Description
Infineon is offering its Cage for Small Form Factor Pluggable (SFP) transceivers with the
most rigid mechanical design available on the market. The Cage is designed for press
fit applications in order to reduce high volume manufacturing effort. Press fit pins can be
also soldered if required. Externally bent bezel contact springs and one-piece
construction enhance EMI performance. As part of Infineon's Total Transceiver Solution,
the SFP Cage is your logical choice for next generation pluggable transceivers.

Application Notes
For single-sided mounting, optimum host board thickness is .059 to .062 in
[1.5 to 1.57 mm]. SFP Cage mounting holes should be plated with HASL, gold, or
immersion silver finish per MSA dimensional recommendations
For double-sided mounting, host board thickness is .118 in [3.0 mm] minimum per the
MSA. For belly-to-belly applications, one of the rear mounting feet is removed to avoid
interference (V23818-S5-N1-BB)
Installation of the SFP Cage may be done by hand or with a solid metal block across
the top surface of the Cage. Block dimensions to be controlled by customer
Removal of the Cage should be done with an internal solid metal block. Due to the
collapsing nature of the teardrop foot design, the Infineon SFP Cage is intended for
one-time installation
The Infineon SFP Cage does not cause any damage when carefully removed; the
outside profile of the teardrop feet is smooth and will not destroy pre-plated host board
mounting holes
Trapped fluids from washing process must be dried to prevent corrosion beneath SFP
Cage
Cage retention depends on finished hole size and plating thickness
System Configurations
Single-sided mounting with .640 in [16.25 mm] pitch
Double-sided "belly to belly" mounting with .640 in [16.25 mm] pitch
Double-sided "offset belly to belly" mounting with .975 in [24.77 mm] pitch
