M'dziko lazolumikizana ndi matelefoni, zingwe za fiber optic zakhala mulingo wagolide pakutumiza kwa data mwachangu kwambiri. Zingwe zimenezi ndi zoonda kwambiri za magalasi kapena ulusi wa pulasitiki zomwe zimamangidwa pamodzi kuti zipange nsewu waukulu wa data womwe umatha kutumiza mauthenga ochuluka pa mtunda wautali. Komabe, kuti zitsimikizidwe kuti zilumikizidwe mosadodometsedwa, zingwezi ziyenera kulumikizidwa bwino kwambiri.
Kuphatikizika ndi njira yolumikizira zingwe ziwiri za fiber optic kuti mupange kulumikizana kosalekeza. Zimaphatikizapo kugwirizanitsa mosamalitsa nsonga za zingwe ziwirizi ndikuziphatikiza pamodzi kuti zikhale zolumikizana mopanda msoko, zotayika pang'ono. Ngakhale kuti njirayi ingawoneke ngati yowongoka, imafunikira luso lapamwamba ndi luso kuti mukwaniritse zotsatira zomwe mukufuna.
Kuti ayambe ntchitoyi, katswiriyo amavula kaye zokutira zoteteza ku zingwe ziwiri za fiber optic kuti ziwonetsere ulusi wopanda kanthu. Kenako ulusiwo umatsukidwa ndi kung’ambika pogwiritsa ntchito chida chapadera kuti ukhale wosalala komanso wosalala. Katswiriyo ndiye amagwirizanitsa ulusi uŵiriwo pogwiritsa ntchito maikulosikopu ndi kuulumikiza pamodzi pogwiritsa ntchito fusion splicer, yomwe imagwiritsa ntchito arc yamagetsi kusungunula ulusiwo ndi kusakaniza pamodzi.
Ulusiwo ukangosakanikirana, katswiri amawunika mosamala nsongayo kuti atsimikize kuti ikukwaniritsa zofunikira. Izi zikuphatikizapo kuyang'ana zizindikiro zilizonse za kutuluka kwa kuwala, zomwe zingasonyeze kuti pali kusiyana kopanda ungwiro. Katswiriyu athanso kuchita mayeso angapo kuti ayeze kutayika kwa chizindikiro ndikuwonetsetsa kuti splice ikugwira ntchito bwino.
Ponseponse, kuphatikiza zingwe za fiber optic ndizovuta kwambiri zomwe zimafuna ukadaulo wapamwamba komanso kulondola. Komabe, pogwiritsa ntchito zida ndi njira zoyenera, akatswiri amatha kutsimikizira kulumikizana kosasunthika komanso kufalitsa deta yodalirika pamtunda wautali.
Mitundu ya Splicing
Pali njira ziwiri zolumikizirana, makina kapena maphatikizidwe. Njira zonsezi zimapereka kutayika kotsika kwambiri kuposa zolumikizira za fiber optic.
Mechanical splicing
Optical cable mechanical splicing ndi njira ina yomwe sifunikira fusion splicer.
Ma splices amakina ndi ma splices a mikwingwirima iwiri kapena kuposerapo yomwe imalumikizana ndikuyika zigawo zomwe zimasunga ulusiwo pogwiritsa ntchito index yofananira madzimadzi.
Kulumikizana kwamakina kumagwiritsa ntchito kaphatikizidwe kakang'ono kakang'ono pafupifupi masentimita 6 m'litali ndi pafupifupi 1 cm m'mimba mwake kuti alumikizane kwamuyaya. Izi zimayenderana bwino ndi zingwe ziwirizo ndikuziteteza mwamakina.
Zovundikira, zomatira, kapena zonse ziwiri zimagwiritsidwa ntchito kuteteza splice mpaka kalekale.
Ulusiwo sunalumikizidwe kotheratu koma amalumikizana pamodzi kuti kuwala kumadutsa kuchokera kumodzi kupita ku mnzake. (kutayika kolowetsa <0.5dB)
Kutayika kwa splice nthawi zambiri kumakhala 0.3dB. Koma fiber mechanical splicing imayambitsa zowoneka bwino kuposa njira zophatikizira.
The Optical cable mechanical splice ndi yaying'ono, yosavuta kugwiritsa ntchito, komanso yabwino kukonzanso mwachangu kapena kukhazikitsa kosatha. Ali ndi mitundu yokhazikika komanso yolowetsedwanso.
Optical cable mechanical splices ilipo ya single-mode kapena multi-mode fiber.
Fusion splicing
Fusion splicing ndi yokwera mtengo kuposa kuphatikizika kwamakina koma kumatenga nthawi yayitali. Njira yophatikizira ma fusion imasakaniza ma cores ndi kuchepa pang'ono. (kutayika kowonjezera <0.1dB)
Panthawi yophatikizika, chophatikizira chodzipatulira chimagwiritsidwa ntchito kulumikiza mbali ziwiri za ulusi, ndiyeno magalasi amatha "kusakanikirana" kapena "kuwotcherera" palimodzi pogwiritsa ntchito arc yamagetsi kapena kutentha.
Izi zimapanga kulumikizana kowonekera, kosawoneka bwino, komanso kosalekeza pakati pa ulusi, zomwe zimapangitsa kutulutsa kwapang'onopang'ono kwa kuwala. (Kutayika kwenikweni: 0.1 dB)
The fusion splicer imapanga optical fiber fusion mu masitepe awiri.
1. Kuyanjanitsa kolondola kwa ulusiwo
2. Pangani arc pang'ono kuti musungunule ulusi ndikuwotcherera palimodzi
Kuphatikiza pakutayika kocheperako kwa 0.1dB, maubwino a splice amaphatikizanso zowunikira zochepa zakumbuyo.
