A fiber optic cable includes a core and a binder film surrounding the core. The core includes a central strength member and core elements, such as buffer tubes containing optical fibers, where the core elements are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the core elements. The binder film is in radial tension around the core such that the binder film opposes outwardly transverse deflection of the core elements.

A guide pin for mating multi-fiber optical ferrules includes a first end, a second end and a flexile feature adjacent to the second end. The first end has a first end width and the second end has a first engagement width and may change to a second engagement width while engaging a guide pin bore in a ferrule. The change in width permits the guide pin to engage and axially align with guide pin bores of varying diameters to achieve reliable optical mating of optical wave guides.

An optical fiber splitter has a higher density fiber optic array that allows for smaller packaging. The optical fibers that extend from the optical fiber splitter have one end connectorized and their spacing at the other end reduced, thereby eliminating components that were heretofore required. A method of making the fiber optic array includes interleaving the optical fibers to reduce the overall dimensions of the fiber optic array and the fiber optic splitter. A tool is used to reduce the spacing of the optical fibers in the fiber optic array.
