摘要： A multicore optical fiber includes a plurality of core regions disposed within a common cladding region. Each of the plurality of core regions is configured, in combination with the common cladding region, to propagate light along a longitudinal axis of the fiber. At least two core regions are configured to inhibit resonant coupling of propagated light therebetween within a selected region of operation. At least one segment of the fiber includes a twist that is configured such that when the twisted segment is subjected to a bend having a selected radius, the twist creates a controlled change in the amount of crosstalk between the at least two core regions, compared with the amount of crosstalk between the at least two core regions when a bend having the selected radius is introduced into a non-twisted segment of the fiber.

摘要： A length of optical fiber has a core, a cladding layer surrounding the core and a coating layer applied over the cladding layer along the fiber for protecting the fiber. The coating layer is applied so that gaps of a certain width are defined intermittently in the coating layer over the length of fiber. The gaps in the coating layer have a depth D that is set to expose the cladding layer enough within the gaps so that the exposed cladding layer and the surrounded core can be fusion spliced or terminated with minimal if any required stripping of the coating layer off of the cladding layer.

摘要： A safety device for modules that store windings of communication lines, includes a metallic rod whose ends are configured to receive metallic screws to secure the rod on a base of a given module. End sections of the rod extend to a height at least equal to the height of the stored windings. Intermediate sections of the rod extend in opposite directions from the end sections, substantially parallel to the module base. Outer ends of the intermediate sections at least coincide with the outer periphery of the stored windings. A central section of the rod has opposite ends adjoining the outer ends of the intermediate sections. The central section rises over a path that at least coincides with the outer periphery of the stored windings. The end sections of the rod capture the windings, and the central section prevents them from dropping below the module during a building fire.

摘要： An optical fiber storage module (10) has a base (14), and a wall (16) having an opening (16a) for paying out an optical fiber from inside the module. Spool retention fingers (32) extend from the base. One or more fingers have a first rim (32a) at a first height above the base, and one or more fingers have a second rim (34a) at a second height above the base. A fiber supply spool (40) has a hub (42), and an annular support disk (54) inside the hub (42) which forms a third rim (58). The spool (40) is movable on the retention fingers (32) between a first position where the third rim (58) of the support disk is captured between the first (32a) and the second rims (34a) on the retention fingers, thus allowing the spool to turn when fiber is unwound, and (b) a second position where the spool (40) engages one or more bosses (28) formed on the module base (14) to lock the spool from further rotation.

摘要： A tight-buffered optical fiber cable includes an improved method of accessing the coated optical fiber. The cable can include an optical fiber having a glass core and a cladding layer. One or more coating layers can be applied about the cladding layer. A buffer jacket material can be applied onto an outer surface of the outer coating layer as a buffer jacket outer layer. The buffer jacket outer layer can have distinctive features including a low tear strength, low elastic modulus, high elongation percentage, and low peeling force. This can allow a user of the optical fiber cable to separate at least a portion of the coated optical fiber from the buffer jacket outer layer by grasping a free end of the coated optical fiber and pulling it through the outer wall of the buffer jacket outer layer, thereby tearing through the outer wall of the buffer jacket outer layer.

摘要： An optical fiber has a core region that is doped with one or more viscosity-reducing dopants in respective amounts that are configured, such that, in a Raman spectrum with a frequency shift of approximately 600 cm -1 , the fiber has a nanoscale structure having an integrated D2 line defect intensity of less than 0.025. Alternatively, the core region is doped with one or more viscosity-reducing dopants in respective amounts that are configured such that the fiber has a residual axial compressive stress with a stress magnitude of more than 20 MPa and a stress radial extent between 2 and 7 times the core radius.
According to another aspect of the invention a majority of the optical propagation through the fiber is supported by an identified group of fiber regions comprising the core region and one or more adjacent cladding regions. The fiber regions are doped with one or more viscosity-reducing dopants in respective amounts and radial positions that are configured to achieve viscosity matching among the fiber regions in the identified group.
