Difference Between RJ45 and CAT6 Cables.

Difference Between RJ45 and CAT6 Cables. - Table of contents:
RJ45 is a connector, CAT6 is a cable, and both are used for Ethernet. The difference between the RJ45 and the CAT6 Cables is the way the two cables are dedicated.
In the abstract, the RJ45 has pin assignments for all twisted-pair cables in a network connection. Cat6 is also a twisted pair cable for Ethernet purposes.
In the epoch of technology, the internet is way more important than a normal man thinks.
Especially the need for wifi, mobile data, and other wireless internet providers is burgeoning. Over and above for a good WI-FI connection, ethernet cables play a crucial part.
What is RJ45?
RJ45 is part of the Registered Jack connector and its interface standard is number 45. It is used in place of an 8-pin plug or jack for an Ethernet network. It’s called an A1 connector and it’s commonly used to connect networks to Ethernet.
Furthermore, it is based on a local area network (LAN) with a coverage range of 100 to 1000 meters. It has a plastic material at the end of the cable that has eight pins inside. Of the eight pins, four are used to send and receive data, while the remaining four are used for USB or other network roles.

As of now, RJ is available in two wiring designs; T568A and T568B. These two types of pins are used to associate the twisted pair cable with the connector interface. Also, crossover Ethernet cables are ubiquitous and have a T-568A connector on one end and a T-568B connector on the other. This type of crossover is used to connect one computer to another without a hub, router, or switch.
Most computer monitors, attendance machines, consumer machines, credit card machines, tablet computers, etc. have RJ45 interfaces.
What is CAT6?
Back in 2002, the Electronic Industries Association and Telecommunications Industry Association (EIA/TIA) jointly manufactured the cable. Whereas Cat6 is an abbreviated form of Category 6 and was implemented in 2018. It is a twisted-pair cable well-known for Ethernet-based computer networks. Following Cat5e and Cat5, it is more convenient because it produces less noise and crosstalk.
Also, in terms of its performance, the cable can transport networks at speeds up to 10 Gbps and has a standard bandwidth of 250 MHz. Due to the high frequency, Cat6 is the best-twisted pair cable for transferring data at a faster rate.
Unlike RJ45, Cat6 has only four wires for transferring data. Likewise, Cat6 follows LAN operation. However, it is often referred to as MAN, since Cat6 cables can travel up to 100 meters. 10BaseT, 100Base-TX, 10 GBase-T, and other Ethernet networks support Cat 6 cabling.
The main difference between RJ45 and CAT6:
1. Registered Jack-45 is a connector, while the Category 6 cable is twisted pair. The CAT6 end connects to the RJ45 for Ethernet.
2. RJ45 has eight wires, four of which are solid and the other four are striped – white/green, green, white/orange, blue, orange, white/blue, white/brown, and brown. CAT6, on the other hand, has six wires — blue, yellow, white, gray, black, and red pins.
3. After many reports of crosstalk and lengthy systems, CAT5 was replaced by CAT6, where RJ45 was the connector for Ethernet running smoothly.
4. RJ45 provides a speed of 1 Gbps per second, while CAT6 provides a 10 Gbps network connection within a limited range.
5. RJ45 is widely used in Ethernet networks, such as WiFi connections, (LAN) computer networks, and other routes. Although CAT6 is only used as a cable for Ethernet.
| Parameters of Comparison | RJ45 | CAT6 |
|---|---|---|
| Meaning | A registered Jack-45 connector is a data networking interface that connects a device to a Local Area Network (LAN). RJ45 comes up with eight pins under two versions- T-568A and T-568B cables. | Category 6 Cable is a twisted cable for Ethernet and networking routes. CAT5 was replaced by CAT6 due to the frequent crosstalk system. |
| Color Code | There are eight wires- White/Green, Green, White/Orange, Blue, Orange, White/Blue, White/Brown, and Brown. Only 4 wires take action in communication and data transmission. | There are six color codes in CAT6, which Blue, Yellow, White, Grey, Black, and Red. All six pins have distinct properties for Ethernet networks. |
| Applications | RJ45 is primarily used for ethernet networking connectivity with computers, data, WiFi access, and many other networking routes. | CAT6 is a twisted pair cable, which is commonly used for Ethernet and network applications. The end of the CAT 6 cable uses RJ45 connectors for smooth ethernet. |
| Number of pins | RJ45 wired two versions: T-568A and T-568B cables. Each cable has eight different pins(8P8C), four are solid, and the other four are striped. | There are six pins, where Gray, Green, Yellow, and Blue connect the Ethernet and other routes. |
| Date Rate | RJ45 experienced crosstalk from line to line. RJ45 provides 1Gbps per second. | 10 Gbps Ethernet Connections within the range of 30-35 meters and extends to 1Gbps per second within 100 meters. |
All Cat5, Cat5e, Cat6, Cat6a, Cat7, and Cat7a cables use the same RJ45 connectors.
Cat5e RJ45 cable has a lower level of transmission performance, while Cat6 RJ45 cable is optimized with a 250MHz bandwidth, higher data rate, and stronger resistance to crosstalk and noise.
