Übersetzung für "Bare fiber" in Deutsch

Optical sensors are electrically passive and rely only on a bare optical fiber.

In comparison to the bare fiber, the preferably provided microlens fiber has the most homogeneous irradiation profile.

In this way, the splice location SS as well as the bare optical fiber sections AFI CFI can be re-coated.

In the coating of optical fibers by lacquering, the bare fiber passes immediately after drawing through one or generally several coating units each followed by a drying zone.

Surprisingly, the invention therefore solves several problems so that, in contrast to prior art devices, an alternate contact cutting as well as a no-contact coagulating becomes possible even by means of the bare fiber while the service life is prolonged.

The coating is removed at the end of the light guide 2 so that the bare optical fiber 2.1 projects into the interior 3 of the housing 1.

In the coating of optical fibers with plastic in order to obtain high tensile strength and for protection against mechanical damage, the bare fiber passes immediately after the drawing process through one or more coating devices, which are followed by respective drying sections (ovens) for hardening the plastic.

It can be particularly expedient to already separate the optical fiber AFI from the coating material of the connecting light waveguide ALW at the factory side or to already prefabricate the plug with a bare optical fiber from the very outset.

The bare fiber sections are surrounded by ceramic slurry and stuccoing material used in the production of investment casting mold shells and are thus firmly anchored in the mold shell which is being formed.

The power output from a glass fiber (bare fiber) typically having a diameter of 600 ?m is thus limited to a few Watt, which largely prevents therapeutic use of the principle in practice.

Other embodiments of metal sleeves 3', which when the soldered joint cools, ensure that the solder 11 shrinks on the bare glass fiber 7' are shown in FIGS.

A further result is that the solder 11 in the area of the recess 12 hermetically surrounds the bare, unmetallized glass fiber 7'.

Furthermore, in order to also eliminate any mechanical stress which may still be present in the bare fiber, which stress could also lead to an undesirable temperature dependence of the measuring signal, and in order to practically render the fiber free of any double refraction, the sensor fiber is annealed at approximately 830° C., having been wound as a coil.

A bare fiber, free of its fiber coating, is extremely sensitive even to minute mechanical forces and also to chemical influences and furthermore to water vapour diffusing into the fiber, the latter being able to render the fiber brittle.

According to the above-mentioned EP 0,856,737 A1 such a highly sensitive bare fiber is inserted into a capillary which assumes the function of the fiber coating.

According to the process of the invention, the preliminary body is released from the pattern material at its ends or edges, and the thus bare fiber sections, when forming the ceramic mold, are fixedly embedded therein.

Therefor, an optical subassembly (OSA) is produced in a suitable manufacturing method in particular from at least one optically transparent or optically semi-transparent medium, for example from a polymer, and is conformed to both exclusively incorporate the one or more converters in preferably optically transparent material, and to ensure the precise, direct alignment of the optical axis of the converter with the optical axis of the optical fiber, without a ferrule, bare fiber or lens.

Bare fiber splitter is a kind of ODN product suitable for PON networks that can be installed in the pigtail cassette, test instrument and WDM system, which minimizes the space occupation.

A compromise between the invisible but sensitive bare fiber POF and the black jacketed POF the POF with white PVC jacket was developed.

Even if there is a risc to damage the bare fiber POF with a sharp tool, a slight scratch must not interrupt the data transmission.

In the case of the use of biocompatible fibers such as for instance, carbon fibers, it is readily possible to lay bare the fibers on the surface by using a mechanical method later without damaging the fibers.

DISCLOSURE OF INVENTION It is the object of the invention to provide a method and a suitable device for releasably fixing bare glass fibers in a splicing device, so that there is practically no axial displacement of the glass fibers after they have been fixed.

Moreover, the spread-out bundle of individual fibers 21 from which the outer covering has been removed over part of their length are fixed to the fiber holding plate by means of a pivoted lever 22 and are again held, together with the bare glass fibers 23 stripped of their primary coating from another such bundle in a precision-guiding member 24 at the front end of the fiber holding plates 6, 10, each glass fiber 23 of one bundle lying next to the end of a glass fiber of the other bundle.

To fix the bare glass fibers 23, which, in the single-mode design, have a diameter of only 0.125 mm, so as to secure them against axial tensile action, the solder 16 of each solder bath 55 is heated until the solder liquefies, a narrow holding-down device is placed across the glass fibers 23 at the center of the solder bath, and the level of the solder is raised above the glass fibers by pressing the slide 17 into the trough.

Field of application for the Ultratoolkit is the fast plug assembly in the field or laboratory or the end surface processing of bare fibers.

With the employment of a shrink hose as a splice protection sleeve SU, the sleeve SU is expediently shrunken onto the longitudinal sections of the two bare optical fibers AFI, CFI.
