Pulse Introduces XFP Connector Modules for High-Speed 10Gigabit Ethernet.

Innovative features enhance EMI performance

SAN DIEGO -- Pulse([?]), a Technitrol Company (NYSE: TNL), a leader in electronic component and subassembly design and manufacturing, announces a new line of 10-gigabit (10Gb) small-form-factor pluggable (XFP) modules for use with 10Gb hot pluggable optical transceiver modules. The cage and connector comply with the Multisource Agreement 3.0 (MSA 3.0) standard and support OC192/STM-64, 10Gb Fibre Channel, G.709, and 10Gb Ethernet protocols in applications such as blade servers, routers, add-drop multiplexers, and in remote base stations and central office (CO) equipment. They supply enhanced electromagnetic interference (EMI) protection for 10Gb Ethernet applications.

PulseeIUs XFP001/2/3-L series cages support three different heat sink profiles. PulseeIUs in-house tooling workshop can customize the heat sink profile, allowing designers to configure their printed circuit board (PCB) architecture to maximize the heat dissipation of the heat sink when the air flow over the heat sink is restricted due to the location of the cage and connector within the application.

The standard 1x1 cage measures 21.7mm wide x 65.3mm deep x 13.2mm high. It comes with a clip and heat sink. Heat sinks come in three interchangeable height profiles. The XFP001-L is 13.5mm, the XFP002-L is 6.5mm, and the XFP003-L is 4.2mm. The easily installed external clip attaches to the top of the heat sink and the cage, holding it in place and maintaining a solid mechanical contact between the optical transceiver and heat sink, thus assuring minimal thermal resistance and maximum heat dissipation properties without degrading EMI performance. The cage, made of nickel-plated copper alloy to prevent oxidation, is uniquely constructed so as not to deform during press fitting.

The XFP001/2/3-L has an insulating barrier underneath the main body of the cage to prevent PCB signal traces from shorting to the underside of the cage. To enhance EMI performance, a conductive gasket is located at the back of the cage to improve the electrical conductivity between the cage and the optical transceiver. A series of EMI ground contact points are placed around the opening of the cage to prevent noise escaping through the front aspect of the cage gap between the optical transceiver and the cage wall. To further enhance the screening around the connectors, a series of flexible metal contacts are used to ground the cage to the PCB, thus surrounding the connector with an effective Faraday cage to provide maximum EMI protection. A gasket is placed between the rear surface of the cage and the PCB to further seal the cage and PCB together.

The XFP001/2/3-L series is versatile and can handle optical transceiver links as well as transceivers configured to operate as traditional copper RJ45 connectors, so the series can be configured to each companyeIUs internal networking requirements for balancing load and bandwidth. PulseeIUs cage/connector package affords reliable mating of all parts, maximizing alignment with the transceiver that plugs into the cage. The package has been tested to 750 cycles minimum. The connectoreIUs surface mount pins support 0.004 inch co-planarity between pins. Contacts are selectively plated to 30 micron gold. The system is RoHS compliant.

The price for the XFP001/2/3-L cage, clip, and heat sink unit is $25.00, $26.00, or $27.00, depending on order configuration and shipping destination, for quantities of 1000 and are available for delivery in 6 weeks. The price for the XFP connector E81N0-YCUDF4-L is $5.00. This connector is compatible with all cages. The cage, clip, and heat sink can be purchased assembled with the connector, providing a tested system that is board-ready and can be connected to the transceiver.
