Axiom

Axiom JH231A-AX 40GBASE-SR4 QSFP+ SFP transceiver

SKU CH-PCBG-RNN44 MPN JH231A-AX

40 Gbps QSFP+ transceiver for multimode fibre at 850 nm reaching 150 m

  • 40 Gbps throughput over multimode fibre at 850 nm
  • Reaches 150 metres on OM3/OM4 links
  • QSFP+ MSA SFF-8436 compliant for broad switch interoperability
  • RoHS compliant and built to IEEE 802.3ba standard
  • Pre-coded for HP JH231A drop-in compatibility

40GBASE-SR4 QSFP+ Transceiver

The Axiom JH231A-AX is a QSFP+ transceiver designed for 40 GBps data transfer over multimode fibre at 850 nm wavelength. It reaches a maximum distance of 150 m and complies with QSFP+ MSA SFF-8436, RoHS and IEEE 802.3ba standards. The module is pre-coded for HP equipment and functions identically to original transceivers in OEM applications.

Suits 40G short-range links on HP gear

Network engineers upgrading or repairing HP switches and routers that require 40GBASE-SR4 connectivity will find this module a direct replacement. It is not intended for single-mode fibre runs, longer distances beyond 150 m, or platforms that do not accept QSFP+ form-factor transceivers with MSA-compliant coding.

Pre-coded for HP compatibility

The transceiver ships with an application-specific code that matches HP requirements, removing the need for manual configuration or third-party coding tools. This ensures immediate recognition by the host switch or router and allows mixed-brand deployments within the same network without additional setup.

Questions about this item

What type of multimode fibre cable and connector does the 40GBASE-SR4 QSFP+ transceiver require?

The module uses 850 nm wavelength over MMF and supports a maximum transfer distance of 150 m with standard MPO connectors.

Will this Axiom JH231A-AX module operate in a switch that only has 10 GbE SFP+ ports?

No, the QSFP+ form factor and 40 Gbps data rate require a QSFP+ port; it cannot be used in SFP+ slots.

How can I verify the transceiver is recognised and linked at 40 Gbps after installation?

Check the switch port status for a 40 Gbps link light and confirm the module shows QSFP+ MSA SFF-8436 compliance in the inventory output.
