QSFP (Quad Small Form-factor Pluggable)

QSFP, or Quad Small Form-factor Pluggable, is a compact, hot-swappable device used in networking and telecommunications to connect high-speed data devices. It can support multiple data channels (often four) in a single module, allowing for high data transfer rates, which is essential for data centers and network switches. The QSFP design enables easy upgrades and replacements without needing to power down the entire system, making it efficient for managing network connectivity. This technology is widely used in data transmission applications like Ethernet, Fiber Channel, and InfiniBand.
