Чтобы хорошо разбираться в программировании трансиверов, нужно в первую очередь изучить стандарты и спецификации.
Мы сделали подборку стандартов MSA для трансиверов самых популярных форм-факторов. В этом списке вы найдете наименования и прямые ссылки на документы под соотвествующие типы трансиверов.
