  • Optical sub-assembly with electrically conductive paint, polymer or adhesive to reduce EMI or sensitivity to EMP or ESD
    Patent number: 7976226
    Abstract: Disclosed are various embodiments of an optical wavelength division demultiplexer or multiplexer sub-assembly configured to receive or transmit optical signals conveyed thereto or therefrom by a fiber optic cable. Selected portions of external surfaces of the sub-assembly are coated with an electrically conductive paint, polymer or adhesive to provide an EMI, EMP or ESD shield. Typically, the sub-assembly comprises an integrally molded plastic optical block and a separate integrally molded coupling module with a ferrule and fiber optic cable receptacle. In one embodiment, selected external surfaces of the optical block and coupling module are coated with a coating having a predetermined electrical conductivity to provide a desired degree of EMI, EMP or ESD shielding.
