Zingwe za fiber optical fiber za m'madzi zimapangidwira makamaka kuti zizikhala zam'nyanja, zomwe zimapereka kufalitsa kokhazikika komanso kodalirika kwa data. Sagwiritsidwa ntchito polankhulana m'sitima yamkati komanso amagwiritsidwa ntchito kwambiri polumikizirana ndi nyanja yamchere komanso kutumiza ma data pamapulatifomu amafuta ndi gasi akunyanja, zomwe zimagwira ntchito yofunika kwambiri pamakina amakono apanyanja. Pofuna kuonetsetsa kuti ntchito za m’nyanja za m’mphepete mwa nyanja zikhazikika, zingwe za m’madzi za m’madzi zapangidwa kuti zisalowe madzi, zisavutike ndi kupanikizika, zisachite dzimbiri, zolimba pogwiritsa ntchito makina, komanso zotha kusinthasintha kwambiri.
Nthawi zambiri, kapangidwe ka zingwe za m'madzi za optical fiber zimaphatikizapo ulusi, sheath, zida zankhondo, ndi jekete lakunja. Kwa mapangidwe apadera kapena ntchito, zingwe za marine optical fiber zimatha kusiya zida zankhondo ndipo m'malo mwake zimagwiritsa ntchito zida zosavala kapena ma jekete apadera akunja. Kuonjezera apo, kuti agwirizane ndi malo osiyanasiyana, zingwe za m'nyanja za optical fiber zingaphatikizepo zigawo zosagwira moto, mamembala apakati / olimbikitsa, ndi zina zowonjezera madzi.
(1) Optical Fiber Unit
Fiber unit ndiye gawo lalikulu la zingwe zapanyanja zokhala ndi ulusi umodzi kapena zingapo.
Ulusi wa Optical ndiye gawo lapakati pa chingwecho, chomwe chimakhala ndi pachimake, chotchingira, ndi zokutira, chokhala ndi chozungulira chozungulira. Pachimake, chopangidwa ndi silica yoyera kwambiri, ndiyomwe imayang'anira kutumiza ma sign a kuwala. Chophimbacho, chomwe chimapangidwanso ndi silika woyera kwambiri, chimazungulira pachimake, chimapereka mawonekedwe owoneka bwino komanso kudzipatula kwapadera, komanso chitetezo chamakina. Chophimba, chosanjikiza chakunja cha ulusi, chimapangidwa ndi zinthu monga acrylate, mphira wa silicone, ndi nayiloni, kuteteza ulusi ku chinyezi ndi kuwonongeka kwamakina.
Ulusi wowoneka bwino nthawi zambiri umagawidwa kukhala ulusi wamtundu umodzi (mwachitsanzo, G.655, G652D) ndi ulusi wamitundu yambiri (mwachitsanzo, OM1-OM4), wokhala ndi mawonekedwe osiyanasiyana otumizira. Zofunikira zopatsirana zimaphatikizira kuchepetsedwa kwakukulu, bandwidth yochepa, index refractive index, kabowo ka manambala, ndi kuchuluka kwa kubalalitsidwa kokwanira, komwe kumatsimikizira kuchuluka kwake komanso mtunda wa kutumizira ma siginecha.
Ulusiwo umazunguliridwa ndi machubu otayirira kapena olimba kuti achepetse kusokoneza pakati pa ulusi ndi kukhudzidwa kwa chilengedwe. Mapangidwe a fiber unit amaonetsetsa kuti deta imatumizidwa moyenera, ndikupangitsa kuti ikhale gawo lofunikira komanso lofunika kwambiri la zingwe zam'madzi za optical fiber.
(2) M’chimake
Fiber sheath ndi gawo lofunikira la chingwe, kuteteza ulusi wa kuwala. Kutengera kapangidwe kake, itha kugawidwa m'machubu olimba kwambiri komanso machubu otayirira.
