Hello sam.nowak41 and welcome to the Forum.
If you are looking at our catalog the only option that comes to mind single mode OTDR is 930XC-20M. Accuracy of the unit is ±(1m + 5 X .00001 x distance + sampling space) or in excess of ±1.005m in your case of 100+m. Note that I was not able to find a unit with mm or sub mm accuracy.
The cable you select should correlate to the connector you need. See our stock of fiber optic cable in the single mode.
