1x1 SFP+ Cages & Connectors

1x1 SFP+ Cage and Connector Selection

A 1x1 SFP+ cage provides a single module position on the host board. The metal cage guides and retains the module and can contribute to EMI shielding at the front panel. The SFP+ host connector provides the electrical interface between the module and the PCB.

Browse single-port SFP+ cages and host connectors for switches, network interface cards, servers and other equipment. Before selecting a part, confirm whether the listing is a metal cage, a separate electrical connector, or an assembly that includes both.

Options vary by part number. Use the product specifications and current customer drawing to confirm the exact construction, dimensions and operating limits.

Press-Fit vs. Solder-Tail SFP+ Cages

Press-fit and solder-tail cages use different methods to attach the metal housing to the PCB. Choose the mounting method according to the board design and assembly process.

• Press-fit: Compliant pins are seated into specified plated-through holes. Review the finished hole dimensions, board thickness, insertion tooling and seating requirements for the exact part.
• Solder tail: The cage has solderable through-hole tails. Review the tail geometry, PCB hole pattern and the soldering process specified for the part and board assembly.

The mounting method of the metal cage is separate from that of the electrical host connector. For example, a press-fit cage may be used with a separately surface-mounted connector. Check both component drawings before releasing the PCB layout.

Heat Sink, EMI Spring and Lightpipe Selection

Select the shielding and thermal features according to the module, PCB and enclosure. A cage with EMI spring fingers must make the intended contact with the front panel; verify the panel opening, grounding path and assembly tolerances in the actual design.

If a heat sink is required, compare the installed height, module contact and available airflow. The cooling requirement depends on the module power, ambient conditions and system design. Where a lightpipe is included, verify its alignment with the PCB LEDs and front-panel openings.

1x1 SFP+ Cage Replacement and Cross-Reference

A matching 1x1 port configuration does not establish that two cages are interchangeable. For an existing board, compare the complete original part number and drawing revision with the candidate part.

Check the finished PCB hole pattern, cage mounting method, host connector position, front-panel EMI interface, heat sink clearance and any lightpipe features. Review operating temperature and material requirements before sample qualification.

For examples of press-fit and solder-tail comparisons, see the SFP+ and QSFP28 cage cross-reference . Replacement candidates should be qualified for the intended application before production use.

Frequently Asked Questions

Does a 1x1 SFP+ cage include the host connector?

Not always. Some products are metal cages only, while others include an electrical connector. Check the product type, bill of materials and drawing for the exact part.

Can a press-fit cage be used with an SMT host connector?

Yes, some designs use a press-fit metal cage with a separate surface-mounted host connector. Verify the mounting requirements and alignment of both components for the selected design.

Are all 1x1 SFP+ cages interchangeable?

No. Parts can differ in their PCB hole pattern, mounting tails, front-panel shielding, heat sink provisions, lightpipe positions and temperature range. Compare the current part-specific drawings before approving a replacement.

Does every SFP+ cage require a heat sink?

No single thermal configuration suits every design. Check the module power, operating temperature, airflow and host requirements. Select and validate thermal hardware for the complete system.

Can an SFP28 module be used in an SFP+ cage?

Mechanical fit alone does not establish SFP28 support. Check the exact cage and host connector specifications, the module interface, PCB channel and host requirements for the intended data rate.

What information should I provide when requesting a replacement?

Provide the original manufacturer and complete part number, drawing revision, PCB thickness, mounting method and available enclosure clearance. Include any heat sink, lightpipe, EMI and operating-temperature requirements.
