The cage provides the mechanical retention and EMI containment for the module, while the heat sink draws thermal energy off the top of the transceiver can. This is the port-side interconnect in a 40 GbE or 4x10 GbE data path — the cage sits at the board edge, the transceiver plugs in from the panel face, and the host board routes the high-speed differential pairs to the cage's press-fit tails. ## Press-Fit Termination and Right-Angle Mounting Termination is press-fit — the compliant pin tails are pressed into plated through-holes on the host PCB, no solder required. ## EMI Shielding and Thermal Management The cage is EMI shielded — the stamped metal shell grounds to the chassis through the panel opening, containing radiated emissions from the transceiver.","metaTitle":"TE Connectivity 2057855-1 QSFP+ Cage with Heat Sink","metaDescription":"TE Connectivity 2057855-1 QSFP+ cage with integrated heat sink, EMI shielded, press-fit termination, right-angle through-hole mount.
