Network transceiver module Dell 407-BCBN SFP+ fiber optic 10 Gbit/s 850 nm

Dell 407-BCBN is an SFP+ fiber optic transceiver module that supports up to 10 000 Mbit/s (10 Gbit/s) data rate at an 850 nm wavelength. Engineered for SFP+ slots, the module provides short-range multimode fiber connectivity for compatible Dell servers and network devices. The hot-pluggable transceiver extends network reach for uplinks, server interconnects and data center switch links while fitting Small Form Factor Pluggable (SFP+) ports and delivering 10GbE performance. It also includes an enhanced digital diagnostic monitoring interface to report operating parameters in real time.

Advantages

The SFP+ transceiver offers compact, hot-swappable installation for minimal downtime and straightforward replacement. Its 850 nm multimode design supports short-range 10 Gbit/s links commonly used within racks and between adjacent racks. Integrated digital diagnostics provide real-time visibility of temperature, laser bias current, transmitted and received optical power, and supply voltage, enabling proactive monitoring and easier troubleshooting. Compatibility with SFP+ slots ensures broad interoperability with network switches and servers that accept SFP+ modules.

Suitable for

• Short-range 10 Gbit/s uplinks between switches and aggregation devices
• Server-to-switch or server-to-server interconnects in data centers and server rooms
• High-density rack environments requiring SFP+ short-reach multimode fiber links
• Environments where real-time transceiver diagnostics are required for monitoring

How to use

Power down is not required for insertion or removal in systems that support hot-swapping; follow the host device vendor’s hot-plug instructions. Insert the transceiver into an SFP+ slot until it latches, then connect multimode fiber patch cables with compatible LC connectors. Verify link status on the host network device and configure the port settings (speed, duplex, auto-negotiation or fixed 10GbE mode) as required by your network. Use the host management or monitoring tools to read the digital diagnostic information for performance verification and troubleshooting.

Usage recommendations

Use multimode fiber rated for 10 Gbit/s at 850 nm and keep patch cable lengths within short-range limits typical for multimode links. Avoid bending the fiber beyond manufacturer bend-radius recommendations and ensure clean connector end-faces before mating. Monitor diagnostic parameters to detect degraded optical power or temperature anomalies and replace the transceiver if diagnostic readings consistently fall outside normal operating ranges.
