40G Transceivers | QSFP+ Modules

CablesAndKits offers a wide variety of 40G transceivers/QSFP+ modules for your connectivity needs! Sometimes called 40G QSFP, these high-density, low-power modules are hot-pluggable and come with our lifetime warranty. QSFP modules – or Quad Small Form-Factor Pluggable modules – are a key piece of equipment for high-performance computing networks and modern data centers, allowing for powerful data transmission. These transceivers support Ethernet, fiber optics, and InfiniBand. QSFP+ has largely replaced standard QSFP modules in modern data centers due to increased data speeds, allowing for 40G connections in the same small size.
