SPF Portfolio of Interconnects

Small Form Delivers Big Performance

Our broad portfolio of small form-factor pluggable (SFP) I/O interconnects was developed to offer flexible, cost effective solutions to meet your design requirements. Each of the products in our SFP portfolio of I/O interconnects is designed to transfer data at speeds of up to 28 gigabits per second (Gbps) NRZ and 56 Gbps PAM-4. Choose from zSFP+, SFP+, Micro SFP+ and SFP, depending on your PCB space constraints. Each features surface mount technology (SMT) connectors and cages in multiple configurations. For overall energy efficiency, many of these products have been designed to offer enhanced EMI or thermal performance. The design of the SFP portfolio of products helps dissipate heat, helping to reduce system temperature and improve system performance, while requiring less power to operate the overall system.

Key Features and Benefits

Performance and Flexibility
  • Support applications up to 28 Gbps NRZ and 56 Gbps PAM-4
  • Offers cages in single-port, ganged (1xN) and stacked (2xN) configurations; belly-to-belly mounting cages also offered
  • Features elastomeric gaskets or springs for EMI containment
  • Offers heat sink and light pipe options
  • Stacked cages include an integrated high-speed connector
  • Comply to the SFF-8431 specifications
  • Complementary to the SFP portfolio of direct-attach copper cable assemblies and LC optical connectors and cable assemblies
  • Cages are available for PCI card applications (one-degree mounting angle)

Signal Quality

To enhance signal quality, the SFP portfolio focuses on the latch-plate area to reduce EMI and avoid degradation of circuit performance and ensure compliance to standards. Products are offered in both an EMI spring and EMI elastomeric gasket versions to meet customer system requirements.

Frequently Asked Questions

Q: Is the footprint for TE’s SFP products compatible with other suppliers' products?

A: It depends. In general, all single port SFP cages are designed to an industry standard. The ganged SFP versions are not compatible with all other sources. TE and Molex are providing drop-in replacement zSFP+ products to the market, but other SFP28 solutions may not be compatible. Please check with the local TE representative for the answer on your exact part or application.


Q: Are the SFP, SFP+ and zSFP+ products backward compatible?
A: Yes, in most cases the connector and cable assembly are all backward compatible – an SFP+ connector is a direct replacement for a SFP connector to ensure simple upgrade to customer systems. As these are standard products, the cable assembly will also be compatible between the systems – an SFP copper cable assembly can be inserted to a SFP+ cage and mate with a SFP+ connector on the board.
