US Patent 7070446 Stacked SFP connector and cage assembly

An electrical connector assembly is shown having a stamped and formed shielded cage having a plurality of ports for receiving SFP modules. The cages have an opening extending through a lower face thereof for receiving a header connector having first and second extensions which are aligned with the first and second columnar ports in the cage. Thus, the SFP modules are pluggable into individual ports, whereby two modules are interconnected to a single header connector interconnected to a motherboard.
