Molex: enhanced Small Form-factor Pluggable Plus connector for 25 Gbps

The Molex enhanced zSFP+ (Small Form-factor Pluggable Plus) SMT 20-circuit connector is designed for 25 Gbps serial channels in high-speed Ethernet and Fibre Channel. The new zSFP+ interconnect assemblies are scalable for next-generation applications and provide optimal electromagnetic interference and signal integrity margins in 10 and 16 Gbps channels. Backward compatible zSFP+ connectors share the same mating interface and EMI cage dimensions as the SFP+ form factor. The zSFP+ connectors feature a preferential coupling design using insert moulding and a narrow edge-coupled blanked and formed contact geometry for optimised signal, mechanical and electrical performance while greatly reducing resonance compared to current SFP+ products. Components of the new zSFP+ interconnect system include: zSFP+ SMT 20-circuit connectors, stacked integrated connectors and passive optical cable assemblies.

The zSFP+ SMT 20-circuit connector features the same PCB footprint, mating interface and EMI cage dimensions for total backward compatibility as a drop-in replacement for current SFP+ form factor host board designs. The high-temperature thermoplastic housing can withstand lead-free processing. Single-port and 1x ganged cages support multiple port count applications and options for use with various board thicknesses and assembly processes to accommodate server and switch applications at a cost comparable to SFP+ cages. Ganged cages are available with two, four or six ports for multiple design options. The stacked integrated connector and cage is available in a press-fit application that eliminates reflow assembly and offers a compact, space saving design with ease-of-processing. An internal vertical shield provides unparalleled EMI reduction performance. Press-fit tails accommodate belly-to-belly applications for single and ganged cages to maximize use of PCB space. Optional rear and side-mounted light pipe cover assemblies allow flexibility of PCB signal routing of LEDs to provide port status and activity feedback to the user.

Molex fibre optic LC duplex cable assemblies with OM3/OM4 fibre are used with zSFP+ optical modules, offering a high-performance interconnect solution with customization options for length and strain relief boots which include straight, 45 and 90 degrees angles. LC duplex jumpers with OM3/OM4 fibre offer the enhanced launch bandwidth needed for this next generation of zSFP+ devices. Molex LC duplex connectors meet the EIA-TIA and FOCIS 10 standards and are compliant with MSA devices.
