The Quad to Single Small Form Factor Pluggable adapter is the world's first solution for the QSFP to SFP+ conversion challenge. The QSA enables smooth, cost-effective, connections between Virtual Protocol Interconnect (VPI) or 40 Gigabit Ethernet adapters using contemporary QSFP ports and 1 or 10 Gigabit Ethernet networks using existing SFP or SFP+ based cabling. Similarly, Ethernet switches with 40 Gb/s QSFP ports can connect to servers with 10Gb/s Ethernet NIC ports using QSA. Mellanox QSA conforms to the SFF-8431 SFP+ and SFF-8436 QSFP connector standards and is 100 percent tested to strict quality requirements. The adapter is built in QSFP form factor with a receptacle for SFP+ cable connector.
