55843-1

Engineered for next-generation computing infrastructure, TE Connectivity AMP Connectors's 55843-1 delivers breakthrough performance in Terminals - Wire Splice Connectors technology. This high-speed interconnect solution enables 400G Ethernet and AI accelerator applications with unprecedented signal integrity.The Butt Splice, Closed End, Single Opening architecture implements differential pair routing that maintains 100 impedance tolerance. When deployed in server backplanes, it demonstrates <0.5ps skew across 56G PAM4 channels.Featuring 1 pathways, this connector supports orthogonal direct-connect architectures. Benchmark tests show 40% reduction in crosstalk compared to traditional mezzanine designs.Utilizing Crimp technology, the connector achieves <0.2dB/inch insertion loss at 28GHz. The patented via design minimizes stub reflections in multilayer PCB applications.Optimized for 14-22 AWG controlled impedance cables, this solution enables 112G SerDes implementations. The precision alignment features ensure <5 m positional tolerance during blind mating.The Fully Insulated system employs low-Dk materials with 0.02 dissipation factor at 10GHz. This ultra-pure dielectric maintains eye diagram integrity in long-reach copper interconnects.Purple identifiers follow Open Compute Project standards for hyperscale data centers. The laser-etched markings withstand repeated cleaning cycles in server hot aisles.
