Multi-Tube (MT) FiberGlass yarns

All-dielectric outside plant (OSP) cable is typically deployed in ducts. It can also be lashed to a messenger wire for aerial installation and can be attached to bridges or the lining inside a tunnel. The NESC permits OSP cable to be run up to 50 feet inside a building. Using fiberglass yarn lowers cost and provides a degree of rodent protection.
