摘要： A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.

摘要： A fiber optic distribution cable assembly having at least one factory-prepared mid-span access location for accessing and terminating optical fibers of the distribution cable includes a tether containing at least one optical fiber optically connected to an optical fiber terminated from the distribution cable and an overmolded body encapsulating the distribution cable and a portion of the tether to form the mid-span access location. The mid-span access location is provided with a preferential bend along an axis that is common to the distribution cable and the tether by a strength member positioned within the overmolded body and/or the overmolded body having a geometrical configuration that promotes bending along the common axis. The preferential bend reduces any path length differences between terminated optical fibers routed substantially on the common axis and optical fibers remaining within the distribution cable induced by bending, thereby preventing breakage of the terminated optical fibers.

摘要： A fiber optic connector includes a multifiber ferrule and at least one force centering element for applying a biasing force to the ferrule in the longitudinal direction without introducing a moment about a lateral axis. The connector further includes a coil spring for exerting the biasing force and a spring seat disposed between the coil spring and the ferrule. The rearward portion or the forward portion of the spring seat may be provided with a pair of outwardly extending protrusions that are laterally spaced apart to transfer the biasing force to the ferrule. Alternatively, the forward portion of the spring seat or the rear face of the ferrule may define a convex surface. Alternatively, the ferrule defines a convex surface in the direction of a first lateral axis and the spring seat defines a convex surface in the direction of a second lateral axis perpendicular to the first lateral axis.

The fiber optic distribution cable includes at least one preterminated optical fiber withdrawn from a tubular body at the access location, a connector attached to the preterminated optical fiber, a transition piece for transitioning the preterminated optical fiber from the tubular body into a protective tube, and a protective shell encapsulating the access location for protecting the pre-connectorized optical fiber. Alternatively, the fiber optic distribution cable includes at least one preterminated optical fiber withdrawn from a tubular body, a transition piece for transitioning the preterminated optical fiber from the tubular body into a protective tube, a connector attached to the preterminated optical fiber, a plurality of cable centralizers, and a protective shell for encapsulating the access location and protecting the pre-connectorized optical fiber.
