Mikrotik XQ+BC0003-XS+ InfiniBand/fibre optic cable 3 m QSFP28 4x SFP28 Black

The Mikrotik XQ+BC0003-XS+ is a 3-meter QSFP28 to 4x SFP28 break-out cable designed for high-speed networking. It enables connection of multiple 25 Gigabit devices to compatible switches and routers such as the CCR2216 and CRS504. The cable includes integrated SFP28 modules and supports breaking a 40G link into four separate 10G links, providing flexible port distribution in data centre and server-room environments.

Advantages

The cable simplifies deployment by combining a single QSFP28 interface with four SFP28 outputs, reducing the need for additional transceivers. With a 3 m length it offers reach suitable for typical rack and cabinet layouts while helping to maintain tidy cabling. The built-in SFP28 connectors ensure straightforward compatibility with 25 Gigabit endpoints and support reliable high-speed data transfer.

Suitable for

• Connecting multiple 25 Gbps servers or NICs to a QSFP28 port on CCR2216 or CRS504
• Aggregating or splitting 40G links into 4 x 10G/25G links in data centres
• Short-range connections within racks and between adjacent cabinets

Key specifications

• Connector type: QSFP28 (one end) to 4 × SFP28 (other end)
• Length: 3 m
• Supported speeds: QSFP28 100G breakout to 4 × 25G; also supports dividing 40G into 4 × 10G
• Brand/Model: MikroTik XQ+BC0003-XS+

How to use

Insert the QSFP28 end into the QSFP28 port of the switch or router (for example CCR2216 or CRS504) and plug the four SFP28 ends into the corresponding SFP28 ports on target devices. Ensure each port is powered and configured for the intended speed; check device documentation for necessary interface settings. Handle the cable by the connectors and avoid tight bends to maintain optical performance.

Recommendations

Use this cable for short-range, high-speed connections inside racks or between adjacent racks. Verify device compatibility and port speed settings before installation, and avoid excessive bending or pulling to preserve cable integrity.
