![]() This caused the next version to be released, withĬategory 4 - 20 MHz, for a standard which never really became all that popular.Ĭategory 5 - 100BaseT, which became the standard, and which could (especially at Cat 5e) also support 1000BaseT, or Gigabit Ethernet.ĭue to the way data is encoded, the data rate is actually somewhat higher than analog bandwidth, which is why Cat 5 works at gigabit rates.Ĭategory 6 - 10GBaseT, or 10 Gbit Ethernet. Of course, things were moving quickly, and 100BaseT (and others) soon came out. Basically, the requirements in terms of insertion loss that must be met for a cable to be classified as Cat5 are only specified up to 100MHz. These documents specify performance characteristics and test requirements for frequencies up to 100 MHz. Although it was not specified for data, it was often used at low data rates.Ĭategory 3 - 10BaseT, data rates of 10 Mbit/sec. This is, in part, due to fiber-optic cable already supporting 10 gigabit speed (often written as 10gE, for 10 gigabit Ethernet), rather than by twisted-pair. advanced current technology less sensitive to EMI, electromagnetic interference reduced Next, near-end cross talk data transfer up to 1000 Mbit/s (1Gb/s) supports Gigabit Ethernet comes in solid or stranded 1 B 8 b 1 MB 1024x1024x8 8388608 b 10 Mbps 10000000/8388608 1. The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. At this time, 10 MHz over UTP (100Base-T)had been around for a couple of years, and the standard established 3 categories of cable for signal/data use.Ĭategory 1 - voice/analog only, up to 1 MHz. Cat5E gives an available bandwidth of up to 350MHz, whereas Cat6 almost doubles that with an available bandwidth of up to 550MHz. Cat6 cables simply offer better performance. The max speed of Cat5e cable at 100MHz is what you should expect. #CAT5E BANDWIDTH PATCH#The recommended maximum length cable run length is 90 meters of cable backbone and 10 meters of patch cables. This is the standard which establishes cable categories for voice/data cables for wiring buildings. While a Cat5E Ethernet Cable is currently sufficient for most needs, it is predicted that Cat6 and Cat6A will take over in the future. Cat5e cable according to ANSI/TIA 568.2-D has a maximum speed capability of 100MHz and 1Gb (Gigabit) up to 100 meters (328 Feet). What is the maximum distance for Cat 5 Ethernet cable The maximum length you can run Cat5, Cat5e, Cat6 and Cat6a cable is 100 meters or 328 feet. Cat 5 is suitable to carry Ethernet signals, but also telephony and video. If you start at, and do some more googling, you can find this stuff out.īut start about 1991, when the first version of TIA/EIA-568 came out. The Cat5 cable provides a bandwidth of up to 100MHz, and its speed can range from 10Mbps to a maximum of 100 Mbps. ![]()
