Dell Networking SFP28 transceiver module - SFP28

The Dell 407-BBXU supports a maximum data transfer rate of 25,000 Mbit/s (25GbE).

This transceiver is designed for Multi-Mode Fiber (MMF) and uses a Duplex LC connector.

The maximum transfer distance for the Dell 407-BBXU over multi-mode fiber is 300 meters.

Yes, the Dell 407-BBXU features hot-plug support, allowing installation or removal without powering down the network device.

DDM provides real-time access to operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage, aiding in performance monitoring and troubleshooting.

No, the Dell 407-BBXU is designed for multi-mode fiber (MMF) only and does not support single-mode fiber (SMF).

It is compatible with various Dell Networking switches (e.g., S5200 series) and Dell PowerEdge servers that feature SFP28 ports.

Ensure the module is fully seated in the SFP28 port. Verify compatibility with your specific Dell device model. Try inserting the module into a different SFP28 port.

Check that the duplex LC fiber optic cable is securely connected at both ends. Verify that the fiber cable is not damaged and is the correct type (multi-mode). Ensure the corresponding port on the remote device is active and configured correctly.

Inspect the fiber optic cable and connectors for dirt or damage. Clean the connectors if necessary. Use the Digital Diagnostic Monitoring (DDM) interface to check optical power levels (transmit and receive) and transceiver temperature for any anomalies.

Verify the integrity of the fiber optic cable. Ensure the maximum transfer distance of 300m is not exceeded. Check the DDM for signal degradation or excessive error counts.
