MikroTik DQ+BC0003-DS+ 200G QSFP56 to 4×50G DAC Breakout Copper Cable (3m)

Overview:

The MikroTik DQ+BC0003-DS+ (ST02057) is a 3-meter high-speed DAC (Direct Attach Copper) breakout cable that splits a single 200 Gigabit QSFP56 port into four independent 50 Gigabit connections. Designed for full compatibility with next-generation 200G and 400G platforms, it maximizes port utilization on switches such as the CRS812 DDQ and CRS804 DDQ.

Description:

The MikroTik DQ+BC0003-DS+ is a QSFP56 breakout copper cable engineered to meet the high-density connectivity demands of data center and enterprise network infrastructures. It features a QSFP56 200G connector on one end and four independent SFP56 50G connectors on the other. This architecture allows a single 200G port to be distributed across four separate 50G devices or uplinks, eliminating the need for additional hardware and enabling the most efficient use of port capacity.

While retaining the breakout capabilities of its predecessor, the XQ+BC0003-XS+, the cable also supports next-generation speeds: it can split 100G into 4×25G, 40G into 4×10G, and 200G into 4×50G. This broad compatibility range enables flexible 200G/400G port deployments on platforms such as the CRS812 DDQ and CRS804 DDQ without complex configurations. Its 3-meter length provides the reach required for server room and in-rack connections while supporting a neat and organized cabling infrastructure.

Key Highlights:

• QSFP56 200G to 4× SFP56 50G breakout connectivity
• Supports splitting 100G into 4×25G and 40G into 4×10G
• 3-meter length for flexible in-rack placement
• Full compatibility with CRS812 DDQ and CRS804 DDQ platforms
• Ideal DAC solution for high-density port utilization
• High reliability with approximately 100,000 hours MTBF (@25°C)
