Difference between Cat5 and Cat6

Technology is evolving at an unprecedented rate and it’s always changing and adapting to meet our modern-day necessities. This constantly evolving ecosystem has given birth to the digital era which keeps on updating, so does everything along with it. Take data capacity, for one which has already reached new heights and the amount of processing power required to handle that much data has also increased and the rate at which data is produced, there’s no easy way to process data requests that big.

Cat5 and Cat6 are by far the most efficient and faster cabling systems used for networking around the world. Cat5 and Cat6 are standardized twisted pair cables used for Ethernet and other networking installations.

What is Cat5?

While more advanced wireless devices continue to proliferate in this technology-focused digital era, wires have always been the backbone of any networking system that requires large-scale data communication.

In order to keep up with the constantly evolving networking ecosystem for faster and efficient data communication, more appropriate cabling is required. Cat5 has been around the networking space for quite some time now. Also goes by “Category 5”, Cat5 comes unshielded with a twisted pair configuration which is a common Ethernet standard cable for computer networks. It’s quite the outdated version of the twisted pair cables that are used presently, although it can efficiently handle speed up to 100 Mbps and support up to 100MHz frequencies.

To meet up the needs of modern networking infrastructures, an updated specification to Cat5 was later introduced. Due to its limitations, the Cat5 configuration has become obsolete and the more enhanced “Cat5e” comes to the picture. The “e” in the “5e” stands for enhanced, which as the name suggests, is designed to a higher standard for more reliable networks. Cat5e significantly reduces signal and noise interference with more stringent specifications for “crosstalk”. The interference created by a network of cables is referred to as crosstalk. The new specifications are able to mitigate the impact of crosstalk. The bandwidth remains the same at 100MHz, but with an increased transfer speed up to 350 Mbps, which is a major upgrade over the conventional 100 Mbps.

What is Cat6?

Then comes the more advanced Cat6 cables, which are more reliable and faster than the Cat5 and Cat5e configuration cables. While both the specification plug into the same ports, Cat6 adheres to the new industry-standard networking specifications. It’s the next iteration of the networking cables which utilizes a thick-gauge plastic casing to reduce signal interference, plus it’s exceptionally faster than the Cat5 and Cat5e. Unlike Cat5, it handles data transfer speeds up to 10 Gbps and supports up to 250MHz frequencies. The idea was to reduce crosstalk to create a more reliable network. It virtually eliminates crosstalk that limits the older cabling standards. As a result, speeds are maintained at larger distances up to 100 meters. However, for 10GBASE-T, the maximum length is reduced to 55 meters.

In order to meet up with the global networking standards, an augmented version of the Cat6 was later introduced, Cat6A. It’s an enhanced industry-level standard among the twisted pair cable configurations and the future of data. The internet is flooded with high-definition video streams and media-heavy websites such as social networking sites and to handle that massive data, a more future-proofed cabling system was required. This is where the Cat6A specification comes to the picture. It’s able to maintain 10 Gigabit speeds for extended lengths, but it lacks the flexibility that is required for a residential deployment. Cat6A are ideal for industrial networking solutions.
