摘要： 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.

摘要： The invention provides a “floating” port assembly of a receptacle of a transceiver. The configuration allows the transmitter port assembly to float conically (e.g., angularly from side to side and up and down) relative to the axial direction of the receptacle sleeve inside of the receptacle when a mechanical load placed on an optical fiber cable connected to the receptacle is transferred to the sleeve of the port assembly. The port assembly has a spring-return mechanism that biases the assembly such that it returns to its original center position when the load is removed. This floating isolates the ferrule of the optical fiber cable and the sleeve of the receptacle from external loadings transmitted via the fiber optic cable. Isolating the ferrule and the sleeve from the external loading dramatically reduces the effects of these external wiggle loads on the optical performance of the transmitter of the transceiver.
