Amphenol

Robot power, data & sensor connectors

HUMANOID ROBOT

Where it fits in the robot

Amphenol explicitly maps interconnect products to humanoid power distribution, control, vision, and sensing systems.

What the evidence establishes

Humanoid evidence

Amphenol explicitly maps humanoid interconnects. It supplies electrical connections, not complete sensors, camera processors, or battery cells.

An explicit humanoid product, development program, application, or partnership. This does not establish revenue, market share, or production volumes.

Checked. This is the research review date, not the source publication or quote time.

Keep in perspective

Connectors are enabling components across many industries; humanoid-specific revenue is not separately established.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. A robotics product or development announcement does not by itself establish material humanoid revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Readout & interface board

Timing, power, and interface electronics transfer image data to the robot’s perception computer.

Scope of the company links: Camera systems, readout/control silicon, and interface connectors. Amphenol supplies interconnects, not image processors.

Compute carrier board

The circuit board routes power and high-speed signals between compute, memory, and peripherals.

Scope of the company links: Compute modules and reference platforms, plus board interconnects (Amphenol) and power electronics (MPS). Not bare-PCB fabrication.

Cell interconnects

Tabs join each parallel pair, then connect the four groups in series. Series groups add voltage; parallel cells add capacity. Five distinct nodes support group-voltage measurement.

Scope of the company links: Battery power interconnects are Amphenol’s related role; supply of the illustrated welded cell tabs is not established.

Base & electrical connector

A fixed mount anchors the sensor; the connector carries power and measurement data to the robot.

Scope of the company links: Sensor integrators provide mounting bodies; TE and Amphenol provide relevant electrical interfaces. Their roles differ.

AI SERVER RACK

Where it fits in an AI server rack

Describes itself as an interconnect provider to makers and operators of internet and AI-enabling systems, with high-speed, power and fiber-optic products; IT datacom was about 36% of 2025 sales. NVIDIA lists Amphenol among Blackwell infrastructure partners (Oct 15, 2024); with Semtech it launched a 1.6T active copper cable for AI (Apr 1, 2025); it closed the CommScope connectivity and cable purchase on Jan 9, 2026; Q2 2026 sales were $8.8B, up 55%.

What the evidence establishes

AI-rack evidence

Disclosed: Amphenol’s 2025 10-K describes its AI interconnect role; NVIDIA’s OCP post names it among Blackwell infrastructure partners.

An explicit AI-server or AI-rack product, design-in, supply role, program, reference design or partnership, such as a part named for rack-scale AI systems or a product sold for AI data centers. For a rack builder, it means the company’s own AI servers or racks. This does not establish revenue, market share, volumes or future sourcing.

EvidenceDisclosed: Amphenol’s 2025 10-K describes its AI interconnect role; NVIDIA’s OCP post names it among Blackwell infrastructure partners.
How we knowDisclosed The company’s own filing, release, annual report, product page or investor record describes the AI-server or AI-rack role. Where customers are unnamed, the listing says so.
Primary sourceAmphenol — supporting disclosure
Company or official disclosure; vendor claims are attributed to their source.
Checked. This is the research review date, not the source publication or quote time.

Keep in perspective

Amphenol names no AI customer. Its widely cited role as the initial source of the NVL72 NVLink cable backplane (Paladin) comes from SemiAnalysis (Jul 2024), not from Amphenol or NVIDIA, and IT datacom sales include non-AI products.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. An AI-server product, design-in or partnership does not by itself establish material AI-rack revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Copper cable spine

More than 5,000 copper cables, grouped in cartridges at the rear of the rack, link every compute tray to every switch tray without converting signals to light.

Scope of the company links: In GB200/GB300 NVL72, four NVLink cartridges at the rear hold over 5,000 copper cables joining the 1RU compute and switch trays (NVIDIA OCP contribution, Oct 15, 2024; NVIDIA calls them ‘active copper cables’, while most descriptions treat them as passive twinax). NVIDIA names no cartridge supplier. Luxshare says its Intrepid Cable Cartridge cable-backplane is in commercial use in certain mainstream AI clusters. SemiAnalysis (Jul 2024) reports Amphenol’s Paladin backplane as the initial primary source, an analyst attribution neither company confirms. TE markets Slingshot 224G cabled-backplane connectors with its own 224G cable for AI. Later NVIDIA designs may change the spine; that is not verified here.

