      Qhagamshelana nathi

      IiNkcazo zePreform

      Preform Imilinganiselo

      Imilinganiselo yepreform iya kuba njengakuLuhlu 1.1 ngezantsi.

      Itheyibhile 1.1 Preform Dimensions

      Into Iimfuno Phawula
      1 I-Avareji yeDayimitha yePreform (OD) 135 ~ 160 mm (Qaphela 1.1)
      2 Ubuninzi beDayamitha yePreform (ODmax) ≤ 160 mm
      3 Ubuncinci beDayimitha yePreform (ODmin) ≥ 130 mm
      4 Ukunyamezela kwe-OD (ngaphakathi kwe-Preform) ≤ 20 mm (kwindawo ethe ngqo)
      5 Preform Ubude (kubandakanya indawo yokubamba) 2600 ~ 3600 mm (Qaphela 1.2)
      6 Ubude obusebenzayo ≥ 1800 mm
      7 Taper ubude ≤ 250 mm
      8 I-diameter ekupheleni kwe-taper ≤ 30
      9 Preform Non-setyhula ≤ 1%
      10 Imposiso yoxinaniso ≤ 0.5 μm
      11 Imbonakalo (Qaphela 1.4&1.5)

      Qaphela 1.1: I-diameter ye-preform iya kulinganiswa ngokuqhubekayo kwindawo ethe tye kunye ne-10mm interval yi-Laser Diameter Measurement System kwaye ichazwe njengomyinge wamaxabiso alinganisiweyo. Inxalenye yeTaper iya kuchazwa njengendawo phakathi kuka-A ukuya ku-B. Icandelo elithe tye liya kuchazwa njengendawo phakathi kwe-B ukuya ku-C. A yindawo ekupheleni kwe-preform. B yindawo yokuqala enondoqo osebenzayo. C yindawo yokugqibela enondoqo osebenzayo. D licala lokugqibela le-preform.
      Qaphela i-1.2: "Ubude be-Preform" buya kuchazwa njengoko kuboniswe kwi-Figure 1.1.
      Qaphela 1.3: ICandelo eliSebenzayo liya kuchazwa njengendawo phakathi kuka-B ukuya ku-C.
      Ubude obuHlawulwayo = Ubude obusebenzayo - ∑Ubude obungasetyenziswayo kwisiphene (LUD)

      Umfanekiso 1.1 Ubume bePreform

      Inkqubo ye-OVD

      Qaphela 1.4: Amaqamza kummandla wangaphandle wogqume (jonga umfanekiso 1.2) uya kuvunyelwa, kuxhomekeke kubungakanani; inani lamaqamza ngeyunithi nganye yomthamo aliyi kudlula ezi zichazwe kwiTheyibhile 1.2 ngezantsi.

      Umzobo 1.2 Umbono we-Cross-sectional we-Preform

      Inkqubo ye-OVD2

      Qaphela i-1.5: Ukuba kukho naziphi na iziphene, ezichazwe ngezantsi, kummandla ongundoqo kunye / okanye ummandla ongaphandle we-cladding, ummandla ogubungela i-3 mm ukusuka kwicala ngalinye lesiphene uya kuchazwa njengenxalenye engasetyenziswanga (Umfanekiso 1.3). Kule meko, ubude obusebenzayo buya kuchazwa ngaphandle kobude benxalenye engasebenzisekiyo. Inxalenye engasebenzisekiyo iya kuboniswa ngu “Defect MAP”, eya kuthi iqhotyoshelwe kwiphepha lokuhlola.
      Iziphene:
      1. iqamza elikhulu kune-2 mm kumgquba wangaphandle,
      2. Iqela lamaqamza ambalwa kumgqubuthelo wangaphandle,
      3. iqamza kwindawo engaphakathi okanye embindini,
      4. into yangaphandle kwi-preform,

      Inkqubo ye-OVD3

      Ubunzima obuhlawulelwayo

      Ubunzima obuhlawulelwayo buya kubalwa ngolu hlobo lulandelayo;
      Ubunzima obuhlawulelwayo[g] ＝Ubunzima bubonke bepreform－Abukho ubunzima obusebenzayo kwindawo yetaper kunye nokubamba indawo－Ubunzima obunesiphene
      1. Ubunzima bubonke be-preform bubunzima obuvavanywa zizixhobo.
      2. " Akukho bunzima obusebenzayo kwi-taper part kunye ne-handle part" lixabiso eliqingqiweyo elinqunywe ngamava.
      3. Ubunzima besiphako ＝ Umthamo wesiphene inxalenye[cm3]) × 2.2[g/cm3]; “2.2[g/cm3]” bubuninzi beglasi yequartz.
      4. "Umthamo wenxalenye yesiphene" ＝ (OD[mm]/2)2 ×Σ(LUD)×π; LUD =Ubude obungasetyenziswayo kwisiphene=Isiphene Ubude+ 6[mm].
      5. Idayamitha ye-preform iya kulinganiswa ngokuqhubekayo kwinxalenye ethe tye kunye nekhefu le-10mm yiNkqubo yokuLinganisa i-Laser Diameter.

      IiNgcaciso zeFayibha ekujoliswe kuzo

      Xa iimeko zokudweba kunye neemeko zokulinganisa zilungile kwaye zizinzile, i-preforms iya kulindeleka ukuba ihlangabezane neenkcukacha zefiber ekujoliswe kuzo njengoko kuboniswe kwiThebhile 2.1.

      Qaphela i-2.1: I-attenuation kwi-1383 nm emva kovavanyo lokuguga kwe-hydrogen ayiyi kufakwa kwiThebhile 2.1 kuba ixhomekeke kakhulu kwiimeko zokudweba i-fiber.

      Qaphela i-2.2: Ukuqinisekisa umlinganiselo wokuphuma kwe-G.657.A1 fiber, iimeko zokudweba kufuneka zilawulwe ngokufanelekileyo ukwenza i-fiber cut-off wavelength ngaphezu kwe-1270 nm. Ubude bentambo yokusika intambo kufuneka ivavanywe xa ifayibha cutoff wavelength inkulu kune-1300nm.
