ethernet cable shortest length

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast

main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper cable solutions ca

Forward code: 7 bytes 0x55, a string of 1 and 0 intervals, used for signal synchronization 2. Frame start delimiter: 1-byte 0xd5 (10101011), indicating the start of a frame 3. Da (destination MAC): 6 bytes 4. SA (source MAC):

recommended that 10 GbE be supported at least 5-100 m in cat6 cabling, and m in seven cabling. In addition, we are still investigating whether the shielded cat6 cabling and enhanced unshielded cat6 (sometimes called the E + class) can implement 10GbE within 100 meters. External crosstalk is still A major issue and the discussion is currently centered on A-NEXT, A-PSNEXT, A-FEXT and A-PSFEXT. The tia tr 42 committee in charge of cabling Affairs is developing an enhanced 6-class platform with its

Combined application of Ethernet minimum frame length and TCP/IP @ (computer network) Running the TCP/IP protocol on a fast Ethernet with an average round trip delay of RTT = 20ms, assuming TCP has a maximum window size of 64KB, ask at this time the maximum data transfer rate that the TCP protocol can support is approximately (C)A. 3.2mbit/sB. 12.8 Mbit/sC. 25.
