QSFP and QSFP+ Interconnect Solutions


A Quad Small Form-factor Pluggable (QSFP+) solution designed for high-density applications


Molex's QSFP and QSFP+ Interconnect SolutionsMolex's Quad Small Form-factor Pluggable (QSFP+) solution is designed for high-density applications. Components of the system include the Electro Magnetic Interference (EMI) shielding cage, active optical cables (AOC), passive copper cable assembly, active copper cable assembly, optical MTP cable assembly, optical loopback, 38-circuit SMT iPass™ host connector, and stacked integrated connectors and cages.

The SFF-8436 document specifies a transceiver mechanical form factor with latching mechanism, host-board electrical-edge connector and cage. The hot-pluggable transceiver integrates 4 transmit and 4 receive channels. Molex's QSFP+ transceiver can replace up to 4 standard SFP+ transceivers. The result is greater port density and overall system cost savings over traditional SFP+ products. Molex's QSFP+ cable assemblies are designed to accommodate stacked and ganged connector configurations in extremely high-density requirements. This system will support 10 G Ethernet, Fibre Channel, InfiniBand, SAS and SONET/SDH standards with different data rate options.
