What is the most effective solution you used to label cables?

Yes i know there are a lot of howtos and already answered questions about this topic, like this one: How do you organise the cables in your racks?

Currently i am searching the web for different techniques (alternatives) for labeling the cables at the server racks and/or data centers. Unfortunately i do not have any experience with labeling/documentation of network cables in a large scale.

As far as I could lookup by now the current labeling techniques are coloring and a self defined print-labeling technique (numbering, text) maybe also according to a standard which are usually used.

I want to know if QR, RFID (ok RFID in a data center would be stupid due to the radio frequency wouldn't it be?), Barcodes or similar (??) have already been used by some administrators or why they did not consider such techniques at all? Too complicated (with QR scanner etc..) if you are in front of the cables and want to get quick feedback for what the cable is?

What alternatives are out there? Advantages/Disadvantages? Best-Practice?

I would appreciate any help on this topic, thank you!
