Txheej txheem cej luam ntawm Common Outdoor Optical Cables
Raws li cov neeg nqa khoom tseem ceeb rau kev xa cov ntaub ntawv, cov kab hluav taws xob sab nraum zoov ua lub luag haujlwm tseem ceeb hauv ntau hom kev thov. Lawv feem ntau muab faib ua ob hom: lub hauv paus raj - hom cables thiab txheej - cov hlua khi. Ob qho qauv no nthuav tawm cov yam ntxwv ntawm kev ua tau zoo thiab tsim nyog rau qhov chaw sib txawv thiab cov kev xav tau.
Central Tube-Hom Optical Cables
Tube khoom thiab cov qauv
Lub raj ntawm lub hauv paus raj- hom cables yog tsim los ntawm cov khoom siv PBT, uas sib xyaw ua ke nrog kev yooj yim los tiv thaiv lub siab sab nraud. Txawm li cas los xij, qee lub tuam txhab me me tuaj yeem xaiv qhov qis dua - cov khoom siv PP tus nqi hloov pauv rau PBT, uas tuaj yeem cuam tshuam kev tiv thaiv fiber ntau thaum thauj thiab teeb tsa. PP cov ntaub ntawv zoo li semi-translucent, pom qhov txawv ntawm PBT cov ntaub ntawv.
Fiber Coloring thiab xim -Lock Technology
Hauv kev sib txuas lus engineering, cov xim yas yog extruded mus rau txhua qhov fiber ntau hauv cov cable kom paub qhov txawv ntawm tus kheej cores. Cov txheej txheem xim no suav nrog kev siv cov xim sib txawv rau txhua qhov liab qab fiber ntau hauv cov kab hluav taws xob sab nraum zoov, suav nrog 12 xim txheej txheem raws li Ministry of Information Industry tus qauv xim spectrum. Tsis tas li ntawd, txhawm rau tiv thaiv cov fibers ntxiv, lawv qhov chaw yog coated nrog 250-micron txheej ntawm translucent resin. Qhov xim-locking fiber ntau tshuab yog ua haujlwm nyob rau hauv qee qhov txawv teb chaws fiber ntau cov txheej txheem. Thaum nws tshem tawm cov kauj ruam xim, nws tuaj yeem txwv kev hloov pauv thaum lub sij hawm faib fiber ntau.
Dej-Cov ntaub thaiv npog thiab tsis yog-Woven Fabric
Cov dej- thaiv daim kab xev yog ib qho tseem ceeb hauv kev tsim kho qhov muag cable, muaj ob txheej ntawm cov ntaub ntawv uas tsis yog -woven npuag sandwiching dej- nqus hmoov. Thaum cov dej nkag mus rau hauv cable, cov hmoov sai sai nqus cov dej noo thiab nthuav dav, tsim cov gel-zoo li cov khoom uas tiv thaiv dej nkag mus rau hauv cable. Txawm li cas los xij, qee cov tuam txhab lag luam tuaj yeem hloov cov dej- thaiv daim kab xev nrog qis dua -tus nqi tsis yog- ntaub npuag los txo cov nuj nqis. Cov kev hloov pauv no tsis tuaj yeem muab cov dej thaiv zoo thaum lub cable sab nrauv puas lawm.
Cov khoom siv txhawb zog thiab lwm yam khoom siv
Optical cables suav nrog corrugated steel daim kab xev, feem ntau txhawm rau txhim kho lub zog sab nraud thiab tensile lub zog thaum tiv thaiv nas kev puas tsuaj thiab tiv thaiv lub raj ntim. Tsis tas li ntawd, ob qho tib si steel hlau txuas ntxiv txhawb lub zog tensile lub zog. Cov xov hlau no tau txais kev kho tshwj xeeb xws li phosphating lossis galvanizing los tiv thaiv xeb.
Sheath Materials thiab cov nqi txiav txim siab
Cov kab hluav taws xob sab nraum zoov feem ntau siv nruab nrab- ntom polyethylene (MDPE) raws li cov ntaub qhwv, txawm hais tias qee tus neeg siv khoom tuaj yeem hais qhia siab - ntom polyethylene (HDPE). Thaum HDPE nce nqi, nws muaj lub cev zoo dua. Qee qhov kev txiav txim kuj tseem yuav xav tau qis- pa taws, xoom-halogen (LSZH) cov ntaub ntawv rau lub hnab. Txawm li cas los xij, txhawm rau txo cov nqi, qee cov tuam txhab lag luam yuav xaiv siv cov khoom siv rov ua dua tshiab rau cable sheath. Thaum qhov no txo cov nuj nqis, nws yuav ua rau muaj teeb meem xws li qhov tsis zoo, qhov ntxhib ntxhib ntxhib los mos, impurity contamination, thiab susceptibility to cracking and water ingress.
Txheej - Stranded Optical Cable
Txheej - Stranded Optical Cable Structure
Txheej -stranded optical cables ua tau zoo dua lub zog thiab dej / noo noo los ntawm nruj braiding ntau fiber ntau- cov hlab ntim ib ncig ntawm lub hauv paus muaj zog cov tswv cuab. Cov hom muaj xws li GYTS thiab GYTA. Cov qauv no tso cai rau kev sib xyaw ua ke ntawm cov raj xoob los tsim cov cables nrog ntau cov fiber ntau suav.
GYTA vs. GYTS Sib piv
GYTA thiab GYTS yog ob qho tib si stranded optical cables. Tus qauv GYTS nta ntau lub raj twisted nyob ib ncig ntawm cov hlau phosphated tuab, nrog dej - thaiv cov kab sib txuas sau cov khoob hauv cov kab sib tw. GYTA cables siv aluminium daim kab xev es tsis txhob steel daim kab xev. Txawm hais tias muaj peev xwm ua tsis tau zoo me ntsis hauv kev ua haujlwm siab sab nraud, lawv muaj kev ua haujlwm zoo dua rustproofing thiab noo noo barrier kev ua tau zoo, ua rau lawv haum rau qhov chaw ib puag ncig.
GYFTY Optical Cable
GYFTY cable yog tus cwj pwm los ntawm nws qhov kev txhawb zog thiab kev tiv thaiv dej. Nws tshwj xeeb stranding tsim thiab cable compound filling ua rau nws haum rau ntau haiv neeg ib puag ncig xws li aerial thiab ncaj faus daim ntaub ntawv. Txhawm rau txhim kho lub zog tensile hauv kev teeb tsa dav hlau, cov tuam txhab tsim cov aramid fibers nyob ib ncig ntawm cov tub ntxhais uas tso tseg.
Lwm Txheej -Twisted Structures
Cov txheej txheem ntxiv -twisted cable configurations muaj xws li ADSS thiab OPGW hom. ADSS cables suav nrog txheej txheej txheej aramid uas npog los ntawm lub tsho, thaum OPGW cables tsev fibers hauv txhuas raj. Cov hlab no tau twisted nrog cov hlau xaim los ua kom muaj zog tag nrho -cov qauv hlau, hais txog kev muaj peev xwm tiv thaiv xob laim.
