PL-KP2-00-000-15 The unique one-piece, pluggable, press-fit cage represents one of Picolight s complementary products to the Small Form Factor Pluggable (SFP) transceivers.

1 PL-KP The unique one-piece, pluggable, press-fit cage represents one of Picolight s complementary products to the Small Form Factor Pluggable (SFP) transceivers. Optimized for use with all transceiver products complying with the SFP multisource agreement (MS), 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. Key benefits Compatible with all MS compliant SFP transceivers and PWB layouts for single and double sided applications Robust one piece design PCI compliant and solder-down version also available RoHS Compliant and Lead-Free pplications 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, igabit Ethernet, and SONET Supports all industry SFP transceivers, using MS-compliant board layouts and hole sizes for single and double sided applications Extensive compatibility testing with industrywide MS-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 PWB, reducing field failures due to cage pull up Shorter press fit pins enable.090 PCB thickness for belly-to-belly applications R3 March 2006

2 PL-KP features RoHS Compliant and Lead-Free Proven SFP MS compliant transceiver cage Supports MS compliant board layout and hole sizes Tested for insertion force and retention PCI compatible version available Supports multiple system configurations Belly-to-belly or dual sided boards Robust manufacturing process Sturdy construction Hardened spring tempered alloy One piece metal design Cage retention strength of 27 lbs Simple assembly Utilizes common manufacturing equipment and processes Press-fit attachment before or after soldering 360 degree EMI contact fingers Low emission design FCC Class B compliant The PL-KP press-fit cage accommodates all MS-compliant SFP transceivers, and is ideally suited for application on printed wiring board (PWB) with a minimum thickness of inches for single sided application and a minimum of.090 inches for double sided applications. The excellent material memory characteristics provide high cage retention to the PWB, resulting in fewer field failures.

3 Section 1 Functional description The press Fit Cage is designed in compliance with the Small Form Factor Pluggable (SFP) Transceiver Multisource greement (MS) See Figure 1. PL-KP may be used with both the single-sided PWB layout and the double-sided PWB layout and double-sided offset PWB layout.

The double-sided PWB layout allows for one cage on the topside of the card and

belly-to-belly) (See Figure 2, Figure 3 and Figure 4).

The PWB must be a minimum of 0.090" thick for belly-to-belly applications.

4 The double-sided PWB 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, Figure 3 and Figure 4). The pins are staggered to avoid interference upon installation. The PWB must be a minimum of 0.090" thick for belly-to-belly applications. Figure 2 Belly-to-belly mounting Figure 3 Belly-to-belly mounting Figure 4 Belly-to-belly front view March 2006 Page 4 of R3

The double-sided offset PWB layout allows for cages on both sides of the

(offset belly-to-belly) (See Figure 5, Figure 6 and Figure 7).

090" thick for offset belly-to-belly applications.

5 The double-sided offset PWB layout allows for cages on both sides of the PWB, but staggered to allow more room for finger access between the units (offset belly-to-belly) (See Figure 5, Figure 6 and Figure 7). The PWB must be a minimum of 0.090" thick for offset belly-to-belly applications.

6 Section 2 Installation guide These cages are designed to be pressed into a PWB with an insertion force of about 60 lbs total (Each of the 8 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 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. press machine similar to the MEP-6T/12T manufactured by utomated Services roup, 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 PWB. It takes 27 lbs to remove a cage from a PWB. ctual insertion and removal force may vary depending on plating material and finished hole size. March 2006 Page 6 of R3
