Abstract
By the present invention, a plurality of blown optical fiber insertions are made into a duct by employing the following method: first installing at least one fiber through the duct to a terminal; trapping the first fiber in place; and subsequently blowing at least one second fiber alongside the first trapped fiber through the duct to a terminal. In a preferred embodiment, a trap fitting is mounted onto an entry end of the duct to permit multiple insertions of blown optical fiber into a duct. The trap fitting comprises a fitting fixed into the duct downstream from a blow head; a passageway through a wall of the fitting; a cylindrical sleeve fixed to the exterior of the fitting over the passageway; and a plunger mounted in the cylindrical sleeve.
