1. Lub hau sab nraud:
1. Lub tsho sab nraud ntawm cov xov hluav taws xob sab hauv tsev feem ntau yog ua los ntawm polyvinyl chloride (PVC), polyethylene, lossis polyurethane uas tsis kub hnyiab (LSZH). Lub tsho no du, ci ntsa iab, yoog tau, thiab yooj yim rau tev tawm. Lub tsho sab nraud ntawm cov xov hluav taws xob tsis zoo muaj qhov tiav tsis zoo thiab yooj yim lo rau cov tes tsho nruj thiab cov xov aramid.
2. Lub plhaub sab nraud ntawm cov xov hluav taws xob sab nraum zoov yuav tsum ua los ntawm cov yas dub zoo (HDPE, MDPE). Thaum lub xov hluav taws xob ua tiav lawm, lub plhaub sab nraud yuav tsum du, ci ntsa iab, tuab sib npaug, thiab tsis muaj npuas. Lub plhaub sab nraud ntawm cov xov hluav taws xob qis dua feem ntau yog ua los ntawm cov khoom siv rov ua dua tshiab. Lub plhaub sab nraud ntawm cov xov hluav taws xob qis dua tsis zoo vim muaj cov khoom tsis huv (cov hmoov av) ntau hauv cov khoom siv raw, ua rau muaj ntau qhov me me hauv lub plhaub sab nraud ntawm lub xov hluav taws xob. Yog tias lub plhaub sab nraud ntawm lub xov hluav taws xob khoov ntau zaus, nws yuav puas tsuaj thiab hloov dawb. Tom qab lub xov hluav taws xob raug ntsia rau ib ntus, lub plhaub sab nraud yuav tawg thiab cia dej nkag mus.
2. Cov khoom siv fiber ntau:
Cov chaw tsim khoom siv hluav taws xob siv cov fiber Class A los ntawm cov chaw tsim khoom ua ntej. Cov cables pheej yig thiab tsis zoo feem ntau siv Class C, Class D, thiab cov fibers tsis raug cai uas tsis paub keeb kwm. Cov fibers no muaj cov peev txheej nyuaj thiab tau tawm ntawm lub Hoobkas ntev heev. Lawv feem ntau ntub thiab tsis muaj xim, thiab cov fibers multimode feem ntau sib xyaw nrog cov fibers ib hom. Cov chaw tsim khoom me me feem ntau tsis muaj cov khoom siv kuaj tsim nyog thiab tsis tuaj yeem ntsuas qhov zoo ntawm cov fibers. Cov fibers no tsis tuaj yeem pom los ntawm kev pom ib leeg. Cov teeb meem feem ntau ntsib thaum lub sijhawm tsim khoom suav nrog: bandwidth nqaim heev thiab qhov deb kis luv luv; tuab tsis sib xws, tiv thaiv kev sib txuas rau pigtail; thiab tsis muaj kev ywj pheej, ua rau cov fiber yooj yim tawg thaum lub sijhawm coiling.
3. Cov hlau hlau uas muaj zog:
Cov xov hlau hauv cov xov hlau fiber optic sab nraum zoov yog phosphated thiab muaj qhov chaw grey. Hom xov hlau no tsis ua rau hydrogen poob ntau tom qab kev teeb tsa, tsis xeb, thiab muaj lub zog tensile siab. Cov xov hlau fiber optic qis dua feem ntau yog ua los ntawm cov hlau nyias lossis txhuas. Cov no tuaj yeem txheeb xyuas los ntawm lawv cov tsos dawb thiab qhov tseeb tias lawv tuaj yeem khoov tau yooj yim thaum tuav hauv tes. Cov xov hlau fiber optic ua nrog cov xov hlau hlau no yuav tsim cov hydrogen poob ntxiv yav tom ntej, thiab dhau sijhawm, ob qhov kawg ntawm cov thawv fiber optic yuav oxidize thiab tawg.
4. Siv hlau ua los ntawm hlau:
Cov chaw tsim khoom siv cov hlau uas qhwv ntev thiab txheej nrog ob sab, txhuam, thiab yas tiv taus xeb. Cov xov hluav taws xob tsis zoo yog ua los ntawm cov hlau ib txwm muaj, thiab feem ntau tsuas yog ib sab tau kho kom tiv thaiv xeb.
5. Lub thawv fiber optic:
Lub raj xoob uas nyob ib puag ncig cov fiber ntau hauv cov cable optical yuav tsum yog ua los ntawm cov khoom siv PBT. Cov khoom siv no muaj zog heev, tiv taus kev hloov pauv, thiab tiv taus hnub nyoog. Cov tsev cable optical qis dua feem ntau yog ua los ntawm PVC. Lub cheeb tsam sab nraud ntawm cov tsev no yog nyias heev thiab mos, yooj yim flattening thaum pinched. Lawv zoo ib yam li cov straws haus dej thiab tsis muab kev tiv thaiv txaus rau cov fiber ntau.
6. Tshuaj pleev fiber:
Cov tshuaj nplaum fiber siv rau hauv cov xov hluav taws xob sab nraum zoov tuaj yeem tiv thaiv cov nyiaj tawm, hydrogen poob, thiab txawm tias cov fiber optic tawg los ntawm cov dej noo. Cov tshuaj nplaum fiber tsawg heev siv rau hauv cov xov hluav taws xob qis dua, thiab qee cov npuas dej yuav pom tau rau lub qhov muag liab qab. Xwb, cov tshuaj nplaum fiber qis dua siv, uas ua rau lub neej ntawm cov xov hluav taws xob fiber optic luv dua.
7. Aramid:
Kuj hu ua Kevlar, aramid fiber yog cov tshuaj fiber muaj zog heev uas tam sim no siv feem ntau hauv kev lag luam tub rog. Nws yog siv los tsim cov kaus mom tub rog thiab cov tsho tiv thaiv mos txwv. Tam sim no, cov aramid fiber hauv khw feem ntau yog los ntawm Asmeskas hom DuPont. Ob qho tib si sab hauv tsev thiab sab nraud fais fab (ADSS) optical cables siv cov xov aramid ua kev txhawb nqa. Vim yog tus nqi siab ntawm aramid (200,000 yuan / ton), cov xov sab hauv tsev tsis zoo feem ntau muaj lub cheeb sab nraud nyias heev, uas tuaj yeem txuag cov nqi los ntawm kev txo cov xov aramid siv. Hom optical cable no yooj yim puas thaum hla dhau conduit.
8. Cov tshuaj nplaum cable:
Cov nplaum fiber sab nraud ntawm cov cable fiber optic yog sib txuas rau sab nraud ntawm lub tes tsho fiber optic kom tiv thaiv cov cable los ntawm cov dej noo. Cov nplaum cable zoo yog sib xyaw kom sib npaug thiab tsis sib cais tom qab siv ntev. Hauv cov cable optical zoo dua, cov nplaum cable yuav ua pa lossis cov khoom sau yuav tsis txaus, cuam tshuam rau kev ua haujlwm tiv thaiv dej noo ntawm cov cable.
