Materials and attenuation

  1. Jan 28, 2006 #1
    Hi to all ... Reading yesterday about optical fibers i have noticed that the fibers have a small attenuation so they are suitable for long distances.. I was wondering where i can find a table that show materials and the atenuation they provide to electromagnetic signals... I am really peculiar to learn this because the classic wires that we use in networks (used for 100Mbits/1000Mbits networks) seem to have even bigger attenuation than the fiber...but still i want to know how much the wires affect the em waves..
