Data Sheet
RoHS-Compliant Small Form Factor Pluggable Press-Fit Cage
The unique lead-free and RoHS-Compliant, pluggable, press-fit cage represents one of
Lumentum complementary products to the Small Form Factor Pluggable (SFP) transceivers.
Its 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
multisource agreement (MSA), the cage design allows for low-cost implementation using
standard manufacturing processes. Its hardened spring-tempered material, plus 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 all
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 for single and double sided
applications
Key Features
• Compatible with all MSA-compliant SFP transceivers and PCB
layouts for single and double sided applications
• Enhanced EMI performance at data rates up to and above
4Gbps
• RoHS-compliant and lead-free
Applications
• Switch and hub devices
• Extensive compatibility testing with industry-wide MSA-based
modules for interoperability in multiple vendor implementation
• Mass storage systems interconnect
• Backward compatible design offers superior mechanical
stability, simplifying implementation to customer PCBs
• Enterprise switch interconnects
• Host adapter cards
• 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

(PL-KP2-00-000-06)
The double-sided PCB layout allows for one cage on the topside
of the card and one on the bottom side that is directly under the
topside cage (called belly-to-belly) (See Figure 2 and Figure 3).
The pins are staggered to avoid interference upon installation.
The PCB must be a minimum of 0.114” thick for Belly-to-Belly
Applications.
The PL-KP2-00-000-06 press-fit cage accommodates all MSAcompliant SFP transceivers, and is ideally suited for application
on printed circuit board (PCB) with a minimum thickness of
0.114 inches for belly-to-belly applications. The excellent material
memory characteristics provide high cage retention to the PCB,
resulting in fewer field failures.

Installation Guide
These cages are designed to be pressed into a PCB with an
insertion force of about 90 lbs total (Each of the 12 press fit pins
require an approximate force of 7.5 lbs/pin). 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.
Figure 3 Belly-to-belly front view
The double-sided offset PCB layout allows for cages on both
sides of the PCB, but staggered to allow more room for finger
access between the units (offset belly-to-belly) (See Figure 4 and
Figure 5). The pins are staggered to avoid intereference upon
installation. The PCB must be a minimum of 0.114” thick for
Offset Belly to Belly applications.

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. Actual
insertion and removal force may vary depending on plating
material and finished hole size. Cages should not be re-installed
once they are removed from a board.
