zSFP+ Pluggable I/O Interconnect
SFP28 Direct Attach Copper Cable Assemblies
TE’s SFP28 passive copper cable assembly features two dierential copper pairs, providing one data transmission channel at
speeds up to 28Gbps per channel that meets 25G Ethernet performance requirements. SFP28 is designed for applications in
the data center, networking and telecommunications markets that require a high speed, reliable cable assembly,
Oered in a broad range of wire gages – from 26AWG through 33AWG – this next generation copper cable assembly features
low insertion loss and low cross talk. TE’s SFP28 assemblies share the same mating interface with SFP+ form factors, making
it backward compatible with existing SFP+ I/O ports. SFP28 can be used with legacy 10G Ethernet and 16G Fibre Channel
applications with substantial signal integrity margin.
In addition to SFP28 straight cables, TE oers break out assemblies with a 100G QSFP28 module on one end breaking out
to four SFP28 modules on the opposite end of the assembly. In-line SI based production testing ensures that each cable
assembly meets the electrical performance requirements of the applicable industry standard specification.
