So, check out our best Ethernet cable reviews. Or you can go down the more basic, budget route, and see for yourself what's a  CAT5 compared to CAT6 like.

What's Better Cat 7 Or Cat 8?

The differences between Cat 7 vs cat 8 ethernet cables are quite small, but are still useful to understand and consider when choosing the right ethernet cable to access the Internet with your device. It will help to learn first what a CAT 6 or a CAT 6A cable brings to the table here, or find out how CAT6 compares to CAT 6E.

The maximum length of Cat7 cables is 100 meters with up to 10 Gbps in speed.  In comparison, the maximum length of Cat8 cables is limited to 30 meters with up to 25 Gbps or 40 Gbps in speed.

Both Cat7 and Cat8 ethernet cables offer shielding cable constructions that provide extensive shielding designed for reduced attenuation and higher performance for high speed ethernet communication connection.  When comparing cat7 vs cat8 cables, other specifications should be considered like cabling length, speed frequency, connectors, and backward compatible functionality.

When comparing previous versions of lower category cables like Cat5 and Cat6 cables, we can see that the cat7 vs cat8 cable offers generally a higher speed of 600 MHz to 2000 MHz.

Another major difference between cat7 vs cat8 cables is the number and types of connectors that may be backwards compatible with previous lower category cables.  The Cat7, short for Category 7, cables normally have longer cables than the Cat8 cables.

When comparing between cat7 vs cat8, another important advantage to consider is the connection speed and distance.  The lower category Cat6 cable tops off at 250 Mhz, but the Cat7 and Cat8 cables both use a higher speed frequency to support even higher data transmission rates.

Cat7 can reach frequency speeds of up to 600 Mhz for a range of 100m. On the other hand, Cat8 can reach up to 2000 MHz at up to 30 meters, which is a much shorter range less than 100m in comparison to Cat7.

If you decide to use Category 7 or Category 8 cables, remember that the main differences in cat7 vs cat8 come down to the cabling length, frequency, speed or other specifications.  However, it depends on what your home or business office network may need, so price or other specifications may also even be a limiting constraint when deciding which cable to get.

Is Cat 8 The Best Ethernet Cable?

The Cat8 ethernet cable is the fastest cable yet.  It has data transfer speeds of up to 40 Gbps (gigabytes) which is four times faster than the Cat6a cable.  The Cat8 cable also supports bandwidth of up to GHz (gigahertz), which is also four times more than the standard bandwidth supported with the Cat6a cable.

These key added features and better support make the Cat8 cable type superior for reducing latency and increasing signal quality. Check out here the best Ethernet cable for gaming reviews, or more specifically, the best Ethernet cable for gaming on PS4.

Are Cat 8 Cables Worth It?

The Cat8, short for Category 8, ethernet cable costs a bit more than the cat6 and cat7 cables because of its higher performance.  The higher price of the cat8 cable comes down to the wiring in its twisted pair cable structure and shielding.

Because higher frequencies require more twists in the cable twisted pair, the process of manufacturing such cable pairs becomes more expensive.  The cost of raw materials for shielding gets more expensive as well.

As more twisting occurs on the Cat8 ethernet cable, the more increasingly difficult it is to shield higher frequencies from interference and crosstalk.

Should I Use Cat 7 Cable?

The Cat7, short for Category 7, Gigabit Ethernet cable may be considered a more expensive option, but that comes with some benefits.  The Cat7 cable is generally the most durable and have a longer lifespan than the Cat5 or Cat6 cables.  Therefore, many critics feel that the greater return on investment from the Cat7 cable is an appealing feature of this cable.

Unlike many other cables , the Cat7 cable does not use the traditional RJ-45 Ethernet header (also, technically known as an 8P8C connector).  Instead, the GG45 connector is used.

The GG45 connector is a proprietary connector that is backward compatible with RJ 45.  These connectors are a little more difficult to find.  However, the Cat7 cable is also compatible with the TERA connector, which is another connector type that is not commonly used in industry.

Despite these drawbacks, the Cat7 cable supports high speed ethernet communication and is fully shielded to the S/FTP standard, where not only does it have an overall braided shield, but also each individual twisted pair is foil shielded as well.

Because Cat7 cables were not designed to confirm with the common industry standard for cables,  the popularity of the Cat7 cable quickly declined and led to the development of the Cat6A cable in 2008.

It is important to note that the Cat6A is actually a newer iteration of the cable wiring than the Cat7, so this further leads to some confusion in the marketing and promotion of this new cable  because of the higher number category for the Cat7 cable than the Cat6 cable.

A disadvantage of the Cat7 cable is that the cable  lacks the official stamp of approval and certification from the Institute of Electrical and Electronics Engineers (IEEE) as well as from the Electronics Industries Alliance (EIA).  This is a driving factor for the low popularity of Cat7 cable for many adopters who would prefer some of the cable types be officially certified as an industry and professional standard.

Cat 7 vs Cat 8 Cables: What's the Difference?

When choosing between Cat7 vs Cat8 data cables, it is important to compare and contrast the features and capabilities of both types of cables before making an informed decision for your data and Internet needs.

Let's take a look at the major differences of their features and functionality of cat7 and cat8 cables for comparison.

Pricing

The Cat8 cable is a newer iteration of data cables with more expensive materials in the wiring.  Therefore, the Cat8 cable general cost more than the Cat7 cable because of its unique features.

Maximum Cabling Length

The maximum cabling length of the Cat7 cable is 100 meters and supports a maximum frequency speed communication  up to 10 Gbps.  The maximum cable length of the Cat8 cable is limited to only 30 meters with at least a speed of 25 Gbps or 40 Gbps.  Both cables offer decent shielded cabling length or your home or office needs compared to previous versions like the Cat 5 or Cat 6 cable that allows up to 100m in length.

Performance

Cat 7 cables support a speed of up to 600 MHz, whereas the Cat8 cable offers performance speed of up to 2000 MHz (2 GHz).  This speed frequency when comparing cat7 vs cat8 is still quite good in comparison to the lower category cat6, which only reaches a speed frequency of up to 250 MHz.

Connectors

The Cat7 cable provides a 4-connector channel with shielded cabling.  These cables require twisted wires in order to become a full shield system, also known as screen shielded twisted pair (SSTP) or screen foiled twisted pair (SFTP) wiring.  This eliminates alien crosstalk as well as improved noise resistance.  The connector type is non-RJ45.

The Cat7 cable also requires modern test equipment, so this may prove to be an additional cost when accounting for additional expenses for equipment, wires, and other applications during the testing phase.

The Cat8 cable provides a 2-connector channel.  Similar to the Cat7, the Cat8 cable requires shielded cabling.  Although the physical  appearance looks quite similar to lower category wires like the Cat 6 or Cat 7 cables, the major difference is that the Cat8 cable is backward compatible in its connector as it terminates in RJ45 connections for Class 1  or non-RJ45 connections for Class 2.

The Cat8 cable is compatible with the standard connectors of previous versions such as Cat7, but not compatible with Cat5e and Cat6 cables.

Conclusion

When deciding between cat7 vs cat8 as a cable network to get for your home or business office, there are many factors to consider.  Even with so many different categories of cables or wires, if your goal is to get connected to the Web and ensure high speed data transfer within the network, you should choose one that is fairly priced to your budget and meets your network needs that will be used on a daily basis.
