Direct Attach Cable (DAC), Twinax
10G, 25G, 40G, 56G, 100G, 200G, 400G мідні кабелі (перепрограмуємі)
Direct Attach (DAC) – бюджетне і більш менш надійне рішення для стекування обладнання. Дозволяє знизити витрати на з’єднання устаткування на швидкостях 10 … 400 Гбіт/с. Потрібно враховувати досить великий радіус вигину кабелю.
