MikroTik DQ+BC0003-DS+ – QSFP56 200G to 4×50G Breakout Cable for Datacenter Infrastructure

The MikroTik DQ+BC0003-DS+ is a QSFP56 200G to 4×50G breakout cable engineered for datacenter and ISP infrastructures operating on 200G and 400G switching platforms. It is used to maximize port density in high-density rack environments, splitting a single physical port into four independent connections without additional hardware or conversion modules.

The cable breaks out a single 200 Gigabit QSFP56 port into four independent 50 Gigabit channels, effectively doubling connection capacity compared to standard point-to-point configurations. Extended compatibility covers 100G to 4×25G and 40G to 4×10G breakout scenarios, providing full flexibility for mixed infrastructure environments and phased migrations from previous equipment generations. The 3-meter length is optimized for intra-rack and short-reach inter-rack connections, keeping cable management clean and signal loss negligible.

The DQ+BC0003-DS+ is natively compatible with MikroTik CRS812 DDQ and CRS804 DDQ switches — platforms built around 200G and 400G ports for maximum-density traffic aggregation. Integration into existing infrastructure requires no software reconfiguration, as the passive DAC cable operates at the physical layer without latency introduced by optical or electrical conversion. Eliminating the need for separate transceivers reduces per-port cost and simplifies component inventory management in multi-port server room deployments.

Recommended for ISP operators and datacenter infrastructure teams building or expanding leaf-spine topologies on next-generation MikroTik switching platforms. It suits environments where 200G or 400G ports must be efficiently distributed across multiple 50G clients, and for network integrators standardizing on the CRS DDQ platform to achieve maximum connectivity density at optimized cost per port.
