An apparatus for providing optical wavelength selectivity that includes a housing; an optical transmitter in connection with the housing that delivers a beam of light; a light focusing arrangement located inside said housing and in alignment with the optical transmitter; an optical detector that receives the beam of light from the focusing arrangement; and a filter that allows a predetermined range of optical wavelengths to pass through to the optical detector. The apparatus combines multiple optical components into a single discrete TO-package for use in a high speed (Gigabit) optical communications network. |
