摘要： A device (70) for switching optical signal paths of the type utilizing a plurality of light-transmitting optical fibers (40, 50) comprises a flexible elongated sleeve (20) having a longitudinally continuous interior cross section (24) with a plurality of corners (30) forming fiber-aligning grooves. The sleeve loosely receives a first fiber (40) from a first sleeve end (26) and a plurality of second fibers (50) from a second sleeve end (28). Each second fiber has its coupling end biased against an assigned corner. Also, the ends of all the second fibers are contained in one transverse plane (23). The coupling end (46) of the first fiber adjacent the transverse plane and a portion (42) of the first fiber, remote from its end, is fixedly secured to the sleeve. Coupling of the first fiber with any of the second fibers is achieved by flexing the sleeve to move the first fiber end to the corner containing the selected second fiber.

摘要： In order to recoat bared end portions (32--32) of optical fibers (34--34) which have been spliced together, the spliced portions of the fibers and portions adjacent thereto are positioned in a groove (51) of a base plate (43) of a mold and enclosed with a cover (60). The cover is slidably moveable relative to the groove to allow an injection nozzle (81) which extends through the cover to become aligned with the fiber. Coating material (92) is introduced through the nozzle into engagement with the spliced end portions after which the cover is moved relative to the base plate to shear across the coating material along the interface between the cover and the base plate. Movement is discontinued when a channel (86) in the cover becomes aligned with the recoated splice. This allows the coating material to be solidified in the presence of a free surface (90) which avoids the formation of bubbles in the coating material and causes the recoated portion to remain in engagement with the original coated portions adjacent to the spliced end portions.

摘要： A method of forming optical fibers with improved mode dispersion characteristics is disclosed. The technique involves differential mode-group delay measurement to optimize dispersion by means of appropriate index of refraction configurations. The differential delay measurement technique involves selectively launching light into the multimode fiber using a single mode fiber which is spliced to the multimode fiber using an adjustable splice including an index matching fluid.

摘要： The present invention is a device which may be used to detect the presence of light in a single mode optical fiber while the optical fiber is in use, or to introduce light into an optical fiber. The device includes an identifier chip, and an associated, complementary shaped plate, each of which employ both microbending and macrobending portions. The chip and the plate are each formed of a single piece of material, although only the chip must be formed of an optically transmissive material. In use the chip is urged toward the plate with an optical fiber therebetween. Deformation of the fiber caused by the stress exerted by the chip and the plate will cause detectable light to be emitted through the chip if the fiber is live.
