Description

15 20 25 7807155-2 lunda möjlighet att införa ett med avseende på sina kemiska reaktioner förutsebart fyllnadsämne för skilda uppgifter och under skilda termis- ka eller kemiska betingelser. Den kan därigenom med fördel även tjäna såsom korrosionsskydd, så att möjligen andra behandlingar av fiberytan kan bortfalla. Särskilt viktigt är det dock, att trots det fyllda höl- Jet en tillräcklig sidorörlighet för fibrerna kvarstår, så att töjning- ar och hoptryckningar och därmed ändringar av dämpníngsförmågan kan und- vikas. Lämpligen kan ledaren fyllas under tillverkningen. Därvid är det en förutsättning, att fyllnadsmassan är tillräckligt tunnflytande, för att exempelvis fyllnadsmaterialet skall kunna införas med hjälp av de 1 höljet införda ljusledarfibrerna och en därigenom alstrad släpström- ning, utan att detta kommer att störa framställningen av fibrer och hölje genom icke önskade avkylningsförlopp eller genom hindrande av ut- jämningsförlopp inom ramen för framställningen. Dessutom önskas, att fyllnadsmassan i sluttillståndet skall ha erhållit en viskositet, som förhindrar utflytande ur ledaren, men a andra sidan tillåter en rörel- se av ljusledarfibrerna, om även långsam. Därjämte fordras, att brygg- bildningstiden är tillräckligt lång, för att tillräckligt stora mäng- der fyllnadsmassa skall kunna tillföras. 15 20 25 7807155-2 lunda the possibility of introducing a filler which is foreseeable with respect to its chemical reactions for different tasks and under different thermal or chemical conditions. It can thereby advantageously also serve as corrosion protection, so that possibly other treatments of the fiber surface can be omitted. It is particularly important, however, that despite the filled casing, sufficient lateral mobility of the fibers remains, so that elongations and compressions and thus changes in the damping ability can be avoided. Conveniently, the conductor can be filled during manufacture. In this case, it is a prerequisite that the filling mass is sufficiently thin-liquid, for example that the filling material can be introduced with the aid of the fiber-optic fibers introduced into the casing and a tow flow generated thereby, without this interfering with the production of fibers and casing by undesired cooling processes. or by preventing a smoothing process within the framework of the petition. In addition, it is desired that the filling mass in the final state should have obtained a viscosity which prevents it from flowing out of the conductor, but on the other hand allows a movement of the light guide fibers, if also slow. In addition, it is required that the bridge formation time is long enough for sufficiently large amounts of filling mass to be supplied.

Enligt ett föredraget utföringsexempel kan ett svagt bryggbildan- de silikonharts användas som fyllnadsmaterial. Denna substans uppfyl- ler alla ovan beskrivna krav på tillräckligt sätt, sa att de uppställ- da önskemålen kan lösas.According to a preferred embodiment, a weakly bridging silicone resin can be used as the filling material. This substance meets all the requirements described above in a sufficient manner, so that the set requirements can be solved.

Andra möjligheter består i att använda polyesterhartser, termo- plastisk polyuretan-kautschuk eller svälld polystyren i olja. Alla dessa material uppfyller de uppställda kraven, varvid urvalet sker efter de olika användningsvillkoren för kabeln och motsvarande meka- niska, kemiska och termiska beteendemönster för materialet.Other possibilities are to use polyester resins, thermoplastic polyurethane rubber or swollen polystyrene in oil. All these materials meet the set requirements, the selection taking place according to the different conditions of use for the cable and the corresponding mechanical, chemical and thermal behavior patterns for the material.

Sammandrag Uppfinningen avser en längsvattentät ljusvågledarkabel. Ljusvag- ledaren är anordnad i ett löst hölje och mellanrummet mellan ledare och hölje är fyllt med en trögflytande substans. Som fyllnadsmaterial an- vänds silikonharts, polyesterharts, termoplastisk polyuretan-kautsohuk eller svälld polystyren.Summary The invention relates to a longitudinally watertight light waveguide cable. The light-wave conductor is arranged in a loose casing and the space between the conductor and the casing is filled with a viscous substance. Silicone resin, polyester resin, thermoplastic polyurethane rubber or swollen polystyrene are used as filling material.
