Axiom 407-BBZL-AX QSFP28 to SFP28 adapter 100 Gbps MMF

SKU CH-F7BR-FH2YG MPN 407-BBZL-AX

Connects QSFP28 ports to SFP28 modules at 100 Gbps over multimode fibre

  • Enables 100 Gbps links over multimode fibre
  • QSFP28 form factor fits high-density switch ports
  • Converts QSFP28 to SFP28 for flexible deployments
  • Model 407-BBZL-AX ensures Axiom quality and compatibility
  • Wired connectivity delivers reliable data centre performance

Adapter purpose

The Axiom 407-BBZL-AX is a QSFP28 to SFP28 adapter built for 100 Gbps multimode fibre links. It lets engineers connect a single 100G QSFP28 port to an SFP28 transceiver while keeping the cabling on multimode fibre.

Target users

This suits network teams who already run QSFP28 100G uplinks and need to patch into SFP28 equipment without changing the switch fabric. It is not for buyers who need a native 100G SFP28 module or who require single-mode fibre reach.

Deciding spec

The adapter carries a 100 Gbps data rate across a QSFP28 interface on multimode fibre. If your link must run at that speed over MMF with a QSFP28 form factor, this part fits; otherwise a different transceiver is required.

Highlights

  • Enables 100 Gbps links over multimode fibre
  • QSFP28 form factor fits high-density switch ports
  • Converts QSFP28 to SFP28 for flexible deployments
  • Model 407-BBZL-AX ensures Axiom quality and compatibility
  • Wired connectivity delivers reliable data centre performance

Questions about this item

Which form factor should I select between the QSFP28 and SFP28 ends of this adapter?

The adapter has a fixed QSFP28 plug on one side and an SFP28 cage on the other; you do not choose between them — you insert the QSFP28 end into a 100 Gbps port and plug an SFP28 module into the cage.

What does the 100 Gbps rating mean when the adapter is installed in a live switch?

It indicates the maximum aggregate throughput the QSFP28 interface can carry; the SFP28 module you insert will determine the actual link speed, up to 28 Gbps per lane.

Which interface standard governs the QSFP28 side and what throughput does it cap at?

The QSFP28 interface is built for 100 Gbps aggregate bandwidth across four lanes, while the SFP28 cage supports a single 28 Gbps lane.