Machubu olimba kwambiri amapangidwa ndi zinthu monga polypropylene resin (PP), polyvinyl chloride (PVC), ndi polyethylene yopanda malawi yamoto (HFFR PE) yopanda halogen. Machubu olimba otchinga amamatira kwambiri pamtunda, osasiya mipata yayikulu, yomwe imachepetsa kuyenda kwa fiber. Kuphimba kolimba kumeneku kumapereka chitetezo chachindunji kwa ulusi, kuteteza chinyezi kulowera ndikupereka mphamvu zamakina apamwamba komanso kukana kusokoneza kwakunja.
Machubu a buffer otayirira nthawi zambiri amapangidwa ndi high-modulusMtengo PBTpulasitiki, yodzazidwa ndi gel oletsa madzi kuti apereke chitetezo ndi chitetezo. Machubu a loose buffer amapereka kusinthika kwabwino kwambiri komanso kukana kukakamizidwa kotsatira. Gel yotchinga madzi imalola ulusi kuyenda momasuka mkati mwa chubu, kumathandizira kuchotsa ndi kukonza. Zimaperekanso chitetezo chowonjezereka ku zowonongeka ndi kulowetsa chinyezi, kuonetsetsa kuti kukhazikika ndi chitetezo cha chingwe m'madera amvula kapena pansi pa madzi.
(3) Gulu Lankhondo
Zida zankhondo zimakhala mkati mwa jekete lakunja ndipo zimapereka chitetezo chowonjezera cha makina, kuteteza kuwonongeka kwa thupi pa chingwe cha marine optical fiber. Zosanjikiza zida zankhondo nthawi zambiri zimapangidwa ndi galvanized steel wire braid (GSWB). Chomangira choluka chimakwirira chingwe ndi mawaya achitsulo, nthawi zambiri amakhala ndi chiwopsezo chosachepera 80%. Zida zankhondo zimapereka chitetezo champhamvu kwambiri pamakina komanso mphamvu zolimba, pomwe mapangidwe oluka amatsimikizira kusinthasintha komanso utali wopindika pang'ono (malo opindika ovomerezeka opindika a zingwe za m'madzi ndi 20D). Izi zimapangitsa kuti ikhale yoyenera pamapulogalamu omwe amafunikira kusuntha pafupipafupi kapena kupindika. Kuphatikiza apo, zida zachitsulo zokhala ndi malata zimapereka kukana kwa dzimbiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo achinyezi kapena opopera mchere.
(4) Jacket Yakunja
Jekete yakunja ndi chitetezo chachindunji cha zingwe za m'madzi za optical fiber, zomwe zimapangidwira kuti zisawonongeke ndi kuwala kwa dzuwa, mvula, kukokoloka kwa madzi a m'nyanja, kuwonongeka kwachilengedwe, kuwonongeka kwa thupi, ndi kuwala kwa dzuwa. Jekete lakunja limapangidwa ndi zinthu zosagwirizana ndi chilengedwe monga polyvinyl chloride (PVC) ndi zero-halogen yotsika utsi.Mtengo wa LSZH) polyolefin, yopereka kukana kwa UV bwino, kukana nyengo, kukana mankhwala, komanso kuchedwa kwamoto. Izi zimatsimikizira kuti chingwecho chimakhala chokhazikika komanso chodalirika pansi pa zovuta zapanyanja. Pazifukwa zachitetezo, zingwe zambiri zam'madzi zamadzimadzi tsopano zimagwiritsa ntchito zida za LSZH, monga LSZH-SHF1, LSZH-SHF2, ndi LSZH-SHF2 MUD. Zipangizo za LSZH zimapanga utsi wochepa kwambiri ndipo zilibe ma halogen (fluorine, chlorine, bromine, etc.), kupewa kutulutsa mpweya wapoizoni panthawi yoyaka. Mwa izi, LSZH-SHF1 ndiyomwe imagwiritsidwa ntchito kwambiri.
