## Summary description

MikroTik adapter 1718441 converts a QSFP28 100G port to a SFP28 25G interface, enabling compatibility between 100G QSFP28 transceivers/ports and 25G SFP28 modules. Designed for network equipment supporting these form factors, it allows flexible port mapping and upgrade paths, useful for data center, telecom or aggregation switches where mixed-speed connectivity is required.

## Long description

The MikroTik QSFP28 to SFP28 adapter model 1718441 converts a QSFP28 100G port into a SFP28 25G interface, allowing a single QSFP28 cage or port to accept SFP28 25G modules. This adapter provides physical compatibility between 100G QSFP28 transceivers/ports and 25G SFP28 modules, enabling mixed-speed connectivity on equipment that supports these form factors. It is intended for network switches, routers and transceiver cages where flexible port mapping and gradual bandwidth migration are required.
Advantages
The adapter offers a compact mechanical solution to adapt higher-density QSFP28 ports for use with lower-speed SFP28 modules without requiring immediate hardware replacement. It enables cost-effective port utilization and simplifies upgrade paths by letting operators use existing 25G optics in 100G-capable cages. The design maintains standard form-factor alignment and provides a reliable electrical and mechanical interface suitable for data center and telecom environments.
Suitable for
Adapting QSFP28 100G ports to accept SFP28 25G optical or copper modules
Data center interconnects where mixed 25G and 100G equipment must interoperate
Telecom aggregation switches and routers with QSFP28 cages
Lab testing and migration scenarios during phased bandwidth upgrades
Key specifications
Form factor conversion: QSFP28 (100G physical cage) to SFP28 (25G module)
Supported module speed: 25 Gigabit Ethernet when used with SFP28 transceivers
Compatible with standard QSFP28 cages and SFP28 transceivers mechanically
Passive adapter with no active electronic components required for basic mechanical compatibility
Suitable for use with optical and direct-attach copper SFP28 modules depending on host support
How to use
Insert the adapter into the QSFP28 cage or port following the host equipment vendor’s mechanical insertion guidelines. Once the adapter is seated, insert a compatible SFP28 transceiver or direct-attach copper module into the SFP28 end of the adapter until it latches. Verify link status and module compatibility in the switch or router management interface, and configure the port speed and interface settings as required by your network. Remove the adapter by first ejecting the SFP28 module, then extracting the adapter from the QSFP28 cage according to the device’s removal procedure.
Usage recommendations
Confirm that the network equipment firmware and hardware support use of SFP28 modules in QSFP28 cages via adapters before deployment. Use matched optical transceivers and verify cable types and lane mappings for expected performance. Avoid forcing incompatible modules and follow electrostatic discharge (ESD) precautions when handling optics and adapters.
