As a means of future proofing your network cat6 is generally a better choice and worth the small premium in price.
Cable rj45 cat 5e ou 6.
For example cat6 ez rj45 connectors from platinum tools use 0 275 inches as a maximum cable od which is plenty for a typical 0 205 diameter cat5e cable.
For these ez rj45 connectors individual insulated conductors must also be 0 041 inches or less to fit through the connector.
The cable standard specifies performance of up to 250 mhz compared to 100 mhz for cat 5 and cat 5e.
Many cat 6 cables also include a nylon spline which helps eliminate crosstalk.
The only thing you have to look out for is the crimper plug combination.
As the description implies a solid cable uses a single piece of copper for the electrical conductor within each wire of the cable whilst stranded wire uses a series of copper strands.
Cat5e and cat6 cables are both backwards.
If you have to use a cat cable with an rj45 connector in order to create a domestic network at your home cat5 type wires are quite enough.
Category 5 cable cat 5 is a twisted pair cable for computer networks since 2001 the variant commonly in use is the category 5e specification cat 5e the cable standard provides performance of up to 100 mhz and is suitable for most varieties of ethernet over twisted pair up to 1000base t gigabit ethernet.
Although the spline is not required in cat 5 cable some manufactures include it anyway.
Cat 6 has to meet more stringent specifications for crosstalk and system noise than cat 5 and cat 5e.
Cat6 connectors are designed for 24 and 23 awg conductor wire.
In cat 6 cable the spline is not required either as long as the cable tests according to the standard.
If you have used your current crimper plug combo to make working cables in the past it should still work with cat 5 cat 5e and cat 6.
In the picture above the cat 5e cable is the only one with a spline.
Cat6 cables also called category 6 or cat 6 cables provide lower crosstalk a higher signal to noise ratio and are suitable for 10gbase t 10 gigabit ethernet while cat5e cables support only up to 1000base t gigabit ethernet.
Cat 6 and cat 5e should work with either type.
The reason is cat6 cables come up with a better insulation to reduce crosstalk and other consequences that come up as a source of on the line noise in cable based networks.