(5) Wosanjikiza Moto
M'madera ovuta, kuti atsimikizire kupitiriza ndi kudalirika kwa njira zoyankhulirana (monga ma alamu amoto, kuyatsa, ndi kulankhulana panthawi yadzidzidzi), zingwe zina za m'nyanja za optical fiber zimaphatikizapo wosanjikiza wosatentha moto. Zingwe zamachubu otayirira nthawi zambiri zimafunikira kuwonjezeredwa kwa tepi ya mica kuti zithandizire kukana moto. Zingwe zosagwira moto zimatha kukhalabe ndi kulumikizana kwanthawi yayitali pamoto, zomwe ndizofunikira kwambiri kuti zombo zitetezeke.
(6) Kulimbikitsa Mamembala
Kupititsa patsogolo mphamvu zamakina a zingwe zam'madzi zamadzimadzi, zolimbikitsa zapakati monga mawaya achitsulo a phosphated kapena pulasitiki yolimba (Mtengo wa FRP) amawonjezedwa. Izi zimawonjezera mphamvu ya chingwe ndi kukana kwamphamvu, kuonetsetsa bata pakuyika ndi kugwiritsa ntchito. Kuphatikiza apo, mamembala othandizira othandizira monga ulusi wa aramid amatha kuwonjezeredwa kuti chingwecho chikhale cholimba komanso kuti chisawonongeke ndi mankhwala.
(7) Kusintha Kwamapangidwe
Ndi kupita patsogolo kwaukadaulo, kapangidwe kake ndi zida za zingwe zam'madzi za optical fiber zikusintha mosalekeza. Mwachitsanzo, zingwe zowuma zonse zowuma zimachotsa gel otsekereza madzi ndikugwiritsa ntchito zida zotchingira madzi owuma pamachubu otayirira komanso pachimake cha chingwe, zomwe zimapereka zabwino zachilengedwe, zopepuka, komanso zabwino zopanda gel. Chitsanzo china ndikugwiritsa ntchito thermoplastic polyurethane elastomer (TPU) ngati zida zakunja za jekete, zomwe zimapereka kutentha kwakukulu, kukana mafuta, kukana kwa asidi, kukana kwa alkali, kulemera kopepuka, ndi zofunikira zazing'ono zamalo. Zatsopanozi zikuwonetsa kupita patsogolo kwa kamangidwe kake ka marine optical fiber.
(8) Mwachidule
Mapangidwe a zingwe za m'madzi a optical fiber amaganizira zofunikira zapadera za malo am'nyanja, kuphatikiza kutsekereza madzi, kukana kupanikizika, kukana dzimbiri, komanso mphamvu zamakina. Kugwira ntchito kwambiri komanso kudalirika kwa zingwe zapanyanja zowoneka bwino zimawapangitsa kukhala chinthu chofunikira kwambiri pamayendedwe amakono apanyanja. Pamene ukadaulo wa panyanja ukupita patsogolo, kapangidwe kake ndi zida za zingwe zapanyanja zowoneka bwino zikupitilizabe kusinthika kuti zikwaniritse zofunikira pakufufuza mwakuya kwanyanja komanso zosowekera zovuta zolumikizirana.
Za ONE WORLD (OW Cable)
ONE WORLD (OW Cable) ndiwotsogola padziko lonse lapansi wogulitsa zida zapamwamba kwambiri zamawaya ndi zingwe. Zogulitsa zathu zimaphatikizapo pulasitiki yolimba (FRP), zida za zero-halogen (LSZH) zotsika utsi, polyethylene (HFFR PE) yopanda utsi, ndi zida zina zapamwamba zomwe zidapangidwa kuti zikwaniritse zofunikira zama chingwe amakono. Ndi kudzipereka ku zatsopano, khalidwe, ndi kukhazikika, DZIKO LIMODZI (OW Cable) lakhala bwenzi lodalirika kwa opanga zingwe padziko lonse lapansi. Kaya ndi zingwe zama fiber optical fiber, zingwe zamagetsi, zingwe zoyankhulirana, kapena zida zina zapadera, timapereka zida ndi ukatswiri wofunikira kuti tiwonetsetse kuti magwiridwe antchito ndi odalirika.
