Can I use Cat 6 cable with Cat 5e jacks and patch panels?
For a system to be rated at Cat 6, all of the components in the system have to meet the Cat 6 standard. However, Cat 6 is fully backwards compatible with Cat 5e, so if the system's technical rating is of no concern to you, feel free to use all of the Cat 5e components you want.
Using Cat 6 cable with Cat 5e components is a great way to future proof your network if your budget is limited. Jacks and patch panels are relatively easy to switch out in the future if you leave enough slack in the cable that you can cut off the component ends and reterminate the runs. Cable is a bit tougher to change out once the walls are up.
