The Difference Between CAT5e and CAT6

With the growing need for higher bandwidth and faster networks, CAT5e and CAT6 are increasingly being applied to people's lives. At present, in this family for twisted-pair, and CAT3, CAT5 and CAT7 than twisted-pair, CAT5e and CAT6 most widely the application scope of these two kinds of twisted-pair.

Although CAT5e and CAT6 are in the same position, that doesn't mean that CAT5e and CAT6 can be substituted for each other. Consumers still need to master the characteristics of the two to make better choices based on their online needs. So what's the difference between CAT5e and CAT6?

First of all, the main difference between the CAT5e and CAT6 is the performance. CAT5e and CAT6 system although can transmit gigabit network, but the CAT5e of network transmission adopts standard is 1000 base-t, but 1000 base-Tx is CAT6 working method. In this regard, the CAT5e is "capable" of supporting gigabit Ethernet, while the CAT6 is "truly guaranteed" using gigabit Ethernet.

CAT6, therefore, more can adapt to the current architectural environment, especially in those who focus a lot of twisted pair and has many places of interference sources, such as with many electrical appliances (computer, phone, all kinds of production equipment, etc.) in equipment room, power lines, and flare path adjacent place. From the perspective of 1000base-t and 1000base-tx, the reasons for this difference are further revealed.

The 1000base-t typically USES four pairs of twisted wires to complete 1000Mbps data transfer, and each pair of double stranded wires delivers 250Mbps of data flow. But because only CAT5e design of bandwidth of 100 MHZ, 1000 MBPS to implement bidirectional transmission network, it must meet four on line all use (full duplex), each pair of lines to support the data rate of 250 MBPS (each direction), sending about 125 m symbols, etc.

But on the other side, because each link has to be sent in two directions, it increases the probability of error. Full-duplex operation network equipment, therefore, need to increase the quantities of crosstalk/echo cancellation DSP processor, network equipment can correctly identify each square wave signal, it also caused the support an average of 1000 base-t switch port cost increase greatly.

The 1000base-tx is also based on four pairs of double stranded wires, but it is two pairs of lines that send signals, two pairs of lines receive signals, and the wire itself is not transmitted in two directions. As a result, the crosstalk between cables is greatly reduced, further reducing the cost of network interfaces. A little less efficient but due to the use of the cable, to achieve 1000 MBPS transmission rate, and more than 100 MHZ bandwidth requirement, so CAT5 and CAT5e does not support this type of network, only CAT6 can support.

By the above analysis can be obtained, because use the workings of a 1000 base-TX, relatively in CAT5e, CAT6 has stronger anti-jamming ability, this characteristic can be widely used in various places.

Secondly, there are also obvious differences in structure, CAT5e and CAT6. CAT6 increased cross the skeleton of the insulation, the four pairs of line of twisted pair separately under cross skeleton four grooves, and the conductor of the cable diameter is big, small torque and outer diameter and more coarse. The new manufacturing process for this central cross is also designed to avoid crosstalk from the network of the 1000base-t network.

In addition, the CAT6’s price is higher than CAT5e. It is one of the factors CAT5e which relatively widely used in the now.

From the perspective of the current market, CAT5e is still one of the integrated wiring project mainstream products, its excellent performance and better support the flow of the network. Although it is said that CAT6 is better than CAT5e, it is still mainstream. It is believed that with the development of the times, the CAT6 will gradually penetrate into the integrated wiring and gradually replace the CAT5e.
