Hello www.Antionline.com I have a question If high security is a primary factor in designing a LAN, what type of cable is the best choice? I think fiber, Because the signals in fiber-optic cable are not detected by electronic eavesdropping equipment, and also it is extremely hard to tap. The network fails completely when the cable is cut. But I heard some guys say (10base5) is a better cable for a LAN, which one is better? Or what would you recommend?
