How can I detect CAT5 cable
How can I see if my LAN-Cable is CAT5 ?|
Is it a must that "CAT5" is written on the cable, or could it be that it is a Cat5 Cable and something else is written on it ?

It is at least reasonable to put a label like 'Category 5' or 'Cat 5' or 'CAT V' on a cable that's made up to Category 5 specs.
Sometimes they put "Class D" (as per international standard ISO/IEC 11801) if they want to emphasize that they target international markets. But the cable is essentially the same.
However, that's not it. I would advise you to look for some other marks like 'UL Verified' or 'ETL Verified' to be sure you have a good product in hands.
There are also other labels that matter.
For example 'CM' means Communications Multipurpose so you know you cannot run this cable in plenums. Run 'CMP' instead.
There are also some vendor-specific labels that can tell you bits of interesting information, but they usually have nothing to do with Categories.
If you can send me the label to firstname.lastname@example.org, I'll be able to tell you more.
