As of 5/31/2024

Question: How many strands of fiber are being Blown in?

Answer:

Depends: Per PWS para 3.1.5, if able to clear obstruction, one strand would be removed from its current position and that strand would be blown in to the now-unobstructed path. If unable to clear obstruction, per PWS para 3.1.6, 5 ea. strands would need to be removed, a new BOF cable needs to be installed, then 5 ea. strands blown in to the new BOF cable.

Question: Fusion splicing / light duty connectors?

Answer:

Per PWS para 3.1.4, the run goes from a FIB to a FIB, so fiber will need to be spliced at each end.
