Axiom 40G QSFP+ SR4 Transceiver

This Axiom transceiver delivers 40GBASE-SR4 connectivity over multi-mode fibre at 850nm. It uses the QSFP+ form factor with an MPO connector and complies with QSFP+ MSA SFF-8436, IEEE 802.3ba and RoHS standards. The module is new and serialised for guaranteed OEM compatibility.

Suited for 100m OM3 or 150m OM4 links

Network engineers extending 40G links within a data centre rack or row will find the reach matches OM3 and OM4 plant. Buyers needing single-mode distance, CWDM wavelengths or a different form factor such as CFP should look at other modules.

Deciding spec: 40GBASE-SR4 over multi-mode fibre

The 40GBASE-SR4 data rate and 850nm multi-mode interface determine whether this transceiver fits the link budget and switch port. Verify the host equipment accepts QSFP+ SR4 modules before purchase.

Questions about this item

What comes in the box with the Axiom PAN-QSFP-40GBASE-SR4-AX and what must I buy separately?

The transceiver ships as a single module. You must purchase OM3 or OM4 multi-mode fibre patch cords with MPO connectors separately to complete the link.

How do I choose between the OM3 and OM4 distance ratings for this 40GBASE-SR4 module?

Use OM3 fibre for runs up to 100 metres and OM4 fibre for runs up to 150 metres; the transceiver supports both distances at 850 nm.

What does the 40GBASE-SR4 rating mean when the module is installed in a live switch?

It delivers four lanes of 10 Gbit/s each over multi-mode fibre using an MPO interface, compliant with IEEE 802.3ba and QSFP+ MSA SFF-8436.
