Cat5, Cat6, and Cat6a: Is it Time to Start Future-Proofing?

According to Primex, integrators should encourage commercial clients to consider the possible costs of delaying upgrading to Cat6a.

For most of the past few decades, new Ethernet installations have been dominated by Cat5, Cat5e, and Cat6 cabling. Cat5 saw its stock rise in the mid-to-late 90s, Cat5e had its heyday in the 2000s, and Cat6 has been a popular choice for the last ten years or so. But a new standard is emerging—Cat6a—and it’s causing many telecom specialists to factor in the value of “futureproofing” their upcoming projects.

Remember that by upgrading the Category cabling in a network, bandwidth and speed improvements will only be attained if all cabling and accessories are up to the minimum standard set out by the IEEE.

So, to help you decide whether Cat6a is the right choice for your next installation, let’s briefly dig into the high-level details of each standard.

Cat5 vs. Cat5e vs. Cat6

Cat5 was first introduced in the mid-90s and grew in popularity toward the late 90s. It’s rated for a maximum frequency of 100 MHz and top speeds of 100 Mbps. While it is still commonly used for local area networks, it’s too slow for most other applications and is now on its way to obsolescence.

Cat5e was introduced around 2000 and, as its name suggests, served as an “enhanced” version of Cat5. It offered the same bandwidth (100 MHz) but was designed to reduce crosstalk and handle speeds up to 1,000 Mbps, making it the first Cat standard capable of supporting the dream of Gigabit Ethernet.

Cat6 was introduced in the early 2000s but started becoming popular around 2008. Today, it’s considered the minimum standard for new installations and is backward compatible with Cat5, Cat5e, and even Cat3.

It offers a bandwidth of 250 MHz and supports speeds up to 10 Gbps and can come in a shielded option.

Cat6a: The New standard?

It’s early days still for Cat6a, but it’s growing in popularity in sectors like healthcare and education.

It offers several advantages over Cat6, including higher bandwidth (500 MHz) and 10-gigabit speeds over 330 feet of cable (as opposed to Cat6, which offers 10-gigabit speeds over 110-165 feet of cable).

Cat6a is also better equipped than the rest of the Categories to handle Power over Ethernet (PoE) connections, which are growing in popularity among next-generation devices.

Because Cat6a uses larger gauge cabling, it reduces power waste due to increased temperature in the cabling. Cat5e cabling, for example, has been shown to lose as much as 20% of power that’s delivered through the cable.

Is it time to futureproof with Cat6a?
 

Looking back, we can see that widespread adoption of each new Category standard was slow and delayed. Until the demand for higher bandwidth and speeds were needed for new devices and technology, older Cat standards were retained. Today and tomorrow, you or your clients may not have that luxury.

When advising your clients on structured wiring options, encourage them to consider the possible costs of delaying upgrading to Cat6a. How much will it cost to replace Cat5e or Cat6 with Cat6a in a few years? How much is their business expected to grow over the next 5, 10, or 20 years? How many more users do they expect to join their network?

When you consider the ever-increasing demands of our digital landscape, it’s not difficult to imagine a future 5 or 10 years from now in which Cat6a infrastructure is not only helpful to a business’ bottom line, but also essential.

@PHAND matrix switchers, in addition to being a cool party trick, are particularly useful when you need to deal with:

- An expensive source (e.g. Kscape)
- An exclusive source (e.g. office computer, game console, optical disc player)
- A requirement for AV synchronization (e.g. open floor plan with multiple TVs visible/audible to the user playing the same content
- Licensing/capacity issues (e.g. can only have X amount of media players associated to an account)

@PHAND I sure sell a lot of matrix switches to installers for there to be no demand for centralized video distribution…just because YOU aren’t selling it, doesn’t mean there isn’t still demand.

Agree with John.  Fiber is the way to go.  It’s also considerably cheaper than cat6a and is easier to terminate and manage in patch bays etc.  No question you should future proof but if it’s even a question just pull OM3 Multimode Duplex along with your cat6 and call it a day.

With the preferred method of delivery moving to streaming I’m seeing no advantage for HDMI 2.1 and its 48Gbps bandwidth. Your source these days is a little box with an app on it or an app built into a TV. Centralized video sources and distribution is being negated by the ability to bury that little streaming box behind the TV and run the cable companies app on it. Get cat5/6/6a to that box. Will we need 10Gbps capable cable in the future? Sure, but it’s not going to be for HDMI. We are removing BluRay players and cable boxes from system upgrades now and just replacing them with AppleTV/Roku for full surround systems, or just use the app built into the TV and a soundbar for smaller room systems.  Now that is not to say not to run fibre to locations. Fibre is going to come in handy for high bandwidth distribution of data sometime in the future.. but again not HDMI.

The PoE argument is the best one for using Cat6a…but if you are REALLY future-proofing, you should be running fiber along with your copper wire!  Cat6a or even Cat 7 is not going to handle the 48Gbps that HDMI 2.1 requires.  Fiber will.
