SFP+ Receptacle with Integrated Cage
The TE Connectivity 2246040-1 is an SFP+ Micro receptacle with an integrated cage, designed for 22-position high-speed signal interfaces. This is the standard contact count for SFP+ form factor modules, meaning it mates directly with any SFP+ transceiver or active cable assembly. The cage provides EMI shielding and includes a board guide to align the module during insertion, preventing contact damage on blind-mate installations. Termination is press-fit, which avoids the thermal stress of wave soldering on the PCB and allows for rework without desoldering.
Press-Fit Assembly and Board Layout
Press-fit termination means the compliant pins cold-form into the plated through-hole, creating a gas-tight joint without solder. This is standard for backplane and high-density I/O where reflow or wave solder would risk thermal damage to the cage or nearby components. The board guide is a molded alignment feature that steers the SFP+ module into the receptacle, reducing the risk of stubbing the 22 signal contacts.
