MikroTik DQ+BC0003-DS+ 200G QSFP56 Breakout Cable 3m
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 DQ+BC0003-DS+ is a high-performance QSFP56 to 4×SFP56 direct-attach breakout cable engineered for modern high-density network environments. At 3 metres in length, it provides enough reach to connect equipment across a rack or between adjacent racks while keeping cable management clean and organised.
As the direct replacement for the XQ+BC0003-XS+, the DQ+BC0003-DS+ delivers the same great value at an identical price point — but with a significant capability upgrade. The key addition is native support for 200G to 4×50G breakout, making it fully compatible with MikroTik's latest generation of high-density switches, including the CRS812 DDQ and CRS804 DDQ. This makes it a future-ready cabling solution for networks scaling up to 200G infrastructure.
Despite this new capability, the cable maintains complete backward compatibility with earlier speed tiers, supporting 100G into 4×25G and 40G into 4×10G configurations. This versatility means it can serve across a wide range of deployment scenarios — from existing 40G and 100G environments being gradually upgraded, to brand-new 200G high-throughput setups — without needing to replace cabling as the network evolves.
The breakout design is particularly valuable in high-density switching environments where maximising port utilisation is critical. Rather than dedicating an entire 200G QSFP56 uplink port to a single connection, the DQ+BC0003-DS+ allows that port's full bandwidth to be distributed across four separate 50G links, effectively quadrupling the number of connections available from a single switch port.
With a rated MTBF of approximately 100,000 hours at 25°C, the DQ+BC0003-DS+ is a reliable and future-proof interconnect solution for high-speed network builds.
