اگر دو کابل پروفی باس که مشابه نباشند و امپدانس متفاوتی داشته باشند را به هم متصل کنیم آیا برای شبکه مشکلی پیش نمی آید ؟

بله در صورت عدم تطبیق امپدانس در نقطه اتصال شکل موج سیگنال خراب می شود بویژه وقتی طول کابل زیاد باشد این اثر محسوس تر است . فیلم پیوست را ببینید.

مبحث کابل پروفی باس یکی از مهمترین مباحث هستش که تو پروژه خود مهندسین برق و اتوماسیون هم کم توجهی میکنن بارها برای خود من پیش امده که کابل از نظر ظاهر سالم بوده امده که با تعویض کابل مشکل حل شده و عدم رعایت مرغوب بودن و........ بوده