High-speed connectors

Blind-mate connectors where each tray docks into the cable spine. Hundreds of tiny contacts must align within fractions of a millimetre as the tray slides in.

Scope of the company links: Blind-mate backplane and near-chip connectors: Amphenol’s Paladin HD 224G backplane interconnect (the NVL72 attribution is SemiAnalysis’s, not the company’s), TE’s AdrenaLINE Catapult near-chip and Slingshot 224G backplane connectors for AI/ML, and Luxshare’s 224G Intrepid NEXUS backplane connector and KOOLIO CPC/NPC, which it says are in commercial AI-cluster use. NVIDIA lists Molex (private, a Koch subsidiary) and LOTES among Blackwell partners without stating their parts; LOTES is not mapped.

Active electrical cables

Copper cables with a retimer or DSP chip in each plug that cleans up the signal, extending copper’s reach to several metres at a fraction of the power of optics.

Scope of the company links: Copper cables with signal chips in the plugs, mostly for NIC-to-switch and switch-to-switch links. Credo sells complete ZeroFlap AECs to hyperscalers; Marvell’s Alaska A 1.6T AEC DSP names Amphenol, Molex and TE as cable partners (Jun 27, 2024); Astera Labs sells Aries and Taurus smart cable modules for AECs; BizLink and Luxshare sell retimed active copper cables (Luxshare showed a 1.6T OSFP AEC at OCP 2025); Microchip sells the META-DX2C 800G AEC retimer. Semtech’s CopperEdge redrivers power linear active copper cables (ACCs), such as Amphenol’s 1.6T OSFP ACC, a lower-power alternative to retimed AECs. No source ties a specific cable to NVL72. Montage launched PCIe 6.x and CXL 3.x AEC solutions in January 2026.

Fiber & cabling

High-density optical fiber cables and multi-fiber connectors that carry the light from the rack to the cluster’s switches.

Scope of the company links: Fiber cable, MPO/MMC connectivity and patching from the rack to the network. Corning will raise US optical-connectivity capacity 10x under its May 2026 NVIDIA partnership; Fujikura’s AFL says an NVL72 rack can be fed with up to 1,152 fibers and sells ultra-high-fiber-count cable; Furukawa’s Lightera mass-produces a 13,824-count cable for AI hyperscale data centers; Sumitomo Electric markets a 6,912-fiber cable and high-density connectors; Browave, a Taiwanese passive-optics maker, is in NVIDIA’s CPO ecosystem. SENKO, also named by NVIDIA, is private. The SDM4 multicore-fiber MSA (AFL, Corning, Sumitomo Electric, TeraHop) is a specification, not a product. Other listed cable and connector makers were not verified for AI fiber in our September 2026 review. Amphenol added fiber connectivity with the CommScope connectivity and cable business it bought (closed Jan 9, 2026), and BizLink sells fiber cassettes.

Quick disconnects

Dripless couplings at each tray connection. They seal both sides when unplugged, so a tray can be removed without draining the loop.

Scope of the company links: Fositek says its UQDs entered the GB200/GB300 supply chain and passed Rubin testing (2025 annual report); Envicool says NVIDIA listed its UQDs (OCP 2024) and its UQDs and MQDs (OCP 2025) among MGX ecosystem partners; Auras shows quick disconnects in its AI liquid-cooling line-up; Amphenol markets UQD, UQDB, BMQC and MQD couplings for AI data-center liquid cooling; Dover’s CPC is an NVIDIA-named Blackwell partner and Dover’s 10-K cites connectors for liquid cooling of server racks; JetCool (Flex) offers manifolds and quick disconnects. Parker was not verified as a quick-disconnect supplier in our sources, and Nidec’s quick couplings are made for its own CDUs. Stäubli and Danfoss, both NVIDIA-named, are private. Luxshare lists blind-mate quick connectors for AI racks.

QUANTUM COMPUTER

Where it fits in a quantum computer

Owns XMA Corporation (acquired in 2023, about $15 million of annual sales), which calls itself the industry leader in cryogenic RF passive components for quantum computing and sells attenuators (including bulkhead types), terminations, DC blocks and IR filters rated to 4 K, and Narda-MITEQ (acquired in May 2025, about $120 million of annual sales), whose CLNA cryogenic amplifiers are qualified down to 4 K and marketed for quantum computing. Japan’s September 2025 supply-chain roadmap by AIST, RIKEN, Fujitsu and NEC says XMA’s cryogenic SMA attenuators are among the most used, that XMA Amphenol now sells IR filters as products, and that Narda-MITEQ room-temperature amplifiers are relatively popular for qubit readout.

