  • 100 percent tested to strict quality requirements
  • QSFP+ form factor accepts standard SFP+ cable connectors

Adapter Purpose

The Mellanox MAM1Q00A-QSA is a QSFP+ to SFP+ adapter module that converts a 40 Gb/s port for use with 10 Gb/s SFP+ cabling. It targets network engineers and data-centre operators who need to connect 10 GbE SFP+ links into 40 GbE QSFP+ switch or adapter ports without replacing existing transceivers.

Upgrade Context

This module replaces direct 40 GbE QSFP+ interconnects when the remote endpoint only supports 10 GbE SFP+. The jump is worth it when consolidating 10 GbE links onto higher-density 40 GbE ports or when extending the life of installed SFP+ copper or fibre cables in a 40 GbE environment.

Installation Notes

Installation is a simple hot-plug of the QSFP+ end into the host port followed by insertion of an SFP+ transceiver or cable into the module receptacle. Compatibility issues usually arise when the host port firmware does not recognise the adapter or when the inserted SFP+ module exceeds the host's supported media types. The adapter conforms to SFF-8431 and SFF-8436 standards.

Questions about this item

Will this QSFP+ adapter fit a standard SFF-8436 cage?

Yes, it conforms to the SFF-8436 QSFP+ connector standard and is built in the QSFP+ form factor.

How is the adapter installed, and what step is often missed?

Insert the QSFP+ end into the 40Gb/s port, then plug the SFP+ module into the adapter receptacle; the step people miss is fully seating both connectors until the latches click.

Will the SFP+ transceiver or cable need replacement later?

The adapter itself is passive and requires no replacement; only the SFP+ transceiver or cable inserted into it may need swapping if link requirements change.
