Middle-mile rebuild without missed windows
A regional ISP was rebuilding its middle-mile between three PoPs and needed 8 km of pre-terminated OS2 trunk with strict polarity and per-fiber test data — inside a two-week install window.
Custom OS2 MPO-12 trunks with Method B polarity, per-fiber IL/RL data attached to each serialized reel, and split-shipping so the first crew wasn't waiting on the last reel.
The trunk shipped on schedule, polarity was verified on install, and the team hit their cutover window with margin to spare.
“Every fiber came with test data taped to the reel. Our install crew didn't waste a single hour chasing a bad channel.”
