zSFP+™ SMT 20-circuit connectors and cage assemblies provide excellent signal integrity and Electro Magnetic Interference (EMI) protection.

Molex’s zSFP+ SMT connector supports current 10 Gbps Ethernet and 16 Gbps Fibre Channel applications, with the ability to support up to 40 Gbps serial lanes. The preferential coupling design uses a narrow-edge, coupled blanked- and formed-contact geometry and insert molding to optimize electrical performance. The zSFP+ connector shares the same PCB footprint, mating interface and EMI cage dimensions as the SFP+ 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.

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 light emitting diodes (LEDs).

LC duplex cable assemblies, with optical mode 3 and 4 (OM3, OM4) fiber, are used with zSFP+ optical modules. LC duplex assemblies offer a high-performance interconnect solution with customization 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.