What the evidence establishes

Quantum-computing evidence

Partner-disclosed: the AIST–RIKEN–Fujitsu–NEC roadmap names XMA and Narda-MITEQ products, Amphenol’s filings confirm both acquisitions, and XMA’s and Narda-MITEQ’s product pages describe the quantum-computing parts.

An explicit quantum-computing product, design-in, supply role, program or partnership, such as a part sold for quantum computers or a named quantum-computer customer. For a maker, it means the company’s own quantum computers or processors. This does not establish revenue, market share, volumes or future sourcing.

Keep in perspective

Both units are small parts of Amphenol’s Harsh Environment Solutions segment, and Amphenol reports no quantum sales. The roadmap describes use in Japanese research institutions rather than purchases by a named quantum-computer maker, and Amphenol’s larger RF connector lines were not checked for cryogenic use.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. A quantum-computing product, design-in or partnership does not by itself establish material quantum revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Attenuators

Small cryogenic attenuators bolted to the plates on every input line. Each absorbs most of the signal together with the thermal noise from warmer stages above.

Scope of the company links: Attenuators anchored at 4 K, the cold plate and the mixing chamber strip thermal noise from input lines. Amphenol is mapped through XMA, which sells cryogenic attenuators (including bulkhead types), terminations and DC blocks for quantum computing and which Japan’s 2025 AIST–RIKEN–Fujitsu–NEC roadmap names among the most used cryogenic SMA attenuators; Huber+Suhner sells 0–20 dB cryogenic attenuator blocks and ganged attenuators in its multicoax system; QuantumCTek sells cryogenic attenuators with its cable assemblies. Private alternatives include API Technologies, Radiall, Quantum Microwave, CryoCoax and Delft Circuits (attenuators on the flex). Smiths Interconnect, now owned by Molex, makes RF attenuators, but no cryogenic quantum line was found.

Filters & IR absorbers

Low-pass and band-pass filters and infrared-absorbing filters that block stray high-frequency radiation, which would otherwise break the qubits’ superconducting pairs.

Scope of the company links: Low-pass, band-pass and infrared filters keep stray radiation and out-of-band noise off the qubits. Amphenol’s XMA sells cryogenic IR filters (the AIST roadmap says IR filters, once home-made by researchers, are now sold as products by XMA Amphenol and Kawashima Seisakusho), Huber+Suhner builds IR filters into its multicoax system, and QuantumCTek sells cryogenic filters with its cable assemblies. Qnity is mapped as an upstream material supplier: its Laird Eccosorb absorbers are cast into IR filters, as in ETH Zurich’s Eccosorb CR-124 filter. Conventional low- and high-pass filters come mostly from private Mini-Circuits and RLC Electronics; the roadmap also lists a ‘K&L’ filter maker, which we did not tie to Dover. Bluefors, Quantum Microwave and Delft Circuits sell private IR-filter products.

HEMT amplifier

A low-noise amplifier built from high-electron-mobility transistors and anchored at 4 kelvin, where cooling keeps its added noise low.

Scope of the company links: Cryogenic HEMT low-noise amplifiers on the 4 K plate. AmpliTech sells HEMT amplifiers it markets for quantum computers (a 6–8.5 GHz model with 42 dB gain, 2 K noise and 4 mW, per the AIST roadmap), and Amphenol’s Narda-MITEQ sells CLNA cryogenic amplifiers qualified to 4 K and marketed for quantum computing. Private Low Noise Factory holds a high share in superconducting-qubit research; Cosmic Microwave Technology (licensed Caltech designs) and Nihon Tsushinki (a 2026 NEDO project on integrated cryogenic amplifiers) are other private makers. No source tied Northrop Grumman’s InP HEMT process to these amplifiers.

Room-temperature amplifiers

Low-noise amplifiers outside the refrigerator that raise the signal to the level the down-conversion and digitizing electronics need.

Scope of the company links: Low-noise amplifiers at room temperature that lift the readout signal before down-conversion; the parts are generic and many vendors qualify. The AIST roadmap names Narda-MITEQ (Amphenol) and private B&Z Technologies as relatively popular, and AmpliTech sells LNAs from 50 kHz to 44 GHz for markets including quantum computing. Mini-Circuits (private) is also common. Qorvo and MACOM sell general-purpose LNAs but showed no quantum-specific role, so they are not mapped.
