ABSTRACT:
A glass optical reflective tap is described that optically connects two optical fibers and may tap a portion of the light that is being communicated between the optical fibers. In one embodiment of the invention, the optical filter includes two D-lenses that operate as focusing or collimator lenses. The first D-lens focuses an optical signal onto a tap filter that allows a majority of the light within an optical signal to pass and also reflects a small portion of optical signal light to a reflective port. The second D-lens focuses the passed light into a transmission port of an optical fiber.
