CAT6 FAQ - Frequently Asked Questions About Cat6 Cable

Updated: Jul 23

What is a Cat 6 cable

Cat 6 (Category 6) is a cable standard used mainly for Ethernet computer networking, security systems, and telephone services. Cat 6 cable is backward compatible with the Cat 5ECategory 6(Wiki) cable is capable of transmitting voice and data up to 155 Mbps (megabits per second), with possible transmission frequencies up to 550 MHz.




Does Cat6 support gigabit

Cat 6 carries Ethernet 10Base-T, 100Base-TX, and 1000Base-T (Gigabit Ethernet) connections. 

Cat 6 cable is backed with more stringent specifications for crosstalk and system noise than earlier cabling standards.

How many pairs of Cat6

Category 6 cables come with four twisted copper wire pairs and each twisted pair is built of larger 23 gauge copper. 

The earlier model, Category 5, used 24 gauge copper wires. In wire gauges, a larger number indicates a smaller wire.

Can I use rj45 for Cat6

Cat 6 cables are generally terminated with RJ-45 electrical connectors. 

The signal path’s performance will be limited to that of the lowest category if components of the various cable standards are intermixed. 


How to make a Cat6 Patch Cable

Installing Cat 6 cable is thought to be more difficult than Cat 5 or Cat 5E. The main reason behind this is that the conductors are twisted more tightly in Cat 6 cables, 

which makes it more difficult to split them apart. Other than this, everything else is essentially the same as installing Cat 5 or Cat 5E cables.

Cable manufacturing companies provide jacks and panels with much sharper teeth so as to help divide the conductors into pairs and complete the Cat 6 installation cables easily. 

However, while installing Cat 6 cables it is advisable to take a little more time and perform the installation correctly without damaging one’s fingers.


Step 1

This procedure generally applies to Cat 6 RJ45 connectors. An alternate method is given for connectors utilizing a "load bar".
