Chingwe chowala chimatumiza ma siginecha ngati ma pulses, ndipo amagwiritsa ntchito galasi kapena plexiglass ngati njira yotumizira maukonde. Zimapangidwa ndi fiber core, zophimba komanso zoteteza. CHIKWANGWANI chamawonedwe akhoza kugawidwa mu Single Mode CHIKWANGWANI ndi Multiple Mode CHIKWANGWANI.
Single-mode optical fiber imangopereka njira imodzi ya kuwala, yomwe imakhala yovuta kuikonza, koma imakhala ndi mphamvu yolumikizirana yokulirapo komanso mtunda wautali wotumizira. Multimode fiber imagwiritsa ntchito njira zingapo zowunikira kuti zitumize chizindikiro chomwecho, ndipo liwiro lotumizira limayang'aniridwa ndi refraction ya kuwala.
Optical fiber nthawi zambiri imagwiritsidwa ntchito pofalitsa maukonde olumikizirana. Panthawi yopatsirana, mitundu yosiyanasiyana ya ulusi wowoneka bwino imasankhidwa malinga ndi chilengedwe komanso zofunikira zotumizira. Pali mitundu iyi ya ulusi wowoneka bwino womwe umagwiritsidwa ntchito pamanetiweki apakompyuta
A. 8.3pm pachimake / 125pm chipolopolo, single-mode kuwala chingwe;
B. 62.5um pachimake / 125um chipolopolo, multimode kuwala chingwe;
C. 5OPm pachimake / 125pm chipolopolo, multimode kuwala chingwe;
D. Loopm pachimake/140pm chipolopolo, multimode kuwala chingwe.
Chingwe chowunikira chimapangidwa makamaka ndi ulusi wowoneka bwino (tsitsi lagalasi lopyapyala ngati tsitsi) ndi manja oteteza pulasitiki ndi ma pulasitiki. Palibe zitsulo monga golide, siliva, mkuwa ndi aluminiyamu mu chingwe chowunikira, ndipo nthawi zambiri palibe mtengo wobwezeretsanso. Chingwe chowunikira ndi chingwe cholumikizirana chomwe ulusi wina wa kuwala umapanga chingwe pachimake mwanjira inayake, yomwe imakutidwa ndi sheath ndipo ina imaphimbidwanso ndi sheath yakunja kuti izindikire kufalikira kwa ma sign a kuwala. Ndiko kuti: chingwe chopangidwa ndi kuwala kwa fiber (optical transmission carrier) pambuyo pa ndondomeko inayake. Kapangidwe kake ka chingwe chowunikira nthawi zambiri kamapangidwa ndi chingwe core, waya wokhazikika wachitsulo, chodzaza, ndi sheath. Kuonjezera apo, palinso zigawo zina monga wosanjikiza madzi, wosanjikiza wosanjikiza, ndi insulated mawaya zitsulo ngati pakufunika.
Chifukwa chachikulu chakukula mwachangu kwa chingwe cha fiber optic ndikuti chimakhala ndi izi:
1. Bandiwifi yotumizira ndi yotakata kwambiri ndipo mphamvu yolumikizirana ndi yayikulu kwambiri;
2. Kutaya kwapang'onopang'ono kwapang'onopang'ono ndi mtunda wautali wa relay, makamaka woyenera kufalitsa mtunda wautali;
3. Mphamvu zotsutsana ndi mphezi ndi zotsutsana ndi ma electromagnetic kusokoneza;
4. Kusunga chinsinsi chabwino, chosavuta kumva kapena kulandidwa deta;
5. Kukula kochepa ndi kulemera kochepa;
6. Low bit zolakwa mlingo ndi mkulu kufala kudalirika;
7. Mtengo ukugwa mosalekeza.
Kapangidwe kake ka chingwe chowunikira nthawi zambiri kamapangidwa ndi chingwe core, waya wokhazikika wachitsulo, chodzaza, ndi sheath. Kuonjezera apo, palinso zigawo zina monga wosanjikiza madzi, wosanjikiza wosanjikiza, ndi insulated mawaya zitsulo ngati pakufunika. Chingwe chowoneka bwino chimapangidwa ndi pachimake cholimbitsa ndi chingwe, sheath ndi sheath yakunja. Pali mitundu iwiri ya mapangidwe amtundu wa chingwe: mtundu wamtundu umodzi ndi mitundu yambiri: mtundu wamtundu umodzi uli ndi mitundu iwiri: mtundu wathunthu ndi mtundu wa chubu; Multi-core mtundu uli ndi mitundu iwiri: riboni ndi mtundu wa unit. Mchimake wakunja uli ndi mitundu iwiri ya zida zachitsulo ndi zopanda zida.
Njira yopangira chingwe cha Optical nthawi zambiri imagawidwa m'njira zotsatirazi:
1. Kuwunika kwa ulusi wa kuwala: sankhani chingwe chowoneka bwino chokhala ndi mawonekedwe abwino kwambiri opatsirana komanso kukanika koyenera.
2. Kudetsedwa kwa ulusi wa kuwala: Gwiritsani ntchito chromatogram yokhazikika kuti mulembe chizindikiro, osafunikira kuzimiririka komanso kusamuka pa kutentha kwakukulu.
3. Extrusion yachiwiri: gwiritsani ntchito pulasitiki yokhala ndi zotanuka modulus yayikulu komanso yocheperako yokulirapo yocheperako kuti ipitirire mu chubu cha kukula kwake, ikani CHIKWANGWANI mu gel osagwirizana ndi chinyezi ndi madzi, ndikusunga kwa masiku angapo (osachepera awiri). masiku).
4. Chingwe chokhotakhota cha kuwala: potoza ulusi wambiri wotuluka kunja ndi chigawo cholimbitsa.
5. Finyani mchimake wakunja kwa chingwe cha kuwala: onjezerani chingwe chachitsulo chopotoka.
