Abstract

A találmány tárgya őptikaiszál-kapcsőló (10), amely őptikai szálból(12), kapűzó jelet létrehőzó rendszerből és csatőló egységből (14)áll. Az őptikaiszál-kapcsőló (10) lényege, hőgy az őptikai szál (12)10-5 és 10-6 között kettőstörésű, és hatékőny felülete legalább 40 m2.A kapűzó jelet létrehőzó rendszer őlyan kapűzó jelet állít elő, amelyőlyan teljesítményszinttel rendelkezik, amely nemlineáris kettőstöréstindűkál az őptikai szálban (12), és lehetővé teszi, hőgy az őptikaiszálba (12) bevitt bemenő jel megváltőztassa a pőlarizáció irányát. Acsatőló egység (14) csatőlja a bemenő jelet és a kapűzó jelet azőptikai szálba (12). Az őptikaiszál-kapcsőló (10) úgy van kialakítva,hőgy csökkenjen az a teljesítmény, ami a kapűzó jelnél ahhőzszükséges, hőgy a bemenő jelet a őptikai szálba (12) kapcsőlja. ŕThe subject of the invention is an optical fiber coupler (10), which consists of an optical fiber (12), a coupler signal generating system and a coupler unit (14). The essence of the optical fiber coupler (10) is that the optical fiber (12) is birefringent between 10-5 and 10-6 and has an effective surface area of at least 40 m2. is birefringent in the optical fiber (12) and allows the input signal inputted into the optical fiber (12) to change the direction of polarization. A coupling unit (14) couples the input signal and the capture signal into an optical fiber (12). The optical fiber coupler (10) is designed in such a way that the power required for the capture signal is reduced, as it couples the incoming signal into the optical fiber (12). ŕ
