No matter Cat6 or Cat5e are both unable to support 10G Base-T of 100 meters. Therefore, relative to the prerequisites of the IEEE 802. 3 organization TR42. 7 Commission in 2003 began a survey of a new generation of cable, eventually enacted TIA/EIA-568-B. 2-10 of standard in 08. They redefined the prerequisites of the category 6A cable relative to the standards of the 10GBase-T
First of all, the requirement of class 6A system bandwidth up to 500Mhz, introduced a brand of crosstalk between the indicator and test. Category 6A system totally fulfills the applications of 10G Base-T of 100 meters. At present, based on horizontally sprained pair Gigabit transmission equipment is not very popular, but taking into account the quality assurance of integrated electrical wiring system 25 years and at least 15 years of usage time.
It will bring huge cost to switch the electrical wiring system and relocation. The cost of 10 G Base-T networks has been reduced from 8 to 9 times in 2004 to two to three times compare with 1000Base-T and it will be further reduce with the wide range of applications.
Compared with the cost of 10 GB/s fiber optic network, 10G base-T is only about 20%. As for the higher flow requirement data center, a good 6A cabling system is a foundation for future expansion and development.
Cat7 can also support 10G base-t, however considering its cost and versatility, the Cat6e is still the best solution for 10 Gigabit.
