The unique RoHS-Compliant, one-piece, pluggable, press-t cage represents one of

Lumentum’s complementary products to the Small Form Factor Pluggable (SFP) transceivers.

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 exibility over the life of the system.

Key Features

• Compatible with all MSA compliant SFP transceivers and

PCB layouts for single and double sided applications

• Robust one piece design

• PCI compliant and solder-down version also available

• RoHS-compliant

Applications

• Switch and hub devices

• Mass storage systems interconnect

• Host adapter cards

• Enterprise switch interconnects

Highlights

• Industry’s most robust and sturdy cage design optimized for all

SFP applications, including Fibre Channel, Gigabit Ethernet, and

SONET

• Supports all industry SFP transceivers, using MSA-compliant

board layouts and hole sizes for single and double sided

applications

• Extensive compatibility testing with industry-wide MSA-based

modules for interoperability in multiple vendor implementation

• One piece design offers superior mechanical stability,

simplifying implementation to 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 eld failures due to

cage pull up

The PL-KP2-00-000-xx press-t cage accommodates all MSA-

compliant SFP transceivers, and is ideally suited for application

on printed circuit board (PCB) with a minimum thickness of

0.062 inches. The excellent material memory characteristics

provide high cage retention to the PCB, resulting in fewer eld

failures.

Section 1 Functional Description

The press Fit Cage is designed in compliance with the Small Form

Factor Pluggable (SFP) Transceiver Multisource Agreement (MSA)

See Figure 1 and Figure 2. PL-KP2-00-000-xx may be used with

both the single-sided PCB layout and the double-sided PCB

layout and double-sided offset PCB layout.

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 3, Figure 4 and

Figure 5). The pins are staggered to avoid interference upon

installation. The PCB must be a minimum of .125” thick for

Belly-to-Belly Applications.

Figure 4. Belly-to-belly mounting

Figure 5. Offset 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 nger

access between the units (offset belly-to-belly) (See Figure 6,

Figure 7 and Figure 8). The PCB must be a minimum of 0.125”

thick for Offset Belly to Belly applications.

Section 2 Installation Guide

These cages are designed to be pressed into a PCB with an

insertion force of about 60 lbs total (Each of the 8 press t 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

at across the top surface of the cage. For the PCI compliant

version, (PL-KP2-00-000-21) the metal piece should be at an

angle relative to the cage of 1°. The xture should not atten 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

ne for cage installation.

Cage removal is very easy. Simply insert a at metal bar or

similar object into the cage assembly and lift it up off the PCB. It

takes 27 lbs to remove a cage from a PCB. Actual insertion and

removal force may vary depending on plating material and

nished hole size. Cages should not be re-installed once they are

removed from a board.
