB RAM, a modern Marvell 98DX7335 switch chip, and RouterOS v7 with a Level 6 license, the MikroTik CRS812 DDQ supports advanced switching, routing, traffic management, monitoring, VLAN, and network control features. It is built for environments that need scalable throughput, flexible port speeds, and centralized RouterOS management.

For reliability, the CRS812-8DS-2DQ-2DDQ-RM features dual hot-swap AC power supplies, four hot-swap cooling fans, an RJ45 serial console port, and a rackmount 1U design with included rackmount hardware. It is a strong choice for enterprise cores, ISP edge and aggregation layers, high-performance labs, and data center networks moving toward 400G infrastructure.
