A combined multiplexer/demultiplexer for use in optical communication systems is disclosed. The combined multiplexer/demultiplexer includes a plurality of waveguide arrays and a plurality of signal carriers, each disposed substantially symmetrically about an optical axis of the device. In operation, a signal carrier emits a multiple wavelength optical signal that is received and directed to a dispersion apparatus by a light focusing device. The dispersion apparatus diffracts the optical signal into selected spectral components and reflects the spectral components back to the waveguide arrays through the light focusing device. The signal processing, such as multiplexing and demultiplexing, performed by each waveguide array depends on their configuration. The waveguide arrays may be configured to substantially simultaneously multiplex and/or demultiplex the spectral components.

A diffractive optics system for wavelength division multiplexing and demultiplexing optical signals. The present system can be employed in multiplexers, demultiplexers, spectrum analyzers, and the like. In one embodiment, the diffractive optics system includes a waveguide array, a lens assembly, first and second diffractive optical elements (“DOEs”), and a reflector. In a demultiplexing operation, a multiplexed optical signal is input into the system via an input waveguide in the waveguide array. The signal is focused by the lens assembly, then transmitted through the first and second DOEs, where diffraction of the signal and separation of its constituent wavelength-distinct channels occurs. The channels are then reflected by the reflector back through the first and second DOEs, after which each channel is directed by the lens assembly to one of a plurality of output waveguides located in the waveguide array. A conversely similar process is followed for producing a multiplexed optical signal.

A fiber optic connector endface inspection probe includes a microscope system, a camera module, and an image processing system. While the objective lens of the microscope system is being moved towards and past the focused position for the endface of a mated connector, either by manually turning a focusing knob in one direction or via an automatic transmission mechanism, the camera module continuously takes and sends endface images to the image processing system, wherein a microprocessor continuously monitors the sharpness of the endface images to acquire a focused image and analyze it to make an endface inspection pass/fail judgment, without using an external display to monitor the endface images. The microprocessor further comprises an embedded web browser for converting endface images and inspection report into web pages to be transmitted by a wireless transmitter of the image processing system to external devices for optional monitoring or manual inspection.
