## Long description

Dell SFP28 transceiver 407-BCHI-RFB is a 25GbE short-range (SR) optical module operating at 850 nm, intended for use in switches and servers with SFP28 ports. This compact, hot-pluggable module enables 25 Gigabit Ethernet links over multimode fiber (MMF) for data center interconnects, top-of-rack deployments and aggregation layers while preserving port density and simplifying incremental upgrades.
Advantages
The Dell 407-BCHI-RFB SFP28 module delivers a standardized 25GbE interface with low-power operation and compatibility with standard SFP28 cages. Its 850 nm VCSEL-based transceiver design supports short-range multimode fiber runs, offering a balance of performance and cost for intra-rack and adjacent-rack connections. The hot-pluggable form factor and vendor-certified MPN streamline installation, inventory management and lifecycle tracking in managed environments.
Suitable for
Short-range 25 Gigabit Ethernet links over multimode fiber in data centers
Top-of-rack (ToR) switch connections and server uplinks
Aggregation switches and spine-leaf fabric segments with SFP28 ports
Rack-to-rack interconnects within the same equipment room
Key specifications
Form factor: SFP28
Data rate: 25 Gigabit Ethernet
Wavelength: 850 nm
Reach: short-range over multimode fiber (SR)
Compatibility: designed for Dell equipment; MPN 407-BCHI-RFB
Connector: LC duplex (standard for SR optical modules)
How to use
Insert the SFP28 module into an appropriate SFP28 port on a compatible switch or server while the host device is powered or following the device vendor’s hot-swap guidance. Connect multimode fiber with LC duplex connectors to the transceiver’s optical interface, observing correct transmit/receive orientation. Verify link status and data rate through the host device management interface or CLI. Use compatible fiber (typically OM3/OM4) and appropriate patch cords to achieve the specified short-range performance.
Usage recommendations
For optimal performance, use factory-tested multimode fiber (OM3 or OM4) and quality LC duplex patch cords. Confirm firmware and hardware compatibility with the host device by checking vendor documentation using MPN 407-BCHI-RFB. Limit bend radius on fiber runs, maintain clean connector endfaces, and verify link diagnostics after installation to ensure expected 25GbE throughput.
