The SFP+ series stacked SFP+ Connector and Cage Assemblies to interconnect SFP+ and SFP fibre optic or copper transceiver modules to printed circuit (PC) boards. The SFP+ Connector and Cage Assembly is a pre-assembled unit available in a 2x1, 2x2, 2x4, 2x5, 2x6 or 2x8 configurations. The assembly is also available with light pipes. It features compliant pin contacts for mechanical retention to the pc board and to provide electromagnetic interference (EMI) suppression, thermal vent holes and panel ground features (panel ground springs or elastomeric gasket) to provide electrical contact to the bezel. In addition, the cage assembly has a locking latch and a kick-out spring for each mating module. An EMI/Dust Plug is used when the module is not mated to the cage assembly. It is designed to be inserted into a bezel after being seated onto the pc board. The connector consists of housing with dual 20-position receptacle ports and compliant pin contacts on 0.8 mm centreline spacing.
