zSFP+ (SFP28) Overview

zSFP+ (SFP28) 25 Gbps Pluggable I/O Interconnect
zSFP+ 25 Gbps Pluggable I/O Interconnect

The zSFP+ (SFP28) pluggable I/O interconnect was designed to quickly and easily upgrade SFP/SFP+ connectors from current 10-16 Gbps speeds to future 28 Gbps speeds. The product is backwards-compatible to SFP+ products-in footprint, mating interface and cage dimensions- to allow for easy drop-in replacement within current communication systems.

For newer equipment designs, the zSFP+ (SFP28) interconnect can support either 10 Gbps Ethernet or 16 Fibre Channel Gbps data rates-while accommodating a long-term upgrade path for 28- or potentially 40- Gbps performance. This equates to long-term cost savings as the product eliminates the need to fully redesign or reinstall communication equipment for higher performance.

The zSFP+ (SFP28) interconnect is compliant to SFF-8402 and has been adopted for Fibre Channel 32G (28.05 Gbps line rate). The entire product family is offered as a dual source option with Molex Incorporated.
