The yellow-cable (also known as 10BASE-5, thicknet) is one of the several physical media specified in the IEEE 802.3, used in Ethernet-based local networks (Local Area Network - LAN). It is based on a thick coaxial cable, which can be used in 500-metre segments without amplification. Its speed, just like other media in the specification, is 10Mbit/sec, indicated by the number 10 at the beginning of the type designation. The number 5 indicates the 500-metre maximum cable length. As bandwidth demands increased, the 10BASE-5 was later replaced by the faster and cheaper CAT 5 Ethernet twisted-pair cable and the popular 802.11 wireless network solution.
