Our method of making high bandwidth silica-based multimode optical fiber comprises provision of a non-circular preform, and drawing fiber of chiral structure from the preform. The non-circular preform can be made by maintaining the inside of the tubular preform under reduced pressure during at least part of the collapse, resulting in a non-circular core and cladding. It can also be made by removal (e. g. , by grinding or plasma etching) of appropriate portions of the preform, resulting in a circular core and non-circular cladding. In the latter case, fiber is drawn at a relatively high temperature such that, due to surface tension, the cladding assumes substantially circular shape and the core assumes a non-circular shape. The chiral structure is imposed on the fiber in any appropriate way, e. g. , by twisting during fiber drawing the fiber alternately in clockwise and couterclockwise sense relative to the preform.

Embodiments of the invention include an optical communications system including a multimode optical fiber having improved overfill-launch bandwidth performance without disturbing existing laser-launch bandwidth performance. The multimode optical fiber has a characteristic differential mode delay with a first portion associated with lower order modes that behaves conventionally and a second portion associated with higher order modes that deviates from conventional behavior in a way that improves overfill-launch bandwidth performance at one operating window without adversely impacting the laser-launch bandwidth performance at the same and other operating windows. Multimode optical fibers conventionally optimized for operation at 850 nm are configured in such a way that their characteristic differential mode delay, at 1300 nm, initially increases in a conventional manner and then flattens out to approximately zero at the higher order modes. At 850 nm, the characteristic differential mode delay initially remains flat at approximately zero, in a conventional manner, and then decreases at the higher order modes. Also, embodiments of the invention include an inventive optical fiber preform configured appropriately to produce the desired differential mode delay, and a method for making the inventive optical fiber preform.

A variable attenuator has first and second substantially identical ferrules or capillaries, each being mounted in a barrel or splice housing and extending toward each other, with their distal ends being separated by a gap of a first width. The width of the gap is controlled by a sleeve into which the ferrules are inserted, the ends of the sleeve butting against the front faces of the barrels. The ferrules are made by producing a glass rod mounted between the barrels and having a bore offset from and parallel to the centerline of the rod and breaking or cleaving the rod at its longitudinal center. The broken ends are then polished. The barrels are keyed to a housing member so that the offset bores are coincident in the zero position as defined by the keys.

A fiber optic cable suitable for blowing into and through ducts containing pressurized gas, such as natural gas, has the fibers therein arranged in arrays that form longitudinally extending vents. The vents are blocked from transmission of any gas by each being filled with a compliant member which assumes the cross-sectional shape of the vents thereby blocking it. In a second embodiment of the invention, the first and third ferrules are fixed within the housing with their offset bores in alignment. A second ferrule is interposed between the first and third ferrules and is mounted in a rotatable member for misaligning the bore in the second ferrule with the bores in the first and third ferrule to produce attenuation of a signal passing through the ferrules by misaligning the fibers contained in the bores.
