Description
Vynález sa týká spósobu výroby spojky pre spájanie jednovláknových optických káblov.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a splice for splicing single-fiber optic cables.
Doteraz známe spósoby riešia spájanie optických káblov pomocou pevných alebo rozoberatelných spojok. Rozoberatelné spájanie optických káblov je realizované pomocou optických konektorov.The known methods have been used to solve optical cables by means of fixed or demountable couplings. Detachable connection of optical cables is realized by optical connectors.
Ich nevýhodou je náročnost výroby a montáže, a tým aj vysoká cena. Montáž konektorov vyžaduje Speciálně zariadenie a vo vSčšine prípadov ho musi zabezpečit výrobca. Pri druhom spósobe výroby spojok sa optické vlákna spájajú pevne zváranim alebo lepením. Nevýhodou týchto spojok je,Se sú určené pre viacvláknové optické káble priemeru 8 až 20 mm, a teda sú poměrně rozměrné, nakolko je nutné uložit v nich potřebné rezervy vlákien, ktoré predstavujú 1 až 1,5 m z každej strany. Prespájanie jednovláknových optických káblov je použitie týchto spojok značné neekonomické a neúčelné vzhladom na ich priemer, ktorý je 2,5 až 4,5 mm.Their disadvantage is the difficulty of production and assembly and hence the high price. The installation of the connectors requires a special device and must in most cases be provided by the manufacturer. In the second method of manufacturing couplings, the optical fibers are joined by welding or gluing. The disadvantage of these couplings is that they are designed for 8 to 20 mm diameter multi-fiber optic cables and are therefore relatively large in size because they need to accommodate the necessary fiber reserves of 1 to 1.5 m from each side. The interconnection of single-fiber optic cables makes the use of these couplings considerably uneconomical and ineffective because of their diameter of 2.5 to 4.5 mm.
Uvedené nevýhody doterajšieho stavu odstraňuje riešenie podlá vynálezu, ktorého podstata spočívá v tom, že miesto zvaru sa po zvareni vlákien najprv pokryje silikonovou vrstvou, potom sa na upravený spoj navlečie zmraštitelná polyetylénová rúrka, ktorá sa zmraští pri teplote minimálně 100 °C a na takto vytvořený hermetický spoj sa navlečie ocelová spevňovacia rúrka, ktorej konce sa nalisujú na spájaný kábel a následné sa vytvoří vonkajší obal zo zmraštitelnej polyetylénovéj rúrky, ktorá sa taktiež zmrašti pri teplote minimálně 100 °C.The above-mentioned disadvantages of the prior art are eliminated by the solution according to the invention, which consists in that the place of the weld is first covered with a silicone layer after the welding of the fibers, then shrinked polyethylene tube The hermetic joint is threaded through a steel reinforcing tube, the ends of which are pressed onto the cable to be bonded, and subsequently an outer sheath of the shrinkable polyethylene tube is formed, which also shrinks at a temperature of at least 100 ° C.
Riešenie spósobu výroby spojky pre spájanie jednovláknových optických káblov podlá vynálezu má výhody v tom, že sa ňou vylúči komplikovaná a náročná montáž konektorov, pričom sa dosiahne nižšie přechodové tlmenie. Tým, že sa vlákno zvarí pomocou vhodného zariadenia a obnovia sa ochranné a spevňovacie prvky sa zabezpečia dokonale hermeticky a mechanicky chráněné miesta spoja. V případe požiadavky nerozoberatelnosti spoja je vzhladom na nižšie přechodové tlmenie dokonalejšou náhradou za spoj pomocou optických konektorov.The method of manufacturing a coupling for splicing single-fiber optic cables according to the invention has the advantage that it avoids the complicated and demanding assembly of the connectors, while achieving lower transient damping. By welding the fiber with a suitable device and restoring the protective and reinforcing elements, perfectly hermetically and mechanically protected joints are provided. In the case of the requirement of non-releasable connection, due to the lower transient damping, it is a better replacement for the connection by means of optical connectors.
Podstata riešenia je 3alej dokumentovaná v konkrétnom přiklade vyhotovenia. Jednovláknové optické vlákna sa upravili tak, že na dlžke 30 mm od konca sa odstránil plášt a nosné spevňovacie prvky a na dlžke 12 mm sa odstránila sekundárná a primárná ochrana. Na jeden zo spájaných káblov sa navliekla vonkajšia teplom zmraštitelná PE rúrka, ocelová rúrka a vnútorná teplom zmraštitelná polyetylénová rúrka. Spájané káble sa upevnili do zvarovaoieho zariadenia a zvarili sa optické vlákna. Na zvarené miesto sa naniesla silikonová vrstva slúžiaca ako obnova primárnej ochrany. Potom sa na toto miesto přesunula vnútorná ochranná teplom zmraštitelná polyetylénová rúrka, ktorá sa plameňom zmraštila. Ocelová spevňovacia rúrka, ktorá sa přesunula tak, aby zachytávala oba spájané káble, mala vnútorný priemer o 0,2 mm vSčší ako je vonkajší priemer spájaného optického kábla. Po navlečení sa oba konce ocelověj rúrky nalisovali lisovacími kliešťami na spájané konce káblov. Nakoniec sa navliekla vonkajšia ochranná teplom zmraštitelná polyetylénová rúrka a zmraštila sa plameňom.The essence of the solution is further documented in a specific exemplary embodiment. The single-fiber optic fibers were treated by removing the sheath and support reinforcement at a length of 30 mm from the end, and removing the secondary and primary protection at a length of 12 mm. An outer heat shrinkable PE pipe, a steel pipe and an inner heat shrinkable polyethylene pipe were threaded onto one of the cables to be connected. The spliced cables were fixed to the welding machine and the optical fibers were welded. A silicone layer was applied to the welded spot to restore primary protection. The internal heat-shrinkable polyethylene tube was then moved to this location and shrinked by the flame. The steel reinforcing tube, which was moved to grip the two cables to be connected, had an inner diameter 0.2 mm higher than the outer diameter of the fiber optic to be connected. After threading, both ends of the steel tube were pressed with crimping pliers onto the soldered ends of the cables. Finally, an outer protective heat-shrinkable polyethylene tube was threaded and shrunk by flame.
Riešenie podlá vynálezu možno využit v elektrotechnike pri budovaní lokálnych sietí s optickými káblami, připadne pri opravě náhodného prerušenia už existujúcich lokálnych sietí.The solution according to the invention can be used in electrical engineering to build local networks with fiber optic cables or to repair accidental interruptions of existing local networks.
