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 requirements 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 including 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 between the standoffs of the cage assembly
and the pc board.

3.12. EMI/Dust Plug
An EMI/Dust Plug should be installed into its respective port when the module is not mated with the cage
assembly.
3.13. Repair and Rework
Damaged or defective connector and cage assemblies must be removed and replaced.
If repair or rework to the pc board requires soldering after the connector and cage assembly has been seated
onto the pc board, the following must apply:
--- After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of
the solder and flux for recommended cleaning solvents. Cleaners must be free of dissolved flux and other
contaminants. Even when using a “no clean” solder paste, it is imperative that the contact interface be
kept clean of flux and residue (since it acts as an insulator).
DANGER
Consideration must be given to toxicity and other safety requirements recommended by the solvent manufacturer. Refer to the
manufacturer's Material Safety Data Sheet (MSDS) for characteristics and handling of cleaners. Trichloroethylene and
Methylene Chloride is not recommended because of harmful occupational and environmental effects. Both are carcinogenic
(cancer-causing).
--- Air drying is recommended. Otherwise, make sure that temperature limitations are not exceeded:
-55° to 105°C [-67° to 221°F]. Excessive temperatures may cause housing degradation.
4. QUALIFICATION
SFP+ Connectors are Recognized by Underwriters Laboratories Inc. (UL) in File No. E28476.
5. TOOLING
Tooling part numbers and instructional material packaged with the tooling are given in Figure 7.

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

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 assembly.
