SFP+ PLUGGABLE I/O INTERCONNECTS Quick Reference Guide TE Connectivity’s (TE) family of SFP+ interconnects are designed to transfer data at speeds of up to 16 Gb/s. The portfolio features 20-position SMT connectors as well as cages in multiple configurations, and with elastomeric gasket or enhanced EMI springs to address EMI containment at higher data rates. The SFP+ interconnect family also includes thermal- and EMI-enhanced stacked configurations to further improve performance. Complementary SFP+ direct-attach copper cable assemblies are also offered by TE as a high-speed, cost-effective alternative to fiber optic cables. These assemblies enable hardware OEMs and data center operators to achieve high port density and configurability at low costs and with reduced power requirements. FEATURES AND BENEFITS Interconnect Direct-Attach Copper Cable Assemblies • Supports applications up to 16 Gb/s • Complies to SFF-8431 specifications • Cages available in single-port, ganged and stacked configurations. Belly-to-belly mounting cages also offered. • Supports up to 10 Gb/s serial data rates • Uses enhanced 20-position connector that is backward-compatible with SFP connectors • Consumes low power • Features elastomeric gaskets and springs for EMI containment • Features a pull-to-release retractable pin latch • Serves as a low-cost alternative to fiber optic cables • Offers enhanced EMI suppression • Offers heat sink and light pipe options te.com/products/sfpplus DATA AND DEVICES /// SFP+ PLUGGABLE I/O INTERCONNECTS SFP+ Pluggable I/O Interconnects Product Applications Applications by Protocol • Storage, servers, routers, switches and hubs • Network Interface Cards (NICs) • Other telecommunications equipment • 10 Gigabit Ethernet (IEEE802.3ae) • Fibre Channel: 2G, 4G, 8G and 16G • Fibre Channel over Ethernet (FCoE) SFP+ Thermal and EMI Enhancements Gasket retention plate Conductive elastomeric gasket Thermal Enhancements SFP+ stacked cages have been modified to enhance thermal performance. These changes include revised side walls of the cage for airflow through the middle of the cage to promote cooling of lower ports Additionally, two thermal vent holes have been added to each port to further enhance thermal performance. Two thermal vent holes Side walls modified to promote more air flow Latch plate EMI Enhancements SFP+ stacked cages with EMI enhancements feature a gasket retention plate with multiple attachment points that improve the electrical connection to the cage. A new right-angle design of the gasket retention plate also improves the strength of the product. A pocket spring has been added to the latch plate area to further reduce EMI emission. This component is internal to the cage assembly. The additional component still allows airflow through the front of the cage assembly.

What are the PCB termination options? • Belly-to-belly mounting allows a customer to install connectors and cages on both sides of a PCB. This design reduces board space and is an alternative solution to stacked connectors. • Cages are offered in press-fit and solder PCB termination styles. If I am currently using SFP cabling, can I use SFP+ host board configurations? • Yes. SFP+ configurations support higher rates. You can design SFP+ products in the host board for future upgrades. What data rate does SFP support? • SFP supports up to 16Gb/s. DATA AND DEVICES /// SFP+ PLUGGABLE I/O INTERCONNECTS Is TE’s footprint compatible with other suppliers? • It depends. The single port cages are designed to industry standards. The ganged versions are not compatible with all other sources. Are heat sinks available? • Yes. Riding heat sink technology is available for thermal management. Is application tooling required? • Single port assemblies do not require application tooling, yet ganged assemblies do require application tooling.
