MikroTik XQ+BC0003-XS+ 3m 100G QSFP28 to 4×25G SFP28 Breakout Cable

MikroTik XQ+BC0003-XS+ is a 3-meter QSFP28 to 4×SFP28 breakout cable designed for high-speed 100 Gigabit networking environments. It allows a compatible 100G QSFP28 port to be split into four independent 25G SFP28 connections, making it useful for connecting multiple 25 Gigabit servers, switches, network adapters and other high-performance devices to compatible MikroTik equipment.

The cable is specifically designed for MikroTik’s 100G networking product family and is suitable for compatible devices such as the CRS504 and CCR2216. It also supports 40G operation in a 4×10G breakout configuration, providing additional flexibility for networks that contain both 100G and 40G infrastructure.

MikroTik XQ+BC0003-XS+ Key Features

• 100G QSFP28 to 4×25G SFP28: Breaks one compatible 100G QSFP28 interface into four 25G SFP28 connections.
• 3-meter cable length: Provides practical reach for rack and server-room connectivity.
• 40G breakout support: Supports 40G to 4×10G operation on compatible equipment.
• Integrated modules: QSFP28 and SFP28 transceiver ends are integrated into the cable assembly.
• High-speed data connectivity: Supports up to 100G total aggregate data rate in 4×25G configuration.
• 30 AWG construction: Designed for high-speed direct-attach connectivity.
• PVC jacket: Suitable for indoor rack and data-center deployments.
• 35 mm minimum bend radius: Helps maintain proper cable routing in dense network racks.

100G QSFP28 to 4×25G SFP28 Breakout

The primary function of the XQ+BC0003-XS+ is to divide a compatible 100G QSFP28 interface into four 25G SFP28 links. Instead of requiring four separate optical transceivers and fiber connections, the integrated breakout cable provides a direct copper connection between the main QSFP28 port and four SFP28 interfaces.

This architecture is useful in data-center and high-performance networking environments where a 100G aggregation or switching port needs to connect several 25G devices. For example, a compatible 100G MikroTik switch can connect to four 25G server NICs using a single breakout cable.

40G to 4×10G Breakout Support

In addition to its 100G/4×25G configuration, MikroTik specifies that the XQ+BC0003-XS+ also supports splitting a 40G line into 4×10G connections. This makes the cable useful in environments where both 40G QSFP+ and 10G SFP+ connectivity are required.

Actual operation depends on the port capabilities and compatibility of the connected networking equipment. MikroTik’s wired-interface compatibility documentation lists XQ+BC0003-XS+ for supported 10G SFP+/25G SFP28 and 100G QSFP28 applications.

Ideal for MikroTik 100G Networking

The MikroTik XQ+BC0003-XS+ is designed for high-speed MikroTik platforms with compatible QSFP28 interfaces. MikroTik specifically describes it as a solution for connecting multiple 25 Gigabit devices to compatible CRS504 and CCR2216 equipment.

It is particularly useful for server racks, data-center aggregation, high-performance storage networks and network infrastructure where 25G server connections are aggregated into a 100G switch or router.

MikroTik specifies a minimum bend radius of 35 mm.

What is the cable length?

The XQ+BC0003-XS+ is 3 meters long, making it suitable for typical rack and data-center interconnects.

Important Compatibility Note

The XQ+BC0003-XS+ is a high-speed breakout cable, so compatibility should be checked at the port and device level. MikroTik maintains a wired-interface compatibility matrix covering supported MikroTik hardware and breakout cables.

For third-party 25G NICs or switches, link behavior can also depend on supported speeds, FEC configuration and hardware compatibility. The cable should therefore be tested against the exact network adapters and equipment being deployed.
