Product Highlights
Universal QSFP+ to SFP+ Conversion
- The Mellanox MAM1Q00A-QSA (NVIDIA Dynamix QSA) is a 4-channel to single-channel pluggable adapter that enables seamless integration of 10G SFP+, 1G SFP single-channel optical modules and cables into 40G QSFP+ ports. This versatile compatibility allows you to reuse your existing SFP/SFP+ inventory with QSFP+ devices.
Cost-Effective Port Utilization
- The MAM1Q00A-QSA allows you to use low-cost, widely available 10G SFP+ transceivers in expensive QSFP+ ports, significantly reducing the cost of 10G connectivity on 40G switches and adapters.
Seamless Integration with Mellanox Ecosystem
- Officially certified by Mellanox, the adapter is pre-tested for compatibility with Mellanox switches, network adapters, and management software. It operates as a native SFP+ port, requiring no special drivers or firmware.
Full Pass-Through DDM Monitoring
- Unlike some generic adapters, the MAM1Q00A-QSA fully passes through the DDM/DOM signals from the connected SFP+ transceiver. This allows you to monitor optical power, temperature, and other parameters directly through your switch management interface.
Simple Plug-and-Play Deployment
- There's no configuration required. Just insert the adapter into a QSFP+ port, plug in your 10G SFP+ transceiver, and the link will come up automatically. This makes it ideal for quick, on-site deployments and network upgrades.
Robust and Reliable Design
- Built to Mellanox's high standards, the adapter features a durable metal housing and gold-plated contacts for excellent signal integrity. It's designed for continuous operation in demanding data center environments.
FAQ(Mellanox MAM1Q00A-QSA)
1.Is the MAM1Q00A-QSA compatible with both 1G SFP and 10G SFP+ modules?
- Yes. As a 4-channel to single-channel pluggable adapter, it supports both 1G SFP and 10G SFP+ optical modules as well as direct-attach cables for use on 40G QSFP+ ports.
2.Does this QSA adapter support DDM/DOM monitoring?
- Yes. It provides full DDM/DOM pass-through, allowing real-time monitoring of optical power, temperature, voltage and laser current of the inserted SFP/SFP+ transceiver via the switch management system.
3.Can MAM1Q00A-QSA work on third-party brand switches?
- It is originally optimized for Mellanox/NVIDIA switches and NICs; it also supports mainstream compatible brand devices with open QSFP+ port policy, no extra configuration needed.
