MikroTik Accesorio Cable breakout QSFP56 200G a 4 x 50G 3m DQ+BC0003-DS+

For data centers that need to split a single 200G QSFP56 port into four independent 50G SFP56 links without adding power or latency, this MikroTik breakout cable delivers a clean, passive copper solution. Unlike active optical cables that require signal conversion, this direct attach copper (DAC) assembly keeps the electrical path purely passive, which means lower cost, zero added latency, and no compatibility headaches with standard QSFP56 and SFP56 ports. The 3-meter length is ideal for top-of-rack to server or switch-to-switch connections within the same rack or adjacent racks.

Highlights

• Aggregate 200 Gbps bandwidth split across four 50 Gbps SFP56 ends
• Passive copper construction – no power draw, no signal regeneration
• Hot-pluggable QSFP56 connector on one end, four SFP56 connectors on the other
• 100 Ohm impedance for reliable signal integrity over 3 meters
• Compliant with IEEE 802.3cd 50G Ethernet standard
• PVC jacket in black for durability and easy identification

In daily use

Deploying this cable is as simple as plugging the QSFP56 end into a compatible switch or NIC and connecting the four SFP56 ends to servers, storage, or other switches. Because it is passive, there is no firmware to update and no additional heat to manage. The 3-meter length gives you enough reach to route cleanly through cable management arms without excessive slack. The black PVC jacket resists abrasion and keeps the cable neat in dense racks. Operating temperature range of 0°C to 70°C covers typical data center environments, and RoHS compliance ensures it meets environmental standards.
