Axiom 10gbase-bx40-u SFP+ for Force10 server accessory

Axiom 10G SFP+ for Force10

The Axiom 10gbase-bx40-u SFP+ module is built for Force10 server and network equipment. It provides a 10 Gigabit Ethernet link over single-mode fibre using bidirectional optics. This transceiver suits administrators upgrading or repairing existing Force10 infrastructure. The unit is listed as new condition and was first shown by the manufacturer in 2025.

Suits Force10 10G links only

This module fits Force10 ports that accept the 10gbase-bx40-u standard at 10 Gbps. It will not work in switches or servers that require a different wavelength, distance or form factor. Buyers who need longer reach, different connector types or compatibility with other vendor platforms should look at other transceivers. The 40 km rating matches the BX40 designation in the model name.

Hot-plug SFP+ installation

The SFP+ form factor allows hot insertion into a compatible cage without powering down the chassis. Align the module, push until it clicks and connect the LC simplex fibre patch cord. The most common issue is mismatched TX/RX wavelengths between the paired modules at each end of the link. Dirty or damaged fibre end faces also cause immediate signal loss.
