400G & 200G AI Networking

The MikroTik DDQ+DA0003 is a 400G QSFP-DD passive direct attach copper cable (DAC), 3 metres long — the longer of two DAC options MikroTik offers for the CRS812 and CRS804 400G platforms. With integrated QSFP-DD modules on both ends, it requires no transceivers, no fiber, and no power budget management — simply plug it in and achieve full 400G connectivity between devices across racks. It is the most cost-effective way to connect 400G-capable switches over inter-rack distances in a structured data centre environment.

The MikroTik DQ+BC0003-DS+ is a 3-metre QSFP56 200G direct-attach breakout cable that splits a single 200 Gigabit port into four independent 50 Gigabit (SFP56) connections. An upgraded successor to the XQ+BC0003-XS+, it retains full backward compatibility with 100G (4×25G) and 40G (4×10G) splitting while adding support for the latest 200G (4×50G) configuration. Designed to work seamlessly with MikroTik's next-generation high-density switches such as the CRS812 DDQ and CRS804 DDQ, it delivers excellent flexibility for high-speed data centre and enterprise network interconnects.

The MikroTik DDQ+DA0001 is a 400G QSFP-DD passive direct attach copper cable (DAC), 1 metre long — the shorter of two DAC options MikroTik offers for the CRS812 and CRS804 400G platforms. With integrated QSFP-DD modules on both ends, it requires no transceivers, no fiber, and no power budget management — simply plug it in and achieve full 400G connectivity between adjacent devices in the same rack. It is the lowest-cost entry point for 400G connectivity on the CRS812 and CRS804 platforms.

The MikroTik CRS804 DDQ (CRS804-4DDQ-hRM) is a compact 1U 400G switch built for AI clusters, storage fabrics, and high-speed aggregation. It features four 400G QSFP56-DD ports with flexible breakout down to 1G, dual 1G/10G Ethernet, a Marvell 98DX7335 switch chip, quad-core 2 GHz ARM CPU, 4 GB DDR4 RAM, dual hot-swap redundant power supplies, and two hot-swap cooling fans — all at 123W max power consumption. Runs RouterOS v7 with License Level 6.

The MikroTik CRS812 DDQ (CRS812-8DS-2DQ-2DDQ-RM) is a high-performance 1U rackmount aggregation switch that brings 50G, 200G, and 400G connectivity to data centres, campus cores, and service provider networks at an accessible price point. Powered by a Marvell 98DX7335 switch chip and a quad-core 2 GHz ARM64 CPU with 4 GB of RAM, it features eight 50G SFP56 ports, two 200G QSFP56 ports, two 400G QSFP56-DD ports, and two 1G/10G Ethernet ports — with full QSFP56/QSFP-DD breakout support down to 1G/2.5G/5G/10G/25G/50G. Equipped with dual hot-swap redundant power supplies, four hot-swap cooling fans, and RouterOS v7, the CRS812 DDQ is designed for top-of-rack, leaf, and aggregation roles in modern high-speed network environments.

The SYNOXX EDQD400-2QPx is a high-speed 400G QSFP-DD to 2x200G QSFP56 Direct Attach Copper breakout cable designed for short-distance, high-bandwidth network connections. It supports 400Gbps aggregate data rate using PAM4 signaling, making it suitable for data centers, high-performance computing, storage networks, telecom, and switch-to-switch interconnections.

The MikroTik G1382-0350WNA is an optional -48V DC hot-swappable power supply for the CRS804 DDQ switch. It enables the switch to draw power directly from standard -48V DC telecom infrastructure, adding flexible power input options alongside the default AC module. It can be installed or replaced while the device is running, providing additional redundancy and operational flexibility for carrier-grade, remote site, and DC-powered deployments.

The MikroTik G1394-0350WNA is a 12VDC 27.5A 350W hot-swappable replacement power supply designed exclusively for the CRS804 DDQ switch. It allows a failed or degraded power module to be replaced without shutting down the switch, restoring full power redundancy instantly. Built for data centres, enterprise racks, and labs where uninterrupted operation is non-negotiable.

The MikroTik G1251-0150WNA is a 150W hot-swappable replacement power supply designed for the CRS812 DDQ. It delivers 12V DC at 12.5A and can be replaced while the switch is running, helping maintain network uptime without restarting the device. 

The MikroTik MT-HotSwapFan-V2 is a hot-swappable replacement fan module designed exclusively for the CRS804 DDQ switch. It allows a failed or aging fan to be replaced without powering down the switch, eliminating downtime in environments where continuous operation is critical. Ideal for AI clusters, storage networks, and high-speed backbone deployments where sustained airflow and cooling reliability cannot be compromised.
