Abstract
An optical network unit is associated with a multi-wavelength optical fiber communications system carrying low-power digital signals bidirectionally transmitted at a first and a second wavelength and a high-power analog video signal transmitted at a third wavelength. The unit comprises a housing having a connection for the optical fiber; and an optical filter, first and second optical units, and a beam splitter mounted in the housing. The optical filter is interposed between the fiber termination and the second optical unit, and is adapted to block light of the third wavelength but bidirectionally transmit light of the first and second wavelengths. The system is readily implemented, and any combination of the data and video services may be selected. A high level of skill is not required for changing the combination of services procured.
