Mafunso omwe amafunsidwa pafupipafupi pazingwe za fiber optic:
1, Kodi chingwe chogwetsera ulusi chimawononga ndalama zingati?
Nthawi zambiri, mtengo pa chingwe cha fiber optic chimachokera ku $ 30 mpaka $ 1000, kutengera mtundu ndi kuchuluka kwa ulusi: G657A1/G657A2/G652D/OM2/OM3/OM4/OM5, zinthu za jekete PVC/LSZH/PE, kutalika, ndi kapangidwe kamangidwe. ndi zinthu zina zimakhudza mitengo ya zingwe zotsika.
2, Chifunirozingwe za fiber optickuonongeka?
Zingwe za fiber optic nthawi zambiri zimagawidwa ngati zosalimba, monga galasi.Zoonadi, fiber ndi galasi.Ulusi wagalasi wa zingwe za fiber optic ndi wosalimba, ndipo pamene zingwe za fiber optic zimapangidwa kuti ziteteze ulusi, zimakhala zosavuta kuwonongeka kusiyana ndi waya wamkuwa.Chowonongeka kwambiri ndi kusweka kwa ulusi, komwe kumakhala kovuta kuzindikira.Komabe, ulusi umathanso kuthyoka chifukwa cha kupsinjika kwambiri pokoka kapena kuswa.Kodi zingwe za fiber optic zidzawonongeka Zingwe za fiber optic nthawi zambiri zimawonongeka m'njira ziwiri:
• Zingwe zopangira zida za fiber optic zitha kuwononga zolumikizira ngati pamizidwa kwambiri pakuyika.Izi zikhoza kuchitika pamene zingwe zazitali za fiber optic zidutsa mu ngalande zothina kapena ngati zingwe za fiber optic zikamamatira.
• Chingwe cha fiber optic chinadulidwa kapena kuthyoledwa panthawi yogwira ntchito ndipo chiyenera kulumikizidwanso kuti chilumikizidwenso.
3, Kodi ndingadziwe bwanji ngati chingwe changa cha fiber chawonongeka?
Ngati mutha kuwona magetsi ofiira ambiri, cholumikizira ndi chowopsa ndipo chiyenera kusinthidwa.Cholumikizira ndi chabwino ngati muyang'ana kumapeto kwina ndikungowona kuwala kuchokera ku ulusi.Si bwino ngati ferrule yonse ikuyaka.OTDR imatha kudziwa ngati cholumikizira chawonongeka ngati chingwecho chili chotalika mokwanira.
4, Momwe Mungasankhire Zingwe za Fiber Optic zochokera pa Bend Radius?
Kupindika kwa chingwe cha fiber optic ndikofunikira pakuyika.Zinthu zomwe zimakhudza utali wocheperako wa chingwe cha fiber optic ndi makulidwe a jekete yakunja, ductility zakuthupi, ndi mainchesi apakati.
Kuti titeteze kukhulupirika ndi ntchito ya chingwe, sitingathe kuipinda mopitirira malire ake ovomerezeka.Nthawi zambiri, ngati bend radius ndiyodetsa nkhawa, tikulimbikitsidwa kuti ma bend-insensitive fiber azitha kuyendetsa chingwe mosavuta ndikuchepetsa kutayika kwa ma sign ndi kuwonongeka kwa chingwe chingwe chikapindika kapena kupindika.Pansipa pali tchati cha bend radius.
Mtundu wa Fiber Cable
Minimum Bend Radius
G652D
30 mm
G657A1
10 mm
G657A2
7.5 mm
B3
5.0 mm
5, Kodi kuyesa CHIKWANGWANI chamawonedwe chingwe?
Tumizani chizindikiro cha kuwala mu chingwe.Pochita izi, yang'anani mosamala mbali ina ya chingwe.Ngati kuwala kwapezeka pachimake, zikutanthauza kuti CHIKWANGWANI sichinaswe, ndipo chingwe chanu ndi choyenera kugwiritsidwa ntchito.
6, Kodi zingwe za fiber zimafunika kusinthidwa kangati?
Kwa zaka pafupifupi 30, pazingwe zoyikidwa bwino, kuthekera kwa kulephera mu nthawi yotere kumakhala pafupifupi 1 pa 100,000.
Poyerekeza, mwayi woti anthu alowererepo (monga kukumba) kuwononga ulusi ndi pafupifupi 1 pa 1,000 nthawi yomweyo.Choncho, pansi pa zikhalidwe zovomerezeka, ulusi wapamwamba kwambiri wokhala ndi teknoloji yabwino ndikuyika mosamala uyenera kukhala wodalirika kwambiri - malinga ngati sunasokonezedwe.
7, Kodi nyengo yozizira idzakhudza zingwe za fiber optic?
