AmphenolAPH is broadening its AI interconnect opportunity as rising data-center requirements drive demand for high-speed copper, fiber-optic and power interconnect solutions. The company’s IT datacom business, which represented 43% of sales in the second quarter of 2026, grew 89% year over year and 63% organically. AI-related products drove virtually all of the 22% sequential growth, underscoring the increasing role of AI applications in Amphenol’s interconnect business.
APH’s positioning across multiple connectivity technologies gives it exposure to the increasing interconnect content required by AI infrastructure. Its portfolio spans high-speed, power and fiber-optic technologies for data centers, including interconnect systems supporting bandwidth of up to 1.6 terabits per second. This breadth should allow APH to participate across evolving data-center architectures rather than remain tied to a single connectivity approach.
The acquisition of CommScope’s Connectivity and Cable Solutions business further strengthens this opportunity, particularly in optical interconnects. CommScope’s IT datacom business nearly doubled year over year in the second quarter, while IT datacom is expected to account for just under half of its 2026 sales compared with about one-third in 2025.
APH’s expanding AI interconnect exposure is expected to benefit from higher bandwidth requirements, greater optical adoption and increasing power needs across AI infrastructure. Third-quarter IT datacom sales are expected to increase in the mid-teens sequentially, providing a near-term indicator of continued AI-driven demand. With AI infrastructure increasingly requiring more connectivity across multiple layers, APH’s broad interconnect portfolio positions it to capture rising content as data-center architectures evolve.
How APH’s Peers Are Positioned
Amphenol’s close peers TE ConnectivityTEL and Bel FuseBELFB also participate in the AI interconnect market through data-center and high-performance computing applications. TE Connectivity addresses AI interconnect across high-speed copper, optical connectivity, internal cabling and power, covering compute, networking and rack-level applications. Bel Fuse combines connectivity products for high-speed networking with power and magnetic solutions used in servers, networking equipment and data centers. TE Connectivity and Bel Fuse therefore provide relevant exposure to the same AI interconnect buildout as APH, whose IT datacom business is directly benefiting from rising AI-related interconnect demand.
Amphenol’s shares have surged 49.6% year to date, outperforming the broader Zacks Computer & Technology sector’s return of 30.3%.
