So my question is this and I'm sure I know the answer. How often do I need to replace ethernet patch cables (Current cables have been in the patch bay for 10 years maybe longer) ? Is there a shelf life on them? Would adding a cat 6a Patch cable help me with a patch bay that is Cat 5e rated? In an office environment that uses 1gbps internal switches with a coax connection of 600mbps would cat 6a help? In the end with the current setup would it be worth the time and money to start upgrading or wait? Would not mind a video explaining this along with maybe some graphics.
