While I have read that there is a 328 feet or 100 meter max when connecting from one switch to a device (PoE). However, my question is this. If I have a Cat 6 or Cat 6a direct connect ethernet cable that runs 372' from one switch to another switch and I have constant traffic coming and going from both switches. Am I still limited to the rules of 328' feet. Since technically, each switch if I am correct and not doing any POE devices should have 328' reach? Should I not have a max reach of 656' feet? Not saying I want to try that. But, right now I am running a 372' switch to switch and not having any drops, connection issues or latency.
Next question since I am not having any issues. What might be the possible downfalls going beyond the "so called" 328' max? other than the 500 nanosecond delay (latency) for every 3 feet beyond 328' which to me is nominal or not even going to bother me.
I am not a schooled network engineer, I am a hands on database guy, but I dabble in networking. So, In layman's terms. Can someone tell me what my possible pitfalls are if any?
The maximum distance for Ethernet cable runs is typically limited by the signal attenuation and crosstalk caused by the cable itself, and not by any limit imposed by the switch. The distance limits for Ethernet cables are typically around 100 meters (328 feet) for standard Cat5e or Cat6 cables. However, newer cables such as Cat6a and Cat7 are designed to reduce attenuation and crosstalk, and therefore can support longer cable runs.
In your case, you mention that you are using a Cat6 or Cat6a cable that runs for 372 feet between two switches and you are not experiencing any issues such as drops, connection issues, or latency. This suggests that your cable is working well within its specifications, and you are not experiencing any signal degradation that would cause problems.
It's worth noting that the 328 feet (100 meter) max distance is the standard distance limit set by IEEE 802.3ab. If you are using a switch that supports POE (Power over Ethernet) it should be noted that the distance limit for a POE device will be less than 100 meters.
As for the possible downfalls of going beyond the 328 feet max, the main concern would be signal attenuation and crosstalk caused by the cable, which can result in errors and reduced signal quality. Additionally, as you mention, there may be a slight increase in latency for signals traveling greater distances, but this is likely to be negligible for most applications.
- So in general for business networking , only use supported lengths only for the per cable category ,
