My thought was, if I have a splice enclosure 4200' down the line, I'll go down to row 42 and enter "Splice enclosure on pole 305". Then I can note on each fiber whether it passes through the enclosure, or note what it splices to, including a reference to another file if necessary. I understand they used to do something similar with 3-ring binders for mapping the pairs on phone lines. The first question I ran into was which distance do I go by: The actual distance the line has traveled The cable length, which will be ~15-20% longer due to slack loops The fiber length, which will be longer still due to the built in twist.but is easily measurable with an OTDR. All three somehow? Is this even a smart method? Plan B is to use GIS.

Re: [AFMUG] Cable documentation
See if you can open this: https://drive.google.com/open?id=0B-W9J8tPanuAeU1Lc3BDYWlVSjg Very rudimentary. But you can see that some of the strands on the cable go clear to the end. Other strands are cut at a hand hole and spliced to another cable. The other cable is shown at the far right. The >< symbols show it is spliced to a different cable. You connect the > to the < as you jump over handholes that are not part of the circuit for that strand. The – is a splice. The 0 or dot is the end termination. I used to have lots of color coding etc. I could not find any of the old copper cable books for an example so I hacked this example out.

Re: [AFMUG] Cable documentation
Yeah, been doing cable books for almost 40 years. There used to be a nice product from suttle press. Big cardstock pages, metal binder, metal hinges pressed into the pages. It would open up in a 4x4 orientation and each page was probably 11x17 so the whole book was 22x34 when fully open. You used a #5 pencil and wrote very light. You would erase when someone moved out and the pair was available. Nothing more than a cardstock spreadsheet with pre-printed fields. Made to last forever. On the columns, you put a name for the handhole or splice point at the top. Then if a cable is spliced into it mid way, you put a symbol in the cell showing it is cut and spliced to another route there. Then either at the end of the strand you can start up with the side route or you can put the side route on a separate sheet or tab. I will see if I can find an example.

Re: [AFMUG] Cable documentation
They twist the buffer tubes around each other in a loose tube cable. It's so when you make a coil you're not putting all the stress on the fibers on the outside of the coil, but rather it's spread evenly.
