How to Create a Connection Between RJ45 Connector and Cat6

January 02, 2022 3 min read

The CAT6, derived from Category 6, was released just a few years after CAT5e. CAT6 is a standardized twisted-pair Ethernet cable, backwards compatible with CAT5/5e and CAT3 cable standards. Like CAT5e, CAT6 cables support Gigabit Ethernet segments up to 100 m, but also allow use in 10-Gigabit networks over a limited distance. In the early part of this century, CAT5e typically went all the way to workstations, while CAT6 was used in the backbone infrastructure of routers and selectors.

CAT6 can handle speeds of up to 1000 Mbps or one Gigabit per second. This value is more than enough for the speed of most internet connections. There is a small chance that you currently have an internet connection that can reach speeds of 500 Mbps. CAT6 cables are designed for operation at frequencies up to 250 MHz. This means that CAT6 cable can process more data at the same time. .


RJ45 is a type of connector commonly used forEthernet, ie networking. It looks similar to a phone jack, but is a little wider. Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are also called RJ45 cables.

The "RJ" in RJ45 stands for "registered jack" as it is a standardized network interface. The "45" simply refers to the interface pattern number. Each RJ45 connector has eight pins, which means that an RJ45 cable contains eight separate wires. If you look closely at the end of an Ethernet cable, you can see eight wires, each a different color. Four of them are solid colors while the other four are striped.


Cat6 cables are used in the LAN Networks, making it essential to have a specific type of connecting end. RJ45 Connectors can help in this regard. To create a secure & quick connection between RJ45 Connector and Cat6 cables, follow this step-by-step process.

The process is straight forward, but it might be a bit time-consuming for the newbies because of multiple wire strands.


  1. Cut the insulation of a Cat6 cable using the wire cutter. Make sure to remain gentle as we need to cut only the insulation without harming the wires within.
  2. You’ll see a set of 8 wires with a single strand and a filtering material. You can move all the wires aside and cut the extra strand and the filtering material with the wire cutter.
  3. Unwind the wire sets, you’ll have eight single wires at the end of the process. 
  4. Arrange them with the B formatting of wire, which is as follows:
  • White/Orange (Transmit +)
  • Orange (Transmit -) 
  • White/Green (Receive +)
  • Blue
  • White/Blue
  • Green (Receive -)
  • White/Brown
  • Brown
  1. Now slide the wires into the RJ45 connector so that the orange wires are closest to you and the flat side of the connector is at the bottom. 
  2. Once the wires are inside the RJ45 connector, cut any extra wires so they can easily get into the other part of the RJ45 connector. 
  3. Hold the outer part of RJ45 Connector with the clip at the bottom. Now slide all the eight wires already covered with the inner part of the connector. As these wires will reach the end, you’ll hear a “click” sound. This ensures that your connector has been fixed properly.
  4. Now place this connector in the crimping tool and squeeze it to ensure its sustainability. Your connection is ready.
