Precision’s Quad Small Form-Factor Pluggables (QSFP/QSFP+) are hot-swappable optical transceiver modules that support high-density 40G data transmission among a wide variety of routers, switches and optical transport equipment.

QSFP/QSFP+ modules support Gigabit Ethernet, Fiber Channel, Infiniband and SONET/SDH applications. The form factor also has the capability to replace up to 4 small form factor (SFP) transceivers for greater port density and cost savings.
