PCIe x1, x4, x16, M.2 KeyM / A+E, mPCIe (mini PCIe), U.2 (SFF-8639) PCIe extender x16 gen3 ribbon riser card cable twin axial high bandwidh flexible 8Gpbs 164pin adapter jumper

First Impression

R5y series is M.2 Key A+E Edge Connector Extension Adapter cable, adapted to PCIe x1, x4, x16, M.2 Key M / A E, mPCIe (mini PCIe), U.2 (SFF-8639) connectors to re-locate a PCIe card slot or bridge between slots on two different PCBs.

The ribbonized format of the axial cable provides a dense and flexible solution without signal attenuation for high speed PCIe Gen3 8Gbps Data Transaction, bidirectional 256Gbps (256GT/sec) for PCI x16, and 16Gpbs (16GT/sec) per PCIe lane.
