Frequently asked questions

• What is a QSFP28 module? A QSFP28 module is a high-density transceiver that provides 100 Gbps of data throughput by utilizing four 25 Gbps lanes in a compact Quad Small Form-Factor Pluggable package. It is commonly used for data-center uplinks and high-speed interconnects between switches and routers.
• Is the Allied Telesis QSFP28 Module hot-swappable? Yes. The module is designed for hot-swappable installation in compatible Allied Telesis devices, enabling maintenance and upgrades with minimal downtime.
• Which devices are compatible with this module? The module is designed for Allied Telesis devices that support QSFP28 transceivers. As a standard QSFP28 component, it also benefits from general interoperability with equipment and cabling that follow QSFP28 specifications, though optimal compatibility is achieved within Allied Telesis ecosystems.
• What cabling do I need? Use fiber optic cabling appropriate for your QSFP28 deployment and media type (for example, multi-mode or single-mode fiber) as required by your network design and distance goals. Always refer to your device’s guidance and the module’s documentation for exact cable recommendations.
• How can I verify the module is functioning correctly? After installation, verify link status via the device management interface, check LED indicators on the module and port, and run basic throughput or loopback tests to confirm 100G performance. If issues arise, reseat the module, verify cabling, and consult the device logs for any fault codes.
• Can I mix 100G QSFP28 modules from different vendors? While QSFP28 is an industry standard, for best results and guaranteed interoperability, use modules and transceivers that are recommended or tested with your Allied Telesis devices. Mixing components from different vendors can sometimes lead to compatibility issues or require additional configuration.
