All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters. Unless otherwise specified, dimensions have a tolerance of ±0.13 mm and angles have a tolerance of ±2°. Figures and illustrations are for identification only and are not drawn to scale. 1. INTRODUCTION This specification covers the requirements for application of Stacked SFP+ Connector and Cage Assemblies to interconnect SFP+ and SFP fiber optic or copper transceiver modules to printed circuit (pc) boards. The SFP+ Connector and Cage Assembly is a pre-assembled unit available in a 2x1, 2x2, 2x4, 2x5, 2x6, or 2x8 configurations. SFP+ Connector and Cage Assemblies are also available with light pipes. The cage assembly features compliant pin contacts for mechanical retention to the pc board and to provide electromagnetic interference (EMI) suppression, thermal vent holes, and panel ground features (panel ground springs or elastomeric gasket) to provide electrical contact to the bezel. In addition, the cage assembly has a locking latch and a kick-out spring for each mating module. The locking latch holds the module in place, and the kick-out spring releases the module for removal. An EMI/Dust Plug (for each port) is used when the module is not mated to the cage assembly to prevent contaminants from entering the chassis and assist with EMI containment. The SFP+ Connector and Cage Assembly is designed to be inserted into a bezel after being seated onto the pc board. The connector consists of a housing with dual 20-position receptacle ports and compliant pin contacts on 0.8 mm centerline spacing. The housing features alignment posts that provide stability for placement on the pc board. Each receptacle port has a card entry slot that accepts a 1.0±0.1 mm thick integrated circuit card housed in the mating module. When corresponding with personnel, use the terminology provided in this specification to facilitate inquiries for information. Basic terms and features of this product are provided in Figure 1.

3.7. Transceiver Modules CAUTION The mating transceiver module packing size cannot exceed the width of each cage port opening. This includes the part of the transceiver that is extending outside the cage. Since the port-to-port spacing has a 14.25 mm centerline, the widest transceiver width extending outside of the cage should be less than 14 mm. This will prevent any possible interference when transceivers are inserted in adjacent ports. 3.8. Bezel CAUTION It is strongly recommended that this bezel configuration NOT be used in PCI applications. The following requir ements were intended to be used in the communications industry only. A. Thickness The bezel thickness range shall be 0.8 through 2.6 mm. B. Cutout The bezel must provide a cutout that allows proper mounting of the connector and cage assembly. The cage assembly panel grounding feature must be compressed by the bezel in order to provide an electrical ground between the connector and cage assembly and bezel for EMI suppression. Care must be used to avoid interference between adjacent connector and cage assemblies and other components. The minimum allowable distance between connector and cage assemblies must be considered to ensure proper assembly. Dimensions for bezel cutout and minimum allowable distance between cutouts are shown in Figure 4.

3.9. PC Board and Bezel Position The bezel and pc board must be positioned in relation to each other to avoid interference with the function of the cage assembly module locking latch and to ensure proper function of the panel ground springs. This relationship must conform to the dimensions stated in Figure 4. 3.10. Placement The following requirements also apply to connectors and cage assemblies used for rework purposes. CAUTION To avoid damage to elastomeric gasket, panel ground springs, and compliant tails, handle only by cage sides. A. Registration The compliant pin contacts and mounting posts must be aligned with matching holes in the pc board, then inserted into the pc board simultaneously to prevent twisting or bending of the compliant pin contacts. B. Seating Using proper seating force and seating height is essential to interconnection performance. The force used to seat the connector and cage assembly must be applied evenly to prevent deformation or other damage to the compliant pin contacts. The force required to seat the connector and cage assembly onto the pc board can be calculated by: Amount of Compliant Pin Contacts 44.5 N [10 lbs] (Force per Compliant Pin Contact) = Seating Force CAUTION Over-driving of the connector and cage assembly will deform parts critical to the quality of the connection. Maximum force occurs prior to the connector and cage assembly bottoming on the pc board. The shut height of the application tool must be specifically set for proper seating of the connector and cage assembly. The shut height can be calculated by: Seating Height (Connector and Cage Assembly Seated) + Height of Seating Tool + Combined Thicknesses of PC Board and PC Board Support Fixture = Shut Height (Ram Down) The seating height, measured from the top of the cage assembly (not includi ng the panel grounding feature) to the top of the pc board, is given in Figure 5. The connector and cage assembly must be seated on the pc board not exceeding the dimensions shown in Figure 5. NOTE The shut height may need to be adjusted to obtain the 0.10 mm maximum gap be tween the standoffs of the cage assembly and the pc board. Figure 5 Cage Assembly

5.1. Seating Tool Kits The seating tool kits (each consists of a seating tool and wall support) are used to seat the connector and cage assembly onto the pc board. The seating tool and wall support are also available separately. 5.2. Extraction Tool The extraction tool is used to remove the connector and cage assembly from the pc board by pushing the pc board off of the connector and cage assembly. The part should not be reused. 5.3. Application Tool Power for the seating tools and extraction tools must be provided by an application tool (with a ram) capable of supplying a downward force of 44.5 N [10 lbs] per contact. For available application tools, call Product Information at the number at the bottom of page 1. 5.4. PC Board Support Fixture A pc board support must be used with the seating tool and the extraction tool. The support fixture provides proper support for the pc board and protects the pc board and the connector and cage assembly from damage. The support fixture must be customer designed. It is recommended that the support fixture be at least 25.4 mm longer and wider than the pc board and have flat surfaces with holes or a channel large enough and deep enough to receive any protruding components of the connector and cage assem bly.
