English term or phrase: feedthrough
Здравствуйте, коллеги!
Вот отрывок из текста по корпусированию:

"Optic-electronic device packages are made by metal-wall and ceramic feedthrough, they provide electronic and optic tunnels for the signals and provide hermitic carrier interconnection for the chips. They can be 50 Ом impedance and can work up to 2.5Gbps, 10Gbps, 25Gbps, 40Gbps and 100Gbps. Product parameters, hermeticity and reliability can meet international standards. They can be designed and developed according to customer’s requirements."

Скажите, как обозвать "feedthrough" ? Просто проходное отверстие, по аналогии с проходным конденсатором?

Был бы премного благодарен за небольшой ликбез по поводу отличия Feedthrough от Via )

Explanation:
feedthrough - это достаточно распространенный термин в разных областях техники и практически везде он переводится как ввод (имеется в виду ввод через что-то)
Вот определение сабжа из Википедии https://en.wikipedia.org/wiki/Feedthrough
A feedthrough is a conductor used to carry a signal through an enclosure or printed circuit board.
А вот аналогичное описание из нашего ГОСТ Р 52287—2004 (МЭК 60772) https://files.stroyinf.ru/Data2/1/4293854/4293854370.pdf
Вводы обеспечивают газонепроницаемое и герметичное проникновение через оболочку одной или нескольких электрических цепей.
Правда, это ввод для ядерных реакторов, но термин универсальный

А вот описание сабжа из патента https://patents.google.com/patent/US5374786
A feedthrough for an electronic package comprising:
(a) a ceramic material having an external wall and an aperture in said ceramic material extending to said external wall;
(b) a highly electrically conductive lead disposed in and extending through said aperture and externally of said external wall; and
(c) a washer having substantially the same coefficient of thermal expansion as said ceramic material, disposed around said lead and said aperture and secured to said external wall of ceramic material and to said lead to provide an hermetic seal with said external wall and said lead
Аналогичные вводы используют в конструкциях электрических машин, мощных трансформаторов и т.п.

проходные изоляторы


Explanation:
В обиходе электронщиков - просто "проходники". Так, кстати, можно и написать

керамические проходные изоляторы с отверстием(ями) для оптоволокна или провода(ов)

Их форма может быть самой разной. Чаще всего, это просто одна из стенок корпуса микросхемы с отверстием

Проходные изоляторы и линейные вводы
