NVIDIA LinkX network adapter - Hopea

Mellanox DynamiX QSATM QSA28, QSFP28 to SFP28 adapter, enables a smooth cost-effective connection between a single lane transceiver/cable and a quad lane port. The QSA28 provides the possibility to connect an SFP28/SFP+/SFP transceiver or cable to a QSFP28 port of an Nx100Gbps switch or Network Interface Card (NIC).The QSA28 should be installed into a QSFP28 port, and is intended to either connect a switch QSFP28 port to a NIC SFP28 port, or connect a NIC QSFP28 port to a switch SFP28 port. The adapter has a QSFP28 form factor with a receptacle for SFP28 transceiver/AOC/DAC connector. The QSA28 provides a solution for integrating systems using different vendors' equipment, since it is vendor agnostic and provides a direct path to the SFP unit's memory. The QSA28 interoperates with all major optical module and direct attach copper cable vendors.Its design ensures minimum loss on the conversion path between the QSFP28 cage and the SFP28 receptacle. The RF (high-speed data) channel of the SFP28 receptacle is connected to lane 1 of the QSFP28 connector. The three remaining RF channels on the QSFP28 connector are not connected. DynamiX QSA28 is qualified for 10GbE SFP+ and 1GbE SFP transceivers.
