Where Amphenol sits in the stack
Amphenol's placements in this catalog cover 5 parts, from layer 3 (networking & interconnect) to layer 4 (servers, racks & integration). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Copper: DAC / ACC / AEC cables — High-speed copper cable assemblies — DAC, ACC, and AEC types — that link GPUs, NICs, and switches over short distances as a lower-cost alternative to optical transceivers.
- NVLink copper spine / backplane cartridges — The copper cable assemblies and backplane cartridges that physically wire the scale-up fabric together inside a rack, most visible in Nvidia's NVL72 architecture.
- Board-level connectors & sockets — The physical connectors — CPU and GPU sockets, board-to-board and cable connectors, and I/O cages — that link chips, trays and cables together on and between boards.
- OSFP/QSFP cages — The metal cages mounted on switch and NIC boards that mechanically receive and shield pluggable OSFP or QSFP optical and copper transceiver modules.
- In-rack busbar & power whips — The high-current busbar and cabling that carries power from the rack's power shelves to each tray, including Nvidia's specified ±48 V / 1,400 A busbar used in rack-scale liquid-cooled systems.
