Daim ntawv thov
OPGW Fiber Optic Cable, uas feem ntau yog siv rau hauv lub zog hluav taws xob, tau teeb tsa hauv qhov chaw nyab xeeb tshaj plaws ntawm cov kab sib kis.Nws "shields" tag nrho cov tseem ceeb conductors los ntawm xob laim ntaus thiab muab ib tug kev sib txuas lus txoj kev rau kev sib txuas lus sab hauv thiab sab nraud.
Lub fiber optic hauv av cable muaj ob txoj haujlwm, ua rau nws muaj ob txoj haujlwm cable.Nws muaj qhov zoo ntawm cov fibers optical fibers uas yuav siv tau rau kev sib txuas lus thiab yog npaj los hloov cov pa zoo li qub / shielding / av xaim ntawm cov khoom siv hluav taws xob.
OPGW cable yuav tsum muaj peev xwm tiv taus cov neeg kho tshuab uas muaj huab cua zoo li cua thiab dej khov rau ntawm cov khoom siv hluav taws xob.Los ntawm kev muab txoj hauv kev rau hauv av yam tsis muaj kev puas tsuaj rau cov kab sib kis, OPGW kuj tseem tuaj yeem daws teeb meem hluav taws xob ntawm cov kab sib txuas.
Kev tsim kho
OPGW Fiber Optic Cable muaj ob txoj kev tsim kho:
1. Central xoob raj hom
1. Ib lub hauv paus txhuas raj uas kaw thiab dej resistant thiab ntim nrog dej thaiv gel muaj cov fibers xoob.Nyob rau hauv ib puag ncig hnyav, lub raj no tiv thaiv cov fiber ntau thaum lub sijhawm teeb tsa thiab ua haujlwm.Raws li kev xav tau ntawm engineering, lub raj stainless hlau tuaj yeem hloov pauv yog hlau nrog txhuas txheej.Nyob rau hauv lub plawv ntawm lub cable yog ib tug stainless optical raj uas yog shielded los ntawm ib los yog ntau tshaj txheej ntawm txhuas-clad steel, aluminium alloy nyob ntawm tej, los yog hlau hlau.Cov hlau xaim hlau muaj cov khoom siv hluav taws xob kom txo tau qhov kub thiab txias hauv qhov chaw luv luv thiab lub zog siv hluav taws xob kom muaj sia nyob nyuaj rau kev teeb tsa thiab kev ua haujlwm.
2.Txhua qhov kho qhov muag fiber ntau yog qhov sib txawv kom pom tseeb ntawm kev siv cov cim fiber ntau uas muaj cov xim thiab cov lej ntawm lub nplhaib ntawm nws.Qhov kev tsim qauv compact no muaj lub zog txhua yam muaj zog thiab qhov ntsuas tam sim no nyob rau hauv ib txoj kab uas hla me me.Cov kab me me kuj ua rau kev ua haujlwm zoo heev sag nro.
2.Multi xoob raj hom
Cov fibers yog muab tso rau hauv lub kaw ntom nti thiab dej resistant stainless hlau raj uas muaj dej thaiv gel.Ob los yog peb stainless hlau optical raj yog helically stranded nyob rau hauv lub puab txheej ntawm ib tug ntau-txheej cable.Cov ntau lub raj xoob hom yog tsim los rau feem ntau cov fiber ntau suav ntau tshaj 48 nrog rau qhov siab tshaj plaws fiber ntau suav txog 144. Cov ntau lub raj xoob hom tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm tus ntoo khaub lig loj thiab muaj peev xwm loj tam sim no.
Optical fiber ntau yog ua los ntawm siab ntshiab silica thiab germanium doped silica.UV curable acrylate cov ntaub ntawv yog siv rau fiber ntau cladding li optical fiber ntau tiv thaiv txheej.Cov ntaub ntawv nthuav dav ntawm kev ua haujlwm fiber ntau tau pom hauv cov lus hauv qab no.
Optical fiber siv cov cuab yeej tshwj xeeb spun ntse tswj tus nqi ntawm PMD, thiab ua kom paub tseeb tias nws tuaj yeem ua kom ruaj khov hauv cabling.
