摘要： An optical coupler for withdrawing light from an optical fiber includes first and second movable members on which are mounted a plurality of bending posts offset longitudinally relative to one another. A retaining post, offset longitudinally from the bending posts, has a groove therein so that an optical fiber can be wrapped therearound. Thereafter, the first and second members are moved towards each other such that the bending posts interleaf and bend the optical fiber in a plurality of positions causing light to be emitted from the optical fiber at bent portions thereof, which light is detected by optical detectors located behind the bending posts.

摘要： A method of forming a tap into an intermediate point on a continuous coaxial cable, and a coaxial cable tap housing suitable for forming such a tap. The tap housing includes a recess and an alignment element having a predetermined spatial relationship with the recess. The recess has an entry, an exit and a passage connecting the entry and exit. When the tap housing is fixed to a cable, the exit of the recess is closer to the outer conductor of the cable than the entry of the recess is to the outer conductor. The alignment element is used to position a cutting tool which is inserted through the entry of the recess to form an opening in the outer conductor and a cavity in the dielectric under the opening. A tap insert, which includes a coupler assembly, is mounted to the housing, and the coupler assembly is inserted through the entry of the recess and through the opening into the cavity formed in the cable. In specific embodiments, the recess and opening are elongated.

摘要： This invention provides a method and apparatus for making certain measurements across a splice of a first optical fiber and a second optical fiber, then calculating the actual decibel attenuation across the splice for optical signals transmitted through the fibers during actual use. The method of this invention involves measuring the optical power P.sub.2 in the second fiber with the fiber ends separated longitudinally a certain distance, then measuring the optical power P.sub.1 in the second fiber with the fiber ends positioned close together for effecting the splice. The attenuation is calculated from the formuladB=10 log(P.sub.1 /RP.sub.2)where R is a predetermined constant for the fibers being spliced.

摘要： An optical fiber water sensor includes a mandrel having a convex or concave shape adjacent to an optical fiber which is adjacent to a water swellable material held in a reservoir. Upon coming in contact with water, the material swells and deforms a section of the optical fiber about a contour defined by the mandrel thus attenuating a signal propagating through the fiber which is detected by an optical detector to indicate the presence of water.
