High-Speed & Fiber Optic

High-speed and fiber optic circular connectors integrate Quadrax, Octonet, and differential-pair insert technologies into standard MIL-DTL-38999 and MIL-DTL-83723 shell formats, enabling data rates from 1 Gbps to multi-gigabit Ethernet over the same circular footprint already qualified on platform wiring. Quadrax contacts carry four conductors in a shielded arrangement suited to 100BASE-T1 and AFDX networks; Octonet inserts extend this to eight differential pairs for higher bandwidth. Fiber optic inserts allow single-mode and multi-mode optical links within a circular shell, eliminating EMI susceptibility at the interconnect level. Amphenol Military High Speed specializes in high-speed insert solutions qualified to defense environmental requirements. Amphenol Aerospace and Amphenol Socapex supply shells and hybrid insert configurations. Amphenol Canada and Amphenol India provide manufacturing capacity for high-volume programs. These connectors are specified on platforms including F-35, P-8 Poseidon, and ground vehicle vetronics.
