1. Kodi Optical Fiber ndi chiyani?
Optical fiber imakhala ndi magalasi osinthika kapena zingwe zapulasitiki zopangidwa kuti zizipereka kuwala. Opanga amapanga ulusi umenewu pogwiritsa ntchito njira zitatu: kupanga preform, kujambula, ndi kupaka.
Ma fiber optics amapereka bandwidth apamwamba komanso mtunda wautali wotumizira kuposa zingwe zamkuwa zamkuwa.
Chifukwa amatumiza ma pulses a kuwala m'malo mwa mafunde amagetsi, minyewayi imatetezedwa kwathunthu electromagnetic kusokoneza (Emu).
Izi zimapangitsa kuwala kwa fiber kukhala njira yodziwika bwino yolumikizirana matelefoni akutali, data center, ndi Mtengo wa FTT kutumiza.
2. Zida Zomwe Zimagwiritsidwa Ntchito mu Optical Fibers
Silica Glass Fibers
Ma network a telecommunication amadalira pafupifupi ulusi wagalasi wa silika.
- Kuyera Kwambiri: Magalasi a silika amapereka kutsika kotsika kwambiri. Izi zimalola kufalitsa chizindikiro chakutali ndi kutayika kochepa kwa deta.
- Thermal ndi Chemical Resistance: Silika imapirira kutentha kwambiri ndipo imalimbana ndi dzimbiri. Mainjiniya amafotokozera silika kwa nkhanza zakunja, mafakitale, ndi malo apansi pamadzi.
- Core Versatility: Opanga amajambula silika munjira imodzi (kawirikawiri 9µm pachimake) ndi unyimo (50µm kapena 62.5µm pachimake) masinthidwe kuti akwaniritse zofunikira za bandwidth ya netiweki.
Plastic Optical Fibers (POF)
POF imagwiritsa ntchito zida za polima, monga PMMA, m'malo mwa galasi. Akatswiri amafotokozera POF mwachindunji, ntchito zakutali.
Mtengo wothandiza: Zida za POF ndi ma transceivers omwe amalumikizana nawo amawononga ndalama zochepa kwambiri kuposa makina opangidwa ndi silika.
Kukula Kwakukulu Kore: POF nthawi zambiri imakhala ndi 1mm pachimake. Kukula kwakukuluku kumathandizira kuyanika kowunikira komanso kumachepetsa nthawi yoyimitsa.
Kusinthasintha Kwambiri: Zomangamanga za pulasitiki zimagwira zolimba bend radii popanda kusweka. Izi zimapangitsa POF kukhala yabwino kwa malo ocheperako ngati ma waya amagalimoto kapena maukonde apanyumba.
3. Kapangidwe ka Fiber Optic Cable
Chingwe chathunthu cha fiber optic patch chimakhala ndi ulusi wopanda kanthu wotetezedwa ndi zigawo zingapo..
- Kwambiri: The central transmission medium. Wopangidwa ndi galasi la silika la ultra-pure, imanyamula mphamvu ya kuwala kwa kuwala.
- Kuyika: Galasi yachiwiri yozungulira pachimake. Ili ndi index yotsika pang'ono ya refractive, zomwe zimakakamiza kuwala kuwonekeranso mkatikati mwa kuwonetsera kwathunthu kwamkati.
- Kupaka: Gawo loyamba la chitetezo, Nthawi zambiri, acrylate amachiritsidwa ndi UV. Imatchinjiriza galasi lopanda kanthu ku tizikwangwala tating'ono komanso chinyezi mukamagwira.
- Mphamvu Mamembala: Ulusi wa Aramid (monga Kevlar®) kuzungulira ulusi wophimbidwa. Izi zimapereka mphamvu zolimba kuti ziteteze pachimake chagalasi panthawi yokoka chingwe.
- Jacket Yakunja: Mchimake wakunja, Kawirikawiri amachotsedwa ku PVC, Mtengo wa LSZH (Utsi Wotsika Zero Halogen), kapena PE (Polyethylene). Zimateteza zigawo zamkati kuti zisawonongeke zachilengedwe.
- Contral: The kuthupi kuthetsa mfundo. Zolumikizira zimagwiritsa ntchito ma ferrule a ceramic olondola kuti agwirizane bwino ndi ma fiber cores kuti atayike pang'ono.
4. Galasi vs. Pulasitiki Fiber Optics
Kugwiritsa Ntchito Glass:
- Zakuthupi: Silika yoyera kwambiri.
- Kukhalitsa: Kukhalitsa kwapamwamba ndi kutayika kochepa kwa chizindikiro pa mtunda wautali.
- Mtengo: Zokwera mtengo kuposa chingwe chapulasitiki cha fiber optic.
Kugwiritsa Ntchito Pulasitiki:
- Zakuthupi: Ma polima ngati acrylate ndi polyimide.
- Kusinthasintha: Zambiri zosinthika komanso zosavuta kukonza.
- Mtengo: Zotsika mtengo koma zimafunikira kusinthidwa pafupipafupi chifukwa cha mphamvu zochepa komanso index yotsika kwambiri ya refractive, kuwapanga kukhala osayenera kufalitsa deta mtunda wautali.
Glass fiber optics imapereka magwiridwe antchito apamwamba komanso olimba pakutumiza mtunda wautali, pamene pulasitiki CHIKWANGWANI Optics amapereka kusinthasintha ndi mtengo-mwachangu pa mtunda waufupi.
Kumvetsetsa magawowa komanso kusiyana kwazinthu kumathandizira kusankha njira yoyenera ya fiber optic pazosowa zanu.
5. Njira Yopangira Ma Fiber Optic
Kupanga bare optical fiber kumafuna kuwongolera kolondola kwamankhwala ndi makina. Njirayi ikutsatira magawo atatu akuluakulu:
- Coating Application: Chingwe chokokedwa chatsopanocho chisanakhudze chilichonse cholimba, imadutsa mu kapu yokutira. Nyali za UV nthawi yomweyo zimachiritsa zokutira zamitundu iwiri za polima pagalasi. Izi zimasindikiza ulusiwo ndipo zimapereka chitetezo chamakina nthawi yomweyo.
- Preform Fabrication: Amisiri amapanga olimba, cylindrical galasi ndodo yotchedwa preform. Preform iyi ili ndi mbiri yeniyeni ya refractive index ya ulusi womaliza, wakulitsidwa kukula.
- Njira Yojambula: Oyendetsa amanyamula preform munsanja yojambulira ndikutenthetsa mpaka pafupifupi 2,000 ° C. Pamene galasi limasungunuka, mphamvu yokoka imakokera pansi kukhala mosalekeza, chingwe cha microscopic. Ma micrometer a laser amawunika ulusi kuti ukhale ndi mainchesi 125µm akunja.
Kwa odalirika, ntchito zapamwamba zingwe za fiber optic, tiuzeni kuti mumve zambiri komanso mawu ofulumira.
