It is the successor to 100Base-TX and enables ten times higher speeds with similar cabling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most important features:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cabling:<\/strong><br>1000Base-T uses four twisted wire pairs in network cables of category 5e or better (Cat5e, Cat6).<br>Unlike 10\/100 Mbit\/s, all four pairs are used simultaneously. Transmission takes place in both directions simultaneously (full duplex) on each pair. This is how the high data rate of 1 Gbit\/s is achieved.<\/li>\n\n\n\n<li><strong>Transmission speed:<\/strong><br>maximum 1 Gbit\/s<\/li>\n\n\n\n<li><strong>Maximum cable length per connection:<\/strong><br>100 m between end device and switch\/hub<\/li>\n\n\n\n<li><strong>Topology:<\/strong><br>Star-shaped - each end device has its own line to the central network device<\/li>\n\n\n\n<li><strong>Compatibility:<\/strong><br>1000Base-T is downwards compatible with 10Base-T and 100Base-TX. Devices automatically negotiate the highest possible speed when establishing a connection (\"auto-negotiation\").<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These properties make 1000Base-T suitable for modern networks with high data volumes, e.g. for servers, workstations, VoIP or multimedia applications. It is now the standard in most office and home networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is a clear comparison table for the three standards:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>Feature<\/strong><\/th><th><strong>10Base-T<\/strong><\/th><th><strong>100Base-TX<\/strong><\/th><th><strong>1000Base-T<\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>IEEE standard<\/strong><\/td><td>IEEE 802.3 (Clause 14)<\/td><td>IEEE 802.3u<\/td><td>IEEE 802.3 (Clause 40)<\/td><\/tr><tr><td><strong>Designation<\/strong><\/td><td>Ethernet<\/td><td>Fast Ethernet<\/td><td>Gigabit Ethernet<\/td><\/tr><tr><td><strong>Max. transmission rate<\/strong><\/td><td>10 Mbit\/s<\/td><td>100 Mbit\/s<\/td><td>1 Gbit\/s<\/td><\/tr><tr><td><strong>Cabling<\/strong><\/td><td>Twisted pair, Cat3 or better<\/td><td>Twisted pair, Cat5 or better<\/td><td>Twisted pair, Cat5e or better<\/td><\/tr><tr><td><strong>Used wire pairs<\/strong><\/td><td>2 pairs (1x transmit, 1x receive)<\/td><td>2 pairs (1x transmit, 1x receive)<\/td><td>4 pairs (transmit + receive simultaneously)<\/td><\/tr><tr><td><strong>Max.
