## Summary description

The Mikrotik XQ+BC0003-XS+ is a 3 m InfiniBand/fibre optic cable featuring a QSFP28 connector and 4x SFP28 connectors. It is designed for high-speed data transmission and reliable connectivity in networking applications.

## Long description

The Mikrotik XQ+BC0003-XS+ is a 3 m QSFP28 to 4x SFP28 break-out cable engineered for high-speed InfiniBand and fibre optic networks. Designed for data centre and enterprise environments, the cable enables one QSFP28 port to be split into four independent 25 Gbit/s SFP28 links, and it also supports dividing 40G links into 4 x 10G lines where applicable. The integrated SFP28 ends simplify deployment by eliminating the need for separate transceiver modules, while the 3 metre length provides flexible reach for racks and equipment within a server room.
Advantages
The cable offers reliable, high-bandwidth connectivity with a compact, single-cable solution that reduces the number of separate transceivers required. Built with a QSFP28 connector and four integrated SFP28 terminations, it supports multi-lane breakout scenarios, enabling efficient port consolidation and simplified cabling. The included black and chrome finish provides a neutral appearance suitable for professional installations.
Suitable for
Connecting a single 100G QSFP28 port to four independent 25G SFP28 devices
Splitting a 40G link into 4 x 10G connections
Interconnecting switches, routers, and servers in data centres or racks
Cabling between CRS504, CCR2216 and multiple 25G endpoints
Key specifications
Connector type: QSFP28 (one end) to 4 × SFP28 (other ends)
Cable length: 3 metres
Supported lane speeds: 25 Gbit/s per SFP28 lane; compatible with 10 Gbit/s lane rates for 40G breakout
Cabling type: fibre optic / InfiniBand compatible breakout cable
Colour: black with chrome accents
How to use
Insert the QSFP28 end into a compatible QSFP28 port on your switch or router and plug the SFP28 ends into the target SFP28 ports of your switches, servers or transceivers. Ensure devices are powered off or that hot-swap procedures recommended by the equipment manufacturer are followed when installing. After physical connection, verify link status and lane configuration in the device management interface to confirm that the breakout mode is active and lanes negotiate at the required speeds.
Usage recommendations
For optimal performance, use this break-out cable with compatible MikroTik equipment such as CRS504 or CCR2216 and with ports explicitly supporting QSFP28 to SFP28 breakout. Keep cable runs within the specified 3 m length to maintain signal integrity, avoid sharp bends, and ensure proper airflow and cable management in dense rack environments.
