TE Connectivity (TE), introduced its new quad small form factor pluggable double density (QSFP-DD) connectors, cages and cable assemblies, which address next-generation data center needs by increasing density through an existing QSFP form factor to reach speeds up to 400 Gbps. This 8 lane solution is designed for both 28G NRZ and 56G PAM-4 protocols, with a roadmap to 112G PAM-4 for future system upgrades.

Unlike other 400G solutions on the market, QSFP-DD products are backward-compatible, which can provide an easy upgrade path from existing QSFP designs. TE’s QSFP-DD products leverage proprietary zipper fin heatsink technology allowing them to work cost-effectively in 15-18W applications. 

TE offers a broad QSFP-DD portfolio which includes 1x1 through 1x6 cages and surface mount (SMT) connectors on a 0.8mm pitch, along with various lengths and wire sizes of straight and breakout passive copper cable assemblies. Customer specific designs with different lightpipes, heatsinks and cable assemblies are also available, supported by TE signal integrity experts.
