Abstract
It is disclosed a method for coupling an optical fiber to a fiber optic cable, the fiber optic cable comprising a sheath surrounding an optical core comprising a buffer tube, the optical fiber being loosely contained in the buffer tube. The method comprises: cutting the sheath for a predetermined length thereof and exposing a corresponding portion of the optical core extending outward beyond a butt of the cut sheath; cutting the buffer tube of the exposed optical core and exposing a portion of the optical fiber; using a blocking tube to at least partially surround a section of the exposed portion of the optical fiber; and injecting a sealant into the blocking tube to lock the optical fiber within the blocking tube and couple the optical fiber to the fiber optic cable.
