Axiom

Axiom QSFP+ 40GBASE-SR4 Switch Module

SKU CH-VR7G-5A9RH

Connects 40 Gigabit Ethernet links over multi-mode fibre with an MPO interface in MSA-compliant switches

  • 40 Gb/s throughput for high-density data networking
  • MPO interface connects directly to multi-mode fibre infrastructure
  • MSA compliant for drop-in compatibility across OEM platforms
  • Pre-coded application-specific firmware ensures immediate router and switch recognition
  • RoHS certified and 3.52 oz lightweight for environmentally responsible deployment

Data-centre transceiver

The Axiom QSFP+ module delivers 40 Gigabit Ethernet over multi-mode fibre for high-density switching fabrics. It targets network engineers upgrading leaf-spine links or populating new 40G ports in MSA-compliant chassis. Buyers who need single-mode reach or 100G line rates must select a different module.

40GBASE-SR4 over MPO

The decisive specification is the 40GBASE-SR4 interface with a single MPO connector, which dictates the patch-cord polarity and maximum link distance on OM3 or OM4 fibre. If the switch port expects a different wavelength or connector type, the link will not come up.

Hot-plug MSA installation

The transceiver slides into any QSFP+ cage that follows the multi-sourcing agreement and locks with the standard bail latch. The 2.9 inch depth clears adjacent ports in dense line cards. The most common error is inserting an MPO cable with incorrect polarity, which leaves the link dark despite a healthy module.

Questions about this item

What does the 40GBASE-SR4 rating mean for real-world link distance?

The module supports 40 Gigabit Ethernet over multi-mode fibre using an MPO connector, with reach determined by the fibre grade installed in your links.

How does the MSA-compliant QSFP+ interface affect deployment?

The MSA-compliant QSFP+ form factor fits any switch or router slot that follows the multi-sourcing agreement, so the module works across mixed-vendor environments.

Will the module fit in a standard switch slot given its size?

At .5 inches high, .7 inches wide and 2.9 inches deep, the module matches the standard QSFP+ footprint and mounts directly in any compliant cage.
