摘要： A ferrule and an associated fabrication method are provided that facilitates fiber-to-fiber contact without requiring the end portions of the optical fibers to protrude beyond the front face of the ferrule. The ferrule includes a ferrule body having opposed front and rear faces and defining at least one optical fiber bore extending between the front and rear faces and adapted to receive an optical fiber. Advantageously, at least the medial portion of the front face through which the optical fiber bores open protrudes outwardly beyond at least some peripheral portions of the front face. By designing the front face such that the medial portion protrudes outwardly beyond peripheral portions of the front face, angular errors in the peripheral portions of the front face and dirt or other particles that accumulate on the peripheral portions of the front face will not prevent the medial portions of the front faces of a pair of ferrules from making contacting as the respective fiber optic connectors are mated. As such, the end portions of the optical fibers need not protrude much, if any, beyond the front face of the ferrule in order to establish fiber-to-fiber contact such that the ferrule can absorb at least some of the forces that would otherwise be imparted to the optical fibers.

摘要： A splice housing assembly and an associated assembly method are provided in which the ferrule is mechanically decoupled from the splice body such that the ferrule has at least limited movement, typically in an off-axis direction, relative to the splice body. For example, the ferrule can be mechanically decoupled from the splice body by spacing the ferrule in a lengthwise direction from the splice body such that a medial portion of the first optical fiber extends between the ferrule and the splice body.

摘要： An adjustable tether assembly for a fiber optic distribution cable includes a tether cable and an overmolded housing secured at the end of the tether cable having at least one connector port. The tether assembly is attached to the distribution cable such that the position of the connector port is adjustable along the length of the distribution cable for mitigating differences between the pre-engineered span length distance and the actual span length distance following installation of the distribution cable. A method for mitigating a span length measurement difference in a pre-engineered fiber optic communications network is provided that includes optically connecting an adjustable tether assembly at a mid-span access location of a fiber optic distribution cable and positioning a housing secured at the free end of a tether cable having at least one connector port at a desired location in the network to compensate for the span length measurement difference.

摘要： A splicing connector and an associated splice mechanism are provided to splice first and second pluralities of optical fibers without buckling the optical fibers. The connector includes a housing and a retainer disposed of at least partially within the housing which defines a channel through which a plurality of optical fibers extend. The connector also includes a clip for securing the optical fibers within the retainer such that the end portions of the optical fibers are exposed through the forward end of the housing in preparation for splicing the optical fibers. Further, the connector includes a spring for urging the retainer and the optical fibers secured within the retainer toward the forward end of the housing, thereby permitting the optical fibers to be spliced without buckling the optical fibers.
