MikroTik XQ+BC0003-XS+ 100G to 4x25G Breakout Cable

The MikroTik XQ+BC0003-XS+ is a QSFP28 to 4xSFP28 breakout cable engineered for high-density optical interconnect scenarios requiring fan-out of 100 Gigabit ports into four 25 Gigabit channels. This passive direct-attach cable eliminates the need for separate breakout modules, reducing footprint and complexity in data center switching fabrics and server connectivity architectures.

The cable delivers native support for 100G-to-4×25G port proliferation across modern switching platforms, enabling organizations to maximize existing infrastructure investment by distributing bandwidth across multiple server interfaces. Operating over distances up to 3 meters, it maintains full signal integrity for passive copper transmission without active components or external power requirements.

Designed for deployment in enterprise data centers, high-performance computing clusters, and carrier-grade network facilities, the XQ+BC0003-XS+ integrates seamlessly with MikroTik CloudRouter and RouterOS-based switching solutions while maintaining compatibility with standards-compliant QSFP28 and SFP28 optics ecosystems.

Ideal for

• Fan-out of 100G uplink ports to 4×25G server connections in hyperscale data center switch fabrics
• High-density server cluster interconnect where per-socket 25G NICs require aggregated 100G fabric access
• Network virtualization and SD-WAN hub aggregation across multiple 25G subscriber interfaces
• Storage area network (SAN) switching with parallel 25G paths to NVMe-oF and Fibre Channel endpoints
• Carrier edge aggregation where 4 customer-facing 25G handoffs require consolidated 100G core connection
• Machine learning cluster training nodes requiring balanced 25G per-GPU interconnect with single 100G fabric port
