A method of manufacturing an optical fiber, in which a coating is provided on a bare optical fiber, includes winding the optical fiber around a bobbin such that a strain relaxation coefficient T.sub./K is less than or equal to 292, and an one-layer strain .sub.n is greater than or equal to 0.01.

There is provided a wound thread package that is unlikely to cause problems such as cob-webbing and collapse at the time of unwinding even when the wound thread is a multi-filament thread or tape-like thread, and a manufacturing method for the same.

To manufacture a wound thread package 1 by winding a plurality of multi-filament threads or tape-like threads having a total fineness of 100 to 6400 dtex per thread around a bobbin 2 by a traverse method, the threads constituting a thread layer 3 are arranged at intervals therebetween and wound with the same in traverse width w and at different traverse reverse positions.

Holders for wound cables. The holders include retention features to control the rate at which cable windings are unwound during cable deployment. In some examples, the cable holder includes a pair of spaced apart spools and the cable is wound in windings configured as figure-8's. In some examples, the retention features include flexibly resilient fingers positioned to contact the windings at one or more retention points positioned at a deployment end of the holder.

A payout tube has an inner end and an outer end. The inner end is disposable in an interior of a coil of filamentary material wound in a figure-eight configuration defining a payout hole. The outer end is configured to extend outwardly from the payout hole of the coil. The payout tube has a flange at the outer end and has a rounded edge at the inner end. The rounded edge has a radius between 0.20 and 0.30 inch. In some embodiments, the payout tube includes a tubular body that extends between the flange and the rounded edge. In other embodiments, the payout tube includes an outer ring having the flange, an inner ring having the rounded edge with the inner and outer rings aligned coaxially about a longitudinal axis in spaced relation, and a plurality of pillars extending longitudinally from the outer ring to the inner ring.

A one hand spinning reel system includes a fixed spool and a bail coupled to a trigger switch for opening and optionally closing the bail, and a solid spindle coupled to a motor that is controlled by a motor switch. When the one hand spinning reel system is affixed to a fishing rod, the trigger switch and the motor switch can be operated, and the fishing line can be controlled, using the same hand used to hold the fishing rod and to cast the fishing line.

A spool of optical fibre comprises a spool axis and a length of optical fibre wound around the spool axis to form a plurality of wrap segments arranged axially along the spool axis, wherein adjacent wrap segments partially overlap in the axial direction. Each wrap segment comprises a first wrap layer wound in a first axial direction over a first axial distance, and a second wrap layer wound over the first wrap layer in a reverse second axial direction over a second axial distance greater than the first axial distance, the optical fibre extending from the second wrap layer of one wrap segment to the first wrap layer of an adjacent wrap segment. The spool may be mounted in a device such that the optical fibre can be despooled and deployed from the device.
