MikroTik XQ+CM0000-XS+ QSFP28 to SFP28 Converter | 100G/40G to 25G/10G/1G

MikroTik XQ+CM0000-XS+ is an economical QSFP28-to-SFP28 converter designed to allow compatible SFP, SFP+ and SFP28 modules to be used in QSFP28 ports. It provides a practical way to expand compatible MikroTik networking equipment by using existing 1G, 10G or 25G SFP-family modules in QSFP28 100G/40G ports.

The converter is particularly useful with high-speed MikroTik platforms such as the CRS504, CRS518 and CRS510, where a QSFP28 port may otherwise require a QSFP-family transceiver or cable. According to MikroTik, the XQ+CM0000-XS+ supports data rates of 1G, 10G and 25G and accepts SFP, SFP+ and SFP28 module formats.

MikroTik XQ+CM0000-XS+ Key Features

• QSFP28 to SFP-family conversion: Allows SFP/SFP+/SFP28 modules to be used in compatible QSFP28 ports.
• 1G, 10G and 25G support: Supports data rates of 1Gbps, 10Gbps and 25Gbps according to MikroTik’s specifications.
• Compatible module formats: Supports SFP, SFP+ and SFP28 modules.
• Designed for QSFP28 ports: Provides a physical conversion solution for compatible 100G/40G QSFP28 interfaces.
• Cost-effective expansion: Helps reuse existing SFP-family transceivers instead of requiring a separate QSFP module for every application.
• Compact design: Suitable for dense data-center and high-speed switching environments.
• Wide tested temperature range: Tested ambient temperature from -20°C to +85°C.
• Approx. 100,000-hour MTBF: MikroTik specifies approximately 100,000 hours at 25°C.

What Does the MikroTik XQ+CM0000-XS+ Do?

The XQ+CM0000-XS+ acts as a physical interface converter between a QSFP28 cage and an SFP-family module. The adapter is inserted into a compatible QSFP28 port, providing an SFP/SFP+/SFP28 interface for the selected transceiver.

This is useful when a network switch or router has available QSFP28 ports but the required network connection uses an SFP, SFP+ or SFP28 module. Instead of changing the entire networking architecture, the converter can allow a compatible SFP-family module to be used with the QSFP28 interface.

1G, 10G and 25G Connectivity

MikroTik specifies the XQ+CM0000-XS+ for 1G, 10G and 25G data rates. This means it can be paired with appropriate SFP, SFP+ or SFP28 modules depending on the supported mode of the host device and module.

Compatible MikroTik Networking Platforms

MikroTik lists the XQ+CM0000-XS+ among the compatible interfaces for several of its high-speed switching platforms. The official compatibility documentation includes models such as the CRS504-4XQ-IN, CRS518-16XS-2XQ-RM, CRS510-8XS-2XQ-IN and CRS520-4XS-16XQ-RM, along with other compatible devices.

This makes the converter particularly useful when deploying high-density 100G switching hardware while still needing to connect lower-speed 1G, 10G or 25G network equipment.

Ideal for Data Center and High-Speed Networks

The XQ+CM0000-XS+ can be useful in data centers, server rooms, ISP networks and high-performance network environments where different Ethernet generations need to coexist.

For example, a network may have a 100G QSFP28-capable switch at the aggregation layer while individual servers or network devices use 25G SFP28, 10G SFP+ or 1G SFP connectivity. The converter provides a way to use compatible SFP-family modules in the QSFP28 port.

XQ+CM0000-XS+ vs QSFP28 Transceiver

Important Compatibility Considerations

The XQ+CM0000-XS+ is not itself a fiber transceiver. It provides the physical interface conversion required to use a compatible SFP-family module. A suitable SFP, SFP+ or SFP28 transceiver or DAC must therefore be selected separately according to the required speed, media type and distance.

Actual operating speed also depends on the capabilities of the host QSFP28 port, the inserted module and the connected device. MikroTik maintains a detailed hardware compatibility matrix for SFP, SFP+, SFP28, QSFP+ and QSFP28 interfaces.

Frequently Asked Questions

What is MikroTik XQ+CM0000-XS+?

MikroTik XQ+CM0000-XS+ is a QSFP28-to-SFP-family converter that allows compatible SFP, SFP+ and SFP28 modules to be used in compatible QSFP28 ports.

What speeds does XQ+CM0000-XS+ support?

MikroTik specifies support for 1G, 10G and 25G data rates.

Can I use an SFP28 module with XQ+CM0000-XS+?

Yes. SFP28 is one of the supported module formats, with 25G operation subject to compatibility with the host device and connected equipment.

Can I use an SFP+ module?

Yes. The converter supports SFP+ modules for compatible 10G applications.

Can I use a 1G SFP module?

Yes. MikroTik specifies 1G support and compatibility with SFP modules.

Does XQ+CM0000-XS+ convert 100G directly to 25G?

It provides an SFP-family interface inside a compatible QSFP28 port. The actual operating rate is determined by the installed module and supported port configuration; it should not be treated as a passive 100G-to-25G breakout cable.

Is the XQ+CM0000-XS+ a transceiver?

No. It is a converter/adapter. The required SFP, SFP+ or SFP28 module is installed separately.

Which MikroTik switches support XQ+CM0000-XS+?

MikroTik’s compatibility documentation lists the converter for several QSFP28-capable platforms, including CRS504, CRS518, CRS510 and CRS520 series devices.

What is the operating temperature of XQ+CM0000-XS+?

MikroTik specifies a tested ambient temperature range of -20°C to +85°C.
