A method for manufacturing an optical fiber spool includes winding a coil of an optical fibers up in the form of a cross-winding such that several layers of the optical fiber are formed that lie on top of one another. The optical fiber has a surface that respectively features contact areas between adjacent layers. Elevations are produced on the surface to create intermediate spaces between the elevations. The elevations are distributed so that in the region of one of the respective contact areas, at least one of the elevations of one of the adjacent layers of the respective contact area engages into at least one of the intermediate spaces of the other adjacent layer to of the same contact area. An optical fiber spool with a self-supporting coil of an optical fiber can be produced.

A method and a device for launching an underwater moving body. In order to reduce the expenses arising from furnishing watercraft, a land supported deployment of underwater moving bodies in coastal waters using a launching device is provided with a land-based carrier system for transporting the underwater moving body and a corresponding land-based deploying system.

The invention relates to a fiberglass spool comprising a self-supporting roll () having layers of windings () located one above the other of an optical fiber () for transmitting data that may be unwound from the interior of the roll outwards, wherein the windings () are fixed to one another by means of an adhesive bonding agent. In order to realize a sufficiently stable, self-supporting roll () that may be reliably unwound from the inside outwards without loops being pulled out of the roll (), the roll () is structured as a cross-winding and a hydrocarbon-based, salt water-resistant, chemically inert impregnating material that may be liquefied by heating is used as the bonding agent.
