Cat6 Network Ethernet Cables 20M
Category 6 cable (Cat 6), is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.
Cat 6 has to meet more stringent specifications for crosstalk and system noise than Cat 5 and Cat 5e. The cable standard specifies performance of up to 250 MHz, compared to 100 MHz for Cat 5 and Cat 5e.
Whereas Category 6 cable has a reduced maximum length of 55 meters when used for 10GBASE-T, Category 6A cable is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100 meter maximum distance as previous Ethernet variants.
Cat6 Cable can work on Cat5 network. It is backward compatible with previous specifications, which means it can be effectively used with Cat5 network. ... Category 6 cable has better specifications than 5 or 5e, enabling it to support faster data transmission when installed with compatible devices.
