Cat 5 Vs Cat 6: What Are The Foremost Variations?


Granted, ethernet cables aren’t essentially the most thrilling subject on the planet. Nevertheless, selecting the improper cable class in your networking setup might see you lose treasured web velocity – one thing that might doubtlessly have a knock-on impact in your gaming efficiency and shopping enjoyment.

While each Cat 5 vs Cat 6 cables do an awesome job of connecting your pc or server to a modem, one undoubtedly brings a little bit extra to the desk. Many individuals most likely don’t give a second thought in the case of cables, nonetheless, you most likely ought to.

Within the following article, we’ll be lifting the lid on the variations between Cat 5 and Cat 6 cables, making the topic a a lot easier-to-digest subject.

So, with lots to get by way of, let’s waste no additional time and dive straight into it!

What Is A Class 5 Cable?

So, what precisely is a Class 5 cable? Effectively, in its easiest type, a Class 5 cable is a networking cable used to attach your pc or server to a modem. While this isn’t the one use for a Class 5 cable, it’s undoubtedly the most well-liked utilization in immediately’s client market.

The cable is designed with 4 twisted pairs of copper wire which assist to cut back noise discount within the cable. Most Cat 5 cables are utterly unshielded which means, with out this design (alongside the differential signaling), you’d expertise some type of noise interference.

Class 5 Requirements

Taking a look at requirements, the specification for Class 5 cables is outlined in ISO/IEC 11801, IEC 61156, and EN 50173. That mentioned, the specification was outlined by ANSI/TIA/EIA-568-A, providing up efficiency traits for frequencies as much as 100 MHZ.

Shoppers can get Class 5 cables in each stranded and stable conductor types – each of which supply distinctive traits reminiscent of flexibility and solid-core design. The class and kind of cable are nearly at all times printed on the aspect of the cable, letting precisely what you’re buying.

Cat 5 cables are extremely fashionable, utilized in most workplace environments or LANs throughout the nation. Having mentioned that, the most recent customary of Cat 5 cable used inside most fashionable methods is Cat 5e – launched in 2001 and providing a slight enchancment over Cat 5.

As we mentioned earlier, the Cat 5 cable customary can successfully deal with 10/100 Mbps speeds at a fee of 100 MHz bandwidth. While this was traditionally thought-about greater than sufficient for many common use functions, newer variations quickly began to push Cat 5 cables out.

Property Nominal Tolerance
Attribute impedance between 1–100 MHz 100 ± 15
Attribute impedance @ 100 MHz 100 ± 5
DC loop resistance ≤ 0.188
Propagation velocity (Relative to the velocity of sunshine) 0.64
Propagation delay 5.3
Delay skew (< 100 MHz) < 0.20
Capacitance at 800 Hz 52
Max tensile load (throughout set up) 100
Wire diameter 0.51
Temperature −55 to +60
Most working voltage 125

What Is A Class 6 Cable?

Class 6 cables are similar to Cat 5, using a twisted pair design that’s nice for ethernet and LAN networking. The Class 6 cable is totally backward appropriate with Cat 5e and Cat 3 requirements. Nevertheless, Class 6 cables have to satisfy extra stringent specs for system noise and crosstalk – when in comparison with Cat 5.

Class 6 gives up the identical 4 twisted copper wires design as Cat 5, though it’s rather more useful and versatile.

Class 6 Requirements

Taking a look at requirements, Cat 6 cables, like Cat 5, may also be recognized by the printer on the aspect of the cable sheath. Cable varieties are, once more, outlined by ANSI/TIA-568 requirements. Cat 6 cables have been utilized since June 2002, after TIA (telecommunications business affiliation) revealed it.

The Cat 6 cable gives up a efficiency increase over Cat 5, with the previous offering speeds of as much as 10 Gbps and bandwidth of 250 MHz. As acknowledged earlier, Cat 6 cables are totally backward appropriate with Class 5/5e and Class 3 cables.

Like Cat 5, Class 6 quickly developed to Cat 6A – characterised by as much as 500MHz  bandwidth for improved alien crosstalk and permitting 10GBASE-T to achieve lengths of 100m.

  Conductor Diameter (inches) Max Size AWG Frequency (MHz) Energy Over ethernet
Cat 5e 0.0201 100m 24 100 YES
Cat 6 0.0201 or 0.0226 100m (55 for 10 GB/s) 24 or 23 250 YES
Cat 6A 0.0226 100m 23 500 YES
Mini Cat6 0.0126 10m 28 550 YES

Bodily Variations Between Cat5 Vs Cat6

One space that’s typically ignored when trying to buy Class networking cables is the bodily dimensions they arrive outfitted with. Because the Cat6 cable has a barely completely different inner design – using barely thicker copper – it’s naturally thicker than the Cat5 cable. While this isn’t usually too problematic, there are particular eventualities the place this might make the cable unsuitable in your wants.

We should additionally take cable size into consideration too. There are some delicate variations to be discovered when evaluating the utmost size of every cable. Cat5 and Cat6 can each run as much as 100m – nonetheless, when using higher speeds, Cat6 cables are restricted to 55 meters as a substitute.

Which Class Cable For My Enterprise?

Selecting which Cat cable to make use of for your small business is massively vital – and for plenty of causes. It isn’t all about velocity – there are different components that ought to come into your choice, reminiscent of crosstalk interference and pricing.

That being mentioned, velocity is the very first thing that involves thoughts when selecting the Class cable that’s proper in your wants. Proper now, chances are high you’ll be utilizing some type of Cat cable to attach your self or your small business to the web. For those who’re pleased with that velocity, chances are high, you received’t have to improve – Cat 5 is sufficient. That being mentioned, if the web velocity is massively vital – you’re employed at a gaming firm or one thing – you would possibly need to contemplate checking your cables and upgrading them to Cat 6. The extra bandwidth of the Cat 6 cable, alongside elevated speeds, makes it many companies’ first selection.

That being mentioned, many companies at the moment are using the Cloud in immediately’s day and age – placing much less and fewer stress on the standard of your networking cables. By way of reliability, the Cat 5 cable has been doing a wonderful job for nearly 20 years now – offering environment friendly efficiency the place you want it.

Let’s no neglect concerning the value both. As you most likely guessed, Class 6 cables are dearer than Cat 5 – including one other annoying layer to the puzzle. Interference can also be one thing customers want to determine when buying Cat networking cables, with Class 6 offering essentially the most steady format. Class 6 cables even embody a nylon spline which helps get rid of crosstalk issues.

Which Class Cable For House Use?

However what about residence use? Effectively, for many common customers, utilizing a Cat 5 cable at house is greater than sufficient. Let’s not neglect, the Cat 5 was thought-about the gold customary for networking cables for nearly 20 years. There’s nothing to counsel that you simply’ll want something extra highly effective than that.

That mentioned, if you’re available in the market for one thing a little bit extra environment friendly, the Cat 6 cable will definitely present this.

Ultimate Ideas

So, there you might have it, our complete information to Cat 5 vs Cat 6 networking cables. Hopefully, this informative information has made selecting your subsequent community cable a little bit bit simpler.

On the finish of the day, all of it comes right down to your wants and necessities. Let’s be trustworthy, Cat 6 is by far the superior cable in the case of networking. Nevertheless, with the elevated price ticket it comes outfitted with, many will discover Cat 6 merely overpriced for what it gives. Compared, Cat 5 is a staple of the networking cable recreation, providing residence customers greater than sufficient theoretical juice to get essentially the most out of their web speeds. Nevertheless, with slower speeds and fewer bandwidth – to not point out extra crosstalk interference – some people might need to spend that little bit further on one thing extra outfitted for the job.
