Cov qauv tub ntxhais tuaj yeem yog ib lub tub ntxhais (khoom khov thiab raj) lossis ntau lub tub ntxhais (hom tiaj thiab hom sib koom ua ke). Cov txheej tiv thaiv sab nraud tuaj yeem yog hlau lossis tsis yog hlau.
2. Kev sib xyaw ntawm Aramid Fiber hauv Optical Cables
Los ntawm sab hauv mus rau sab nraud, lub xov tooj optical muaj xws licov khoom siv fiber ntau, lub raj xoob, txheej rwb thaiv tsev, thiab lub plhaub. Lub raj xoob nyob ib puag ncig lub fiber ntau optical, thiab qhov chaw nruab nrab ntawm lub fiber ntau optical thiab lub raj xoob yog puv nrog gel. Lub txheej rwb thaiv tsev yog ua los ntawm aramid, thiab lub plhaub sab nraud yog lub plhaub polyethylene uas tsis muaj pa luam yeeb tsawg, tsis muaj halogen, uas npog lub txheej aramid.
3. Daim Ntawv Thov ntawm Aramid Fiber hauv Optical Cables
(1) Cov Cables Optical Sab Hauv Tsev
Cov xov hluav taws xob mos mos ib leeg thiab ob leeg yog cov uas muaj bandwidth siab, ceev ceev, thiab tsis poob ntau. Lawv siv dav hauv cov chaw khaws ntaub ntawv, chav server, thiab cov ntawv thov fiber-to-the-desk. Hauv cov tes hauj lwm mobile broadband uas siv ntau, ntau lub chaw nres tsheb thiab cov kab ke sib cais hauv tsev yuav tsum siv cov xov hluav taws xob ntev thiab cov xov hluav taws xob micro-optical hybrid. Txawm hais tias nws yog cov xov hluav taws xob mos mos ib leeg lossis ob leeg lossis cov xov hluav taws xob ntev thiab cov xov hluav taws xob micro-optical hybrid, kev siv cov khoom siv muaj zog, modulus siab, thiab yooj ywm.cov fiber aramidua cov khoom siv txhawb nqa kom ntseeg tau tias muaj kev tiv thaiv tshuab, hluav taws kub, kev tiv thaiv ib puag ncig, thiab ua raws li cov kev cai cable.
(2) All-Dielectric Self-Supporting (ADSS) Optical Cable
Nrog kev loj hlob sai hauv Tuam Tshoj txoj kev tsim kho vaj tse fais fab thiab cov haujlwm ultra-high-voltage, kev sib koom ua ke ntawm cov tes hauj lwm sib txuas lus fais fab nrog 5G thev naus laus zis yog qhov tseem ceeb rau kev tsim kho smart grid. ADSS optical cables siv raws cov kab hluav taws xob, xav kom lawv ua haujlwm zoo hauv cov chaw muaj hluav taws xob siab, txo qhov hnyav ntawm cov cable kom txo qhov hnyav ntawm cov ncej hluav taws xob, thiab ua tiav kev tsim qauv dielectric tag nrho los tiv thaiv xob laim thiab xyuas kom muaj kev nyab xeeb. Cov fibers aramid muaj zog, modulus siab, coefficient qis ntawm kev nthuav dav tiv thaiv cov fibers optical hauv ADSS cables.
(3) Cov Cables Optoelectronic Composite uas txuas nrog
Cov xov hlau txuas yog cov khoom tseem ceeb uas txuas cov platform tswj thiab cov khoom siv tswj xws li cov npas, cov dav hlau, lossis cov drones. Hauv lub caij nyoog ntawm cov ntaub ntawv ceev ceev, kev siv digital, thiab kev txawj ntse, cov xov hlau sib txuas optoelectronic composite tether yuav tsum muab ob qho tib si lub zog hluav taws xob thiab kev xa cov ntaub ntawv ceev ceev rau cov khoom siv system.
