Black Box Explains...CAT5: When more isnt always better..
In data communications applications, using products that exceed required capacities is usually not a problem. For example, if a 28.8K modem is required, a 33.6K or 56K model will work just fine.
But sometimes, more isnt better. Take KVM extenders designed to expect CAT5 and only CAT5 cable. Youd expect that Category 3 cable wouldnt be effective with these products, and you would be right.
But you may also assume that if Category 5 cable works fine, Category 5e, Category 6, and other higher-capacity cables would work even better. Unfortunately, this isnt the case, and heres why:
KVM extenders from many manufacturers, including ServSwitch CAT5 KVM Extenders, are designed specifically for the Category 5 specs defined by the TIA/EIA standard. Higher-level cables, such as Category 5e, have different characteristics and specifications. Although differences—specifically twist ratios—might seem small, they can have a negative impact on these extenders, which are expecting a true Category 5 transmission.
So with ServSwitch CAT5 KVM Extenders, you can think big with CAT5—just dont think bigger.
