Molex zSFP+ interconnect system

zSFP+ interconnect system for 56Gbps serial channels, delivering unparalleled signal integrity with superior EMI protection for next-generation Ethernet and Fibre Channel applications.

zSFP+ SMT 20-circuit connectors and cage assemblies provide excellent signal integrity and EMI protection.

zSFP+ SMT connectors support current 10Gbps Ethernet and 16Gbps Fibre Channel applications, with the ability to support up to 25Gbps serial lanes. The preferential coupling design uses a narrow-edge, coupled blanked- and formed-contact geometry and insert molding to optimise electrical performance. The zSFP+ SMT connector shares the same PCB footprint, mating interface and EMI cage dimensions as the SFP+ SMT form factor, making it backward compatible.

Single-port and 1x ganged cages are available to support multiple design options. Single-port cages feature press-fit, solder-post and PCI (1°) versions, providing a flexible solution for use with various board thicknesses and assembly processes at a comparable cost to SFP+ cages. EMI ganged cages utilising new Gen II EMI belly gaskets provide superior EMI shielding compared to SFP+ cages.

The press-fit tails accommodate belly-to-belly applications for both single and ganged cages to ensure the best use of PCB space. Cages will offer optional rear- and side-mounted lightpipe cover assemblies to allow for flexibility of PCB signal routing for LEDs.

LC duplex cable assemblies, with optical mode three and four (OM3, OM4) fiber, are used with zSFP+ optical modules. LC duplex assemblies offer a high-performance interconnect solution with customisation options for cable length and strain-relief boots including straight, 45° and 90°. LC loopback assemblies provide a stable and convenient means for testing SFP and SFF devices in many applications.

Temp-Flex 28 Gbps cable assemblies deliver next-generation data rates while delivering significant insertion loss improvements and enhanced cost efficiencies.

3M has presented New 3M™ 100G QSFP28 Direct Attach Copper Cable Assemblies, 9Q Series are passive copper cable assemblies which utilize 3M Twin Axial Cable technology to create a highly-flexible, foldable, high-performance solution.
