conforms to the and QSFP to CX4 connector standards

Mellanox cables are available with a wide range of connector types, complying with the different protocols in the market. CX4, QSFP to CX4 solutions provide highest flexibility for network installations The Quad to Single Small Form Factor Pluggable Adapter (QSFP to SFP+ adapter or QSA) is the world’s first solution for the QSFP to CX4 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 QSFP to CX4 based cabling. Similarly, Ethernet switches with 40Gb/s QSFP ports can connect to servers with 10Gb/s Ethernet NIC ports using QSA.


Mellanox QSA conforms to the and QSFP to CX4 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.QSFP+ to Cx4 have an QSFP+ connector and a Cx4/4x infiniband connector at the two sides of the cablerespectively. The Quad Small Form-Factor Pluggable Plus (QSFP+) interface provides a low-profile, high-bandwidth, low power-consumption interconnect solution for HPC computer network and large data centers. They are commonly used for DDR/ SDR infiniband applications.