Kutentha kukatsika pansi pa ziro ndipo madzi n’kuundana, madzi oundana amaundana mozungulira ulusiwo, zomwe zimapangitsa kuti ulusiwo upunduke ndi kupindika.Izi zimachepetsa chizindikiro kudzera mu ulusi, osachepera kuchepetsa bandwidth koma makamaka kuyimitsa kufalitsa deta palimodzi.
8, Ndi mavuto ati awa omwe angapangitse kutayika kwa chizindikiro?
Zifukwa zodziwika kwambiri za kulephera kwa fiber:
• Kusweka kwa ulusi chifukwa cha kupsinjika kwa thupi kapena kupindika kwambiri
• Kusakwanira kufalitsa mphamvu
• Kutayika kwakukulu kwa chizindikiro chifukwa cha zingwe zazitali
• Zolumikizira zoyipitsidwa zimatha kuyambitsa kutayika kwa ma siginecha mochulukira
• Kutayika kwakukulu kwa chizindikiro chifukwa cha kulephera kwa cholumikizira kapena cholumikizira
• Kutayika kwakukulu kwa chizindikiro chifukwa cha zolumikizira kapena zolumikizira zambiri
• Kulumikizika kolakwika kwa ulusi pa patch panel kapena tray splice
Nthawi zambiri, ngati kulumikizana kulephera kwathunthu, ndichifukwa choti chingwe chasweka.Komabe, ngati kulumikizana kuli kwakanthawi, pali zifukwa zingapo:
• Kuchepetsa kwa chingwe kungakhale kokwezeka kwambiri chifukwa cha zolumikizira zabwino kwambiri kapena zolumikizira zambiri.
• Fumbi, zidindo za zala, zokanda, ndi chinyezi zimatha kuwononga zolumikizira.
• Mphamvu zotumizira mauthenga ndizochepa.
• Kusalumikizana bwino mu chipinda cha mawaya.
9, Kodi chingwecho chimakwiriridwa bwanji?
Kuzama kwa Chingwe: Kuzama komwe zingwe zokwiriridwa zitha kuyikidwa zimasiyana malinga ndi momwe zinthu ziliri, monga "mizere yowuma" (kuzama komwe nthaka imaundana chaka chilichonse).Ndikoyenera kukwirira zingwe za fiber optic mozama/kuphimba pafupifupi mainchesi 30 (77 cm).
10, Kodi kupeza zingwe zokwiriridwa kuwala?
Njira yabwino yopezera chingwe cha fiber optic ndikuyika mtengo wa chingwe mu ngalande, kenako gwiritsani ntchito chipangizo cha EMI kuti mulumikize mwachindunji pamtengo wa chingwe ndikutsata chizindikirocho, chomwe, ngati chichitidwa molondola, chingapereke malo olondola kwambiri.
11, Kodi zowunikira zitsulo zimatha kupeza zingwe zowunikira?
Monga tonse tikudziwira, mtengo wowononga zingwe za fiber optic zamoyo ndiwokwera.Nthawi zambiri amanyamula mauthenga ochuluka kwambiri.Ndikofunikira kupeza malo ake enieni.
Tsoka ilo, zimakhala zovuta kupeza ndi masikani apansi.Sizitsulo ndipo sangagwiritse ntchito chitsulo chokhala ndi chingwe cholowera.Nkhani yabwino ndiyakuti nthawi zambiri amasonkhanitsidwa pamodzi ndipo amatha kukhala ndi zigawo zakunja.Nthawi zina, zimakhala zosavuta kuziwona pogwiritsa ntchito masikeni olowera pansi pa radar, zolozera ma chingwe, kapenanso zowunikira zitsulo.
12, Kodi chubu cha buffer mu chingwe cha kuwala ndi chiyani?
Machubu a buffer amagwiritsidwa ntchito mu zingwe za fiber optic kuteteza ulusi kuti zisasokonezedwe ndi ma sign ndi zinthu zachilengedwe, monga momwe amagwiritsidwira ntchito panja.Machubu a buffer amatchinganso madzi, omwe ndi ofunikira kwambiri pamapulogalamu a 5G chifukwa amagwiritsidwa ntchito panja ndipo nthawi zambiri amakumana ndi mvula ndi matalala.Ngati madzi alowa mu chingwe ndikuundana, amatha kufalikira mkati mwa chingwe ndikuwononga ulusi.
13, Kodi zingwe za fiber optic zimalumikizidwa bwanji pamodzi?
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 ulusi wamaso awiri kapena kuposa omwe amalumikizana ndikuyika zigawo zomwe zimapangitsa kuti ulusiwo ukhale wogwirizana 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 kugwirizanitsa mbali ziwiri za ulusi, ndiyeno magalasi amatha "kusakanikirana" kapena "kuwotcherera" pamodzi pogwiritsa ntchito arc yamagetsi kapena kutentha.
Izi zimapanga kulumikizana kowonekera, kosawoneka bwino, komanso kosalekeza pakati pa ulusi, zomwe zimapangitsa kuti pakhale kutayika kochepa kwambiri 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.
