I'm hoping someone here ha some experience pulling cable. Seemed like the best place to ask a question like this compared to other subs.
I work for a commercial structured cabling contractor building out the MDFs and horizontal runs. There are two main philosophy's for labeling the cables when they are getting pulled. One is to label them with final labels. That is, if you have 500 drops, and the format is gonna be something like IDF01-01-B46, that's the label you wrap around the cable when its pulled. The other way is to make temp labels like 001 through 500 and then make a cut-sheet and 'convert' the temp labels to permanent ones at the end like in the previous example.
Group 1 people think its more efficient because you are only having to label it once. Group 2 people think Group 1 creates a lot of problems when anything goes not according to plan (moves, add, changes, damaged cables that need to be re-pulled, etc). Because the final label was applied before everything was finished, it can cause the final labeling to be out of sync in certain rooms or areas. Whereas if you just use temp labels and a cut-sheet, you can adjust the final labels to accommodate the as-built status and it doesn't have any anomalies.
Then there are the people that don't label anything when its getting pulled and just bundle it as it comes into the IDF and then tone and label everything after the fact which usually isn't an option for the type of clients we deal with but may be acceptable for small businesses with a couple dozen runs.
If anyone has done cabling for large projects I would like to hear what you think the best practice is and why. Ive done both systems and have seen the flaws in each, but I'm guessing one's probably better than the other, I just don't know how to determine it. My current boss is a firm believer in using final labels as you go.
