By reducing the original signal rate to 1 ⁄ 4 or 1 ⁄ 2, the link speed drops to 2.5 or 5 Gbit/s, respectively. [5] The spectral bandwidth of the signal is reduced accordingly, lowering the requirements on the cabling, so that 2.5GBASE-T and 5GBASE-T can be deployed at a cable length of up to 100 m on Cat 5e or better cables. [6] [7]
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and Cat 6). Autonegotiation is a requirement for using 1000BASE-T [6] according to Section 28D.5 Extensions required for Clause40 (1000BASE-T). [7]
Synchronous Ethernet clocks, based on ITU-T G.813 clocks, are defined in terms of accuracy, noise transfer, holdover performance, noise tolerance and noise generation. These clocks are referred as Ethernet Equipment Slave clocks. While the IEEE 802.3 standard specifies Ethernet clocks to be within ±100 ppm. EECs accuracy must be within ±4.6 ppm.
Jumbo frames can increase the efficiency of Ethernet and network processing in hosts by reducing the protocol overhead, as shown in the following example with TCP over IPv4. The processing overhead of the hosts can potentially decrease by the ratio of the payload sizes (approximately six times improvement in this example). Whether this is ...
The Network Driver Interface Specification (NDIS) is an application programming interface (API) for network interface controllers (NICs). Specification [ edit ]
