InDuct FiberGlass

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.

All-dielectric design

InDuct FiberGlass is an all-dielectric and UV-resistant design which can have up to 864 fibers. Its maximum rated design tension can reach up to 607 lb and crush is 126 lb/in.

The cable consists of a stranded core with a central strength member (FRP), dry loose tubes with optical fibers and PE fillers (where applicable). The stranded core is fixed by water-swellable yarns. Fiberglass yarns are laid over the stranded core. Fiberglass yarns ensure a certain degree of protection against rodents making this InDuct design an anti-rodent fiber optic cable.

Typical application:

— It can be pulled into underground ducts and sewer pipes

— It can be installed along bridges, tunnels and other structures

— It can be installed into indoor/outdoor cable conduits and trays

— It can also be lashed

This fiberglass cable has a reduced weight and size, and it’s easy to install. Moreover, all Incab InDuct cables may be produced as flame-retardant.
