A wavelength division multiplexing device includes an alignment substrate configured to provide alignment between optical components of the device. The device includes a plurality of collimating lenses, and the alignment substrate includes a plurality of aligners. Each of the aligners is configured to place a respective one of collimating lenses in a predetermined position and a predetermined orientation with respect to the other collimating lenses. The alignment substrate thereby provides passive alignment of the collimating lenses with a designed optical path. The substrate may also include visual alignment markings that provide an indication of the placement of multi-layer thin film filters so that the filters define an actual optical path in alignment with the designed optical path, and integrated optical waveguides that provide an optical beam to each of the collimating lenses.

Field-configurable optical devices and methods are disclosed. In one example, a field-configurable optical device includes a housing defining an enclosure, an input port located at the housing, a pass-through port located at the housing, a plurality of output ports located at the housing, a splitter disposed within the enclosure, a plurality of couplers within the enclosure, each coupler including an input, a first output, and a second output. Each coupler has a power splitting ratio between the first output and the second output that is different from the other couplers. An input port fiber optic jumper assembly within the enclosure. A pass-through port fiber optic jumper assembly is within the enclosure. Moving the input port fiber optic jumper assembly and the pass-through port fiber optic jumper assembly from a first coupler to a second coupler of the plurality of couplers changes the power splitting ratio of the field-configurable optical device.

A wavelength division multiplexing device includes a common port and a plurality of filters that define an optical path. The common port includes a collimator that transmits an optical beam including a plurality of optical signals. Each optical signal is associated with a different wavelength range, and each filter includes an interface having a radius of curvature. One filter is configured to receive the optical beam from the collimator, transmit an optical signal through its interface, and reflect the remaining portion of the optical beam toward another filter. The common collimator and filter are configured so that the reflected portion of the optical beam has a beam waist located in the optical path midway between the filters, and a wavefront radius of curvature at the other filter that matches the filter radius of curvature of that filter. A method of processing light in such a device is also disclosed.

A spray nozzle, systems and methods for cleaning at least one optical fiber end face of an optical fiber connector. The nozzle includes a housing body with a first end portion and a second end portion. A discharge passage carries an atomized mixture of cleaning fluid and positively pressurized air from the first end portion to a discharge opening at the second end portion.
