An installation method in which a blowing machine feeds cable into a microduct while compressed air flowing alongside creates drag that carries it forward with very little tension. Runs of 1 to 3 km in one shot are common with microcable, and extra fiber can be blown in later or swapped out without opening the pathway. It depends on clean, continuous, pressure-tested duct.
Duct passed the air test, so the blowing crew can jet the 144 microcable to the next vault this afternoon.
