TE Connectivity’s SFP+ direct attach copper cable assemblies are a high speed, cost effective alternative to fiber optics in 10Gb Ethernet, 8Gb Fibre Channel and InfiniBand applications.
The SFP+ product family extends the use of the Small Form-Factor Pluggable (SFP) interconnect up to 10 Gb/s. This system meets the performance requirements of SFF (Small Form-Factor) specification SFF-8431 and supports 8G Fiber Channel and 10G Ethernet applications. The SFP+ product family includes cages, connectors, and copper cable assemblies.
The ganged (single-row) SFP+ cages are offered in two designs that address EMI containment: with EMI springs and with elastomeric gaskets. Single port cages are offered with EMI springs only. The cages come in single port, 1x2, 1x4, and 1x6 port configurations. Lightpipes are also an option for all SFP+ cage styles. 16G SFP+ cages are currently only offered with elastomeric gaskets.
The 20 position SMT connectors for single-row applications include enhanced contact constructions for lower loss at the higher data rates. The SFP+ and 16G SFP+ connectors maintain compliance with the original SFP MSA, providing a drop-in replacement. However, an alternate PCB layout can be used to reduce impedance discontinuity at the host board termination area.
