EMI Cage Packages Small Transceivers August 08, 2005
The Dual Port SFP EMI Cage is designed for use with both copper and optical small form-factor pluggable (SFP) transceivers in Fibre Channel, Gigabit Ethernet and Infiniband applications. It is a two-piece hybrid design that incorporates a die-cast body with the required spring features of a stamped piece. The die-cast body is solid and robust to ensure the structural integrity of its walls and top while providing the port-to-port spacing specified in the SFP specifications. The bottom, locking tabs, spring tabs and press-fit pins are all part of a single stamped piece to reduce inventory and assembly expenses. Press-fit pins allow the cage to be mounted securely to a printed circuit board without solder. But the cage is solderable if required by the application. Lightpipes can be added to the cage to display LED indicators from the host board to the chassis bezel. Pricing (no lightpipes) is under $3.25 each/10,000.
