Abstract:
An optical package comprising:an input ferrule comprising at least one capillary extending axially through said ferrule; at least two pair of optical fibers extending through said at least one capillary, said fibers comprising a first input fiber, a first reflected fiber, a second input fiber and a second reflected fiber, said fibers screened for a pre-determined tolerance for a characteristic selected from the group consisting of core concentricity, ovality, and diameter, wherein the pre-determined tolerance for ovality is equal to or less than about 0.8 percent; and an optical filter optically aligned with said optical fibers such that a first wavelength of optical signals transmitted through said first input fiber are reflected by said filter to said first reflected fiber and a second wavelength of optical signals transmitted through said second input fiber are reflected by said filter to said second reflected fiber.
