MikroTik XQ+CM0000-XS+ Module – SFP+ & SFP28 for SMB & Enterprise Networks

MikroTik XQ+CM0000-XS+ is a cost-effective QSFP28 to SFP28 converter designed for using SFP28 25G, SFP+ 10G, and SFP 1G modules in the QSFP28 100G/40G ports of MikroTik switches. It is deployed by network administrators and integrators looking to utilize existing SFP/SFP+/SFP28 modules in the QSFP28 ports of CRS504, CRS518, and CRS510 equipment, avoiding the purchase of dedicated QSFP28 modules where 25G, 10G, or 1G speeds are sufficient. The most cost-effective and energy-efficient solution for flexible expansion of 100G configurations without additional module costs.

The converter allows any SFP, SFP+, or SFP28 module to be inserted into the switch's QSFP28 port, operating at data rates of 1G, 10G, or 25G depending on the module used. This enables connecting equipment with SFP+ 10G or SFP28 25G ports directly to switches with QSFP28 ports without intermediate switches or costly conversion equipment. The operating range from -20°C to +85°C covers the conditions of most server rooms and enterprise racks, and an MTBF of approximately 100,000 hours at 25°C confirms reliability for continuous use.

Combining the XQ+CM0000-XS+ with existing SFP/SFP+/SFP28 modules from inventory — instead of purchasing new QSFP28 modules for each port — significantly reduces the cost per connection in infrastructures where QSFP28 100G ports are not needed at full capacity. Compatibility with CRS504, CRS518, and CRS510 confirms direct integration into MikroTik's flagship 100G switches without additional configuration.

Recommended for administrators expanding CRS504, CRS518, or CRS510 configurations who want to use existing SFP/SFP+/SFP28 modules in available QSFP28 ports, infrastructures transitioning from 10G/25G to 100G where QSFP28 ports are available but not all connections require 100G, and any deployment where optimizing connection cost by reusing existing modules is a higher priority than purchasing new QSFP28 modules for each port.
