Chingwe chonyamula zidandi chingwe chowunikira chokhala ndi "zida" zoteteza (chubu chachitsulo chosapanga dzimbiri) chokulungidwa pakati pa fiber. Chubu chachitsulo chosapanga dzimbiri chankhondo ichi chimatha kuteteza pachimake cha ulusi kuti zisalumidwe ndi nyama, kukokoloka kwa chinyezi kapena kuwonongeka kwina. Mwachidule, zingwe zopangira zida zankhondo sizingokhala ndi mawonekedwe a zingwe zowoneka bwino, komanso zimapereka chitetezo chowonjezera cha ulusi wamagetsi, kuzipangitsa kukhala zamphamvu, zodalirika komanso zolimba. Masiku ano, zingwe zamagetsi zokhala ndi zida ndiye chisankho chabwino kwambiri pamanetiweki amsukulu, malo opangira ma data ndi ntchito zamafakitale.
Kapangidwe kazida kuwala chingwe
1. Fiber Core: Chingwe chapakati ndi gawo lomwe limatumiza zizindikiro za data. Nthawi zambiri imakhala ndi ulusi umodzi kapena zingapo zowoneka bwino, chilichonse chimakhala ndi pachimake komanso chotchingira. Ulusi wapakati umagwiritsidwa ntchito kutumiza ma sign a kuwala kuchokera ku mbali imodzi kupita ku ina.
2. Filler (Buffer Material): Chojambuliracho chimakhala pakati pa chitsulo chapakati ndi zida zachitsulo, kudzaza kusiyana ndi kupereka chitetezo ndi chithandizo. Itha kukhala zinthu zotayirira za polima kapena chinthu chonga gel chomwe chimavala ulusi.
3. Zida Zachitsulo: Zida zachitsulo ndi gawo lofunika kwambiri la zingwe zopangira zida, zomwe zimapereka mphamvu zamakina ndi ntchito zoteteza. Zida zachitsulo nthawi zambiri zimapangidwa kuchokera ku waya wachitsulo wozungulira kapena malata, monga chitsulo kapena waya wa aluminiyamu. Ikhoza kukana kupsinjika monga kupanikizika, kupsinjika ndi kukhudzidwa kwa chilengedwe chakunja, ndikuteteza kuwala kwa mkati kuti zisawonongeke.
4. Jacket Yakunja: Jekete lakunja ndi gawo lakunja loteteza chingwe cha zida zankhondo. Nthawi zambiri amapangidwa ndi zinthu zokhala ndi zinthu zabwino zosavala, zoteteza komanso zosalowa madzi, monga PVC (polyvinyl chloride) kapena LSZH (yopanda utsi wochepa wa halogen). Jekete lakunja limateteza chingwe cha fiber optic kuti chisawonongeke kuchokera ku chilengedwe chakunja ndipo chimapereka chitetezo chowonjezera.
Mawonekedwe a zida za optical cable:
1. Kutetezedwa kwamakina: Chingwe chokhala ndi zida zankhondo chimakhala ndi mphamvu zamakina komanso kulimba, ndipo chimatha kupirira kukakamiza kwakunja, kupsinjika komanso kupsinjika. Izi zimalola zingwe zokhala ndi zida kuti ziteteze bwino ku kuwonongeka kwa ulusi m'malo ovuta kwambiri, monga kunja, mobisa kapena m'mafakitale.
2. Anti-external interference: Chitsulo chachitsulo chosanjikiza cha chingwe cha optical cha armored chingathe kukana kusokonezeka kwa electromagnetic ndi kusokoneza ma frequency a wailesi. Izi zikutanthauza kuti ngakhale m'madera okhala ndi mizere yambiri yamagetsi, zingwe zothamanga kwambiri kapena zinthu zina zosokoneza, zingwe zokhala ndi zida zokhala ndi zida zimatha kukhalabe ndi kukhulupirika kwachizindikiro komanso kufalitsa kwa data.
3. Kutengera kufalikira kwakutali: Chifukwa zingwe zokhala ndi zida zokhala ndi mphamvu zamakina komanso zoteteza, nthawi zambiri zimagwiritsidwa ntchito pamalo omwe kufalikira kwa fiber fiber mtunda wautali kumafunika. Chingwe chokhala ndi zida zankhondo chingathe kuchepetsa kuchepetsedwa ndi kutayika kwa ma siginecha owoneka bwino, potero kuwonetsetsa kukhazikika ndi kudalirika kwa ma sign panthawi yotumizira mtunda wautali.
4. Kulimbana ndi malo apadera: Muzochitika zina zogwiritsira ntchito, monga mauthenga a pansi pa nyanja, minda yamafuta, migodi, kapena malo ena ovuta, kugwiritsa ntchito zingwe zokhala ndi zida zotetezera kungathe kupereka chitetezo chabwino cha ulusi wa kuwala ndikuwathandiza kuti azitha kutentha kwambiri, chinyezi. , ndi mankhwala. ndi zina zapadera.
