TE Connectivity (TE) has introduced its new zSFP+ stacked belly-to-belly connectors that are designed to support data rates at both 28G NRZ and 56 Gbps PAM-4. The upright latching feature for zSFP+ stacked belly-to-belly connectors is a key capability that can accommodate four row belly-to-belly applications to enable higher faceplate density and maximise PCB space usage for hyperscale data centres and networking switch applications.

This expanded portfolio includes 2x4 and 2x12 configurations, which offer design flexibility to address different application needs. zSFP+ stacked belly-to-belly connectors are backward-compatible to previous generations by sharing the same mating interface and cage dimensions with the entire SFP/SFP+/SFP 28 portfolio, facilitating easy design-in and system upgrades.

“We see that 56-gigabit PAM-4 performance is becoming a standard in hyperscale data centres and high-end network switches and routers, and many customers are demanding PAM-4 support as well as higher faceplate density,” said Jimmy Ju, Product Manager at TE Connectivity’s data and devices business unit. “TE’s new zSFP+ stacked belly-to-belly connectors offer both features to facilitate higher data centre performance.”
