Deploying fiber optic cable from the outdoors into a building interior can be time consuming and requires extensive interconnecting hardware when ordinary approaches are used. National Electric Code (NEC) Article 770.48 requires that unlisted, outside plant (OSP) fiber optic cables be terminated within 50 feet of a building entrance.1 Entrance is defined as the point at which a cable emerges from an external wall, a concrete floor slab or a rigid metal conduit (Type RMC) into the building.2 This limitation requires that a building entrance terminal be installed and the OSP cable spliced to a suitable NEC flame-rated cable. The cable is then deployed to locations inside the building as needed. Cable solutions that can eliminate the need for the entrance terminal and associated splicing can help to significantly reduce installed costs and enable faster installation.|Deploying fiber optic cable from the outdoors into a building interior can be time consuming and requires extensive interconnecting hardware when ordinary approaches are used.
