摘要： A foldable extension enclosure for a utility enclosure, each having first, second, third, and fourth sides connected by hinges and each folding only in one direction by means of detents on the sides. A first end of the first side slidably overlaps a second opposite end of the third side and a first end of the second side slidably overlaps a second opposite end of the fourth side. There is an internal top ledge on each side in an interior near a top end of the extension enclosure and the utility enclosure and an external bottom ledge on each side on an exterior near a bottom end of the extension enclosure, to mount the extension enclosure to the utility enclosure with concave and convex detents. Convex detents are at the top end of the utility and extension enclosures and concave detents are at the bottom end of the extension enclosure. The convex detents also reversibly lock a lid to the tops of the utility and extension enclosures.

摘要： A cable assembly includes a cable and a cable mounting clamp. The cable mounting clamp includes a base removably connectable to a surface. The base includes an outer body which defines an inner channel and a support ramp disposed within the inner channel, the inner channel extending along a longitudinal axis. The cable mounting clamp further includes a roller tube disposed within the inner channel and moveably mounted on the support ramp, the roller tube translatable along the longitudinal axis relative to the support ramp. The cable is inserted through the roller tube and extends through the inner channel, such that the cable is translatable with the roller tube along the longitudinal axis.

摘要： Control systems and methods for aligning multimode optical fibers are provided. A method includes producing a brightness profile for a first and second multimode optical fiber. The method further includes determining a cladding center position and a core center position from the brightness profile of the first multimode optical fiber and from the brightness profile of the second multimode optical fiber. The method further includes calculating a concentricity error for the first multimode optical fiber based on the cladding center position and the core center position from the brightness profile of the first multimode optical fiber and for the second multimode optical fiber based on the cladding center position and the core center position from the brightness profile of the second multimode optical fiber. The method further includes aligning the first multimode optical fiber and the second multimode optical fiber based on the concentricity errors of the first multimode optical fiber and second multimode optical fiber.

摘要： A method of testing an optical network with an optical time-domain reflectometer includes determining a reference power of the optical time-domain reflectometer based on a power level of a reflected light pulse reflected from an optical reflector. After determining the reference power, the method includes connecting the optical time-domain reflectometer to one end of the optical network and connecting the optical reflector to an opposite end of the optical network. The method also includes determining a return power through the optical network based on a power level of a reflected light pulse reflected through the optical network from the optical reflector to the optical time-domain reflectometer. The method further includes determining a loss of the optical network based on the reference power and the return power.

摘要： Optical fiber adapters and connectors are provided. An optical fiber adapter includes an adapter body, the adapter body extending along a longitudinal axis between a first end and a second end and comprising a first adapter portion which includes the first end and a second adapter portion which includes the second end. Each of the first adapter portion and the second adapter portion is one of a male adapter portion or a female adapter portion. The optical fiber adapter further includes a ferrule disposed within the adapter body, the ferrule extending along the longitudinal axis between a first end and a second end, and a thin-film filter provided on one of the first end or the second end of the ferrule, wherein the thin-film filter limits the wavelengths of light transmitted therethrough to within a predetermined wavelength range.
