How to install Cisco 10/25GBASE-LR SFP28 Module for SMF

• Identify a compatible SFP28 port and cage on your Cisco device, ensuring support for 10/25GBASE-LR operation and SMF routing. Confirm that the device firmware supports dual-rate SFP28 modules.
• Prepare the fiber plant: use a clean LC duplex SMF fiber with proper connectors and be mindful of polarity and physical routing to avoid bending or stress on the fiber.
• Power or prepare for hot-swapping: although the module is designed for hot-swappable operation, take standard ESD precautions and consider swapping during a maintenance window if possible.
• Remove the existing transceiver (if applicable): release any latching mechanism and slide the old module out carefully, taking care not to damage the cage or fiber connectors.
• Insert the Cisco 10/25GBASE-LR SFP28 Module for SMF: align the module with the port, slide it in until it seats securely with an audible click, and verify the module is recognized by the device firmware.
• Connect the SMF fiber: attach the LC duplex fiber to the module’s LC connector, ensuring proper polarity and clean, secure connections.
• Power up or resume operation: if the device was powered, monitor the link status indicators and verify that the port negotiates to the expected speed (10G or 25G) automatically.
• Verify health and performance: use the device’s management interface to check link status, perform a basic loopback or throughput test if required, and consult DDM data for power, temperature, and laser bias trends.
