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. For example, an SFP28-based cable can be connected to Mellanox’s 100GbE ConnectX®-4 NIC and to the 32 x 100GbE SN2700 Ethernet switch. The QSA28 conforms to the SFF-8402 for the SFP28 side and to SFF-8665 for the QSFP28 standards and is thoroughly tested to meet strict quality requirements. 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 meeting the Small Form Factor Pluggable (SFP) Transceiver Multi-source Agreement (MSA).

As a growing number of homes contain more than one computer, their users must find ways to network them. The primary purpose for creating a home network tends to be to provide Internet access to all computers within the house. There are other good reasons, however. These include enabling LAN gaming, data backups from one machine to another and the sharing of music within the home.
