For Cat6:

  • It can handle more data than its predecessor and offers increased speeds up to 10Gbps (gigabits per second).
  • It also supports PoE (power over ethernet) which allows power to be delivered through the same cable as data transmission.

Both types of cabling are highly reliable when it comes to router compatibility, so either choice will provide you with an efficient networking solution that’s perfect for your needs. But cost should also be taken into consideration when selecting which type of cabling is right for you.


Considering cost, Cat6 cables may be more expensive than Cat5 cables, so choose wisely depending on your budget. However, the power consumption is lower and installation complexity is simplified, which could lead to long-term savings that outweigh the upfront costs associated with Cat6.

Durability of the cables is key for any cable purchase, so it’s important to factor in potential repairs or replacements that could occur over time when making a decision.


Cat6 cables are more durable than Cat5, so they’re less likely to fray or break under normal wear and tear. They have a higher-grade PVC jacket that is designed to last longer, as well as an improved internal design which allows for greater flexibility.

Here are some of the other benefits of Cat6 cables:

  • Noise immunity – The thicker shielding on Cat6 cables provides better protection against electromagnetic interference from external sources such as power lines or other network cables.
  • Interference resistance – The twisted pair design of Cat6 cables helps reduce crosstalk between wires, which can lead to interference with data signals travelling along the cable.
  • Higher bandwidth – With support for up to 10Gbps speeds, Cat6 enables faster data transfer than Cat5e and is suitable for applications such as streaming HD video or gaming.
  • Greater distance – As compared to 100 meters for Cat5e, the maximum length of a Cat 6 cable is 250 meters when used with Gigabit Ethernet networks.
  • Increased durability – The thicker insulation on each wire in a Cat6 cable increases its robustness and makes it less susceptible to damage during installation and use.

All these advantages make it clear why choosing a reliable, high-quality Category 6 cable can be beneficial in many situations where durability is a priority. This makes them ideal for long-term installations in commercial buildings or other areas prone to wear and tear over time. With their improved performance and longevity, they’re definitely worth considering when making your decision about what type of cable is right for you.
