HPE InfiniBand NDR Cables
These cables are qualified as InfiniBand and Ethernet enabled.
InfiniBand NDR Direct Attach Copper cables (DAC) and InfiniBand NDR Active Copper cables (ACC) are the lowest cost cabling choice to create high-speed, low-latency connections in an InfiniBand NDR solution. These cables are offered in various lengths and as OSFP and QSFP112 types. Passive DACs use copper wires without any electronics as the connection. These cables consume zero power and have the lowest latency and insertion loss. InfiniBand Active Copper Cables include signal-boosting integrated circuits (ICs) in the cable end to extend their reach.
Overview
NDR optical interconnect is enabled through NDR transceivers usage with fiber cables. NDR transceivers for switches are dual ported and support two NDR links. NDR transceivers for Host Channel Adapters (HCAs) are single ported. Connection between NDR switches and HDR/HDR100 adapters is enabled with Active Optical Cable (AOC) providing OSFP to dual QSFP.
These cables meet the InfiniBand Trade Association (IBTA) standards and are designed for use in supercomputers that have the most stringent requirements.
