A device for collection and storage of waste monofilament line or similar materials. The device has a rotating spool mechanism in the form of an inner spool with an outer surface to which line adheres rotated by a rotation operator coupled to the spool. An outer cylinder encloses the spool mechanism. Monofilament line is passed through a window in the outer cylinder and adheres to the outer surface of the spool. The rotation operator is rotated, drawing the line into the device for storage and later disposal.

A perturbed, multimode optical fiber exhibits order-of-magnitude improved capacity attributed to mode mixing&#x2014;high per-channel bit rate, and large channel number due to large available bandwidth&#x2014;without the added loss which, in the past, was associated with the perturbation stream.

Single-mode optical fiber systems, incorporating fiber of core radius of sufficient size to support the fundamental mode together with from one to three higher order modes, exhibit performance/cost advantages relative to systems based on traditional single-mode fiber.

Single-mode fiber systems

Multimode optical fiber local area networks, both intrabuilding and interbuilding, are optimized to take advantage of the wide wavelength operating range offered by co-pending patent application Ser. No. 10/408,076 'Enhanced Multimode Fiber' &#x2014;a fiber provided both with: longitudinally spaced perturbations for inducing mode coupling and thereby lessening mode dispersion; and with a radial discontinuity for discouraging conversion of bound-to-cladding-modes and thereby lessening added loss previously associated with induced mode coupling.

High-capacity multimode optical fiber systems

A single-mode fiber of increased core size consists of a 'few-mode' fiber, of core size sufficient for guiding up to three high-order modes in addition to the fundamental mode, by interposing perturbations of such spacing along the fiber, as to selectively couple any such high-order modes to (unguided) cladding modes, thereby rejecting all but the fundamental mode. Unwanted coupling of the fundamental mode, leading to added fiber loss, is minimized by appropriate refractive index profile design.

Variable attenuator for optical fiber applications

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 system for cross-connecting network elements of different types through a common universal media. In the system, a media conversion interface is electrically connected to a network element. This media conversion interface passively maps the connector and cable type of the network element to a universal connector type. This media conversion interface is electrically connected to a cross-connect module in a universal distribution frame. This electrical connection uses a universal cable group and universal connectors. This cross-connect module is connected to another cross-connect module, also in a universal distribution frame, using a universal cable group and universal connectors. This second cross-connect module is electrically connected to a second media conversion interface, using a universal cable group and universal connectors. This second media conversion interface is electrically connected to a second network element, and passively maps the connector and cable type of the second network element to the universal connector.

A connector plug for an optical fiber polarization maintaining connector has a front housing portion from which extends a cantilevered latching arm having a cross-sectional shape of a truncated wedge, and a rear housing portion. A barrel assembly having a flange thereon and a ferrule extending therefrom is housed within said first and second portions and is incrementally rotatable with respect to the first portion of the housing and hence to the latching arm. In a first embodiment the flange is seated in the front portion and prevented from turning with respect thereto. In a second embodiment the rear housing portion is an extender cap having resilient clamping arms which grip the flange. The extender cap is incrementally rotatable with respect to the first portion of the housing and, hence, the ferrule is incrementally rotatable with respect to the latching arm.

A method and apparatus for overcoming modal noise penalties associated with multi-mode fiber optic links operating at high data rates on the order of 10 Gb/s. The method involves restricting the center launch condition of optical signals into the multi-mode fiber while permitting loose tolerances between source and fiber.
