Category 6 Ethernet Cable Specifications

Draft specification ansi tia eia 568 b 2 10 specifies cable systems called augmented category 6 or more frequently as category 6a that operate at frequencies up to 500 mhz and will provide up to 10 gbit s bandwidth.

Category 6 ethernet cable specifications. Cat8 cable or category 8 cable is an ethernet cable which differs greatly from the previous cables in that it supports a frequency of up to 2 ghz 2000 mhz and is limited to a 30 meter 2 connector channel while cat8 cable requires shielded cabling as well. The cat6a doubles data transmission bandwidth from 250 to 500 mhz. Most importantly cat8 ethernet patch cables can support a speed of 25 gbps or even 40 gbps. Let s look at the technical and physical differences in ethernet cable categories to help us decide.

Ethernet cables are grouped into sequentially numbered categories cat based on different specifications. The category 6a or cat6a cable is the latest iteration of gigabit ethernet cabling. Cat 6 cables technically support speeds up to 10gbps but only do so for up to 55 meters. The cable standard specifies performance of up to 250 mhz compared to 100 mhz for cat 5 and cat 5e.

Category 5 cable cat 5 is a twisted pair cable for computer networks since 2001 the variant commonly in use is the category 5e specification cat 5e the cable standard provides performance of up to 100 mhz and is suitable for most varieties of ethernet over twisted pair up to 1000base t gigabit ethernet. That speed comes with a price however as cat 6 cables are more expensive than cat 5 and cat 5e variants. The new 2ghz speed limit. 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.

If you re installing an ethernet network you ll need to make a decision about the type of cable to use for the permanent connections between network jacks. Cat 5 is also used to carry other signals such as telephony and video. Also aimed at data centers and requiring high speed gear the cables run at 1 or 2ghz and can move. Sometimes the category is updated with further clarification or testing standards e g.

And provides superior reliability and transmission. The new specification has limits on alien crosstalk in cabling systems. Finally category 8 is the new spec on the cable block. Cat 6 has to meet more stringent specifications for crosstalk and system noise than cat 5 and cat 5e.

Cat 6 supports 10 gigabit ethernet only up to 164 feet of cable length. Decreases the chance of crosstalk interference.
