This unique lead-free and RoHS-Compliant, pluggable, press-fit cage represents one of JDSU's complementary products to the Small Form Factor Pluggable (SFP) transceivers. The patented design enables enhanced EMI performance using improved shielding between the cage and bezel. Optimized for use with all transceiver products complying with the SFP multi-source agreement (MSA), the cage design allows for low-cost implementation using standard manufacturing processes. The hardened spring-tempered material, with excellent material memory characteristics, further provide for consistent transceiver mate/de-mate performance that provides for port flexibility over the life of the system.
Highlights
* Industry's most robust and sturdy cage design optimized for SFP applications, including Fibre Channel, Gigabit Ethernet, and SONET * Enhanced EMI performance due to improved mechanical shielding * Supports all industry SFP transceivers, using MSA compliant board layouts and hole sizes. * Extensive compatibility testing with industry-wide MSA-based modules for interoperability in multiple vendor implementations * Backward compatible design offers superior mechanical stability, simplifying implementation in customer PCBs * Tested for common applications and standard industry processes to allow seamless integration into manufacturing without additional equipment or requirements * Excellent material memory characteristics provide for high cage retention to PCB, reducing field failures due to cage pull up

Section 2 Installation Guide
This cage is designed to be pressed into a PCB. The required insertion force in a typical application is about 90 lbs total (each of the 12 press fit pins require an approximate force of 7.5lbs/pin). The insertion force depends on the hole diameter and plating material so individual results will vary. For best installation, a solid piece of stainless steel or similar metal should be placed flat across the top surface of the cage. The fixture should not flatten the EMI springs at the front of the cage. Care should be taken not to twist or tilt the cage during the installation process. Excessive force will result in damage to the unit. A press machine similar to the MEP-6T/12T manufactured by Automated Services Group, West Palm Beach, FL would be fine for cage installation. Cage removal is very easy. Simply insert a flat metal bar or similar object into the cage assembly and lift it up off the PCB. It takes approximately 27 lbs to remove a cage from a PCB. The actual extraction force will vary based on the hole diameter and plating material. Note: Cages are not designed to be re-installed once they are removed from a board.
