<P> 10BASE5 (also known as thick Ethernet or thicknet) was the first commercially available variant of Ethernet . 10BASE5 uses a thick and stiff coaxial cable up to 500 metres (1,600 ft) in length . Up to 100 stations can be connected to the cable using vampire taps and share a single collision domain with 10 Mbit / s of bandwidth shared among them . The system is difficult to install and maintain . </P> <P> 10BASE5 was superseded by much cheaper and more convenient alternatives: first by 10BASE2 based on a thinner coaxial cable, and then once Ethernet over twisted pair was developed, by 10BASE - T and its successors 100BASE - TX and 1000BASE - T. As of 2003, IEEE 802.3 has deprecated this standard for new installations . </P>
