Yuav ua li cas txheeb xyuas fiber ntau optic cable
Txhawm rau kom ntseeg tau qhov zoo ntawm cov khoom siv kho qhov muag, cov kev ntsuam xyuas feem ntau yog ua thaum lub sijhawm thiab tom qab kev tsim khoom. Cov kev ntsuam xyuas no ntsuas qhov kho qhov muag, kho qhov muag, thiab ib puag ncig tus yam ntxwv ntawm cable los lav tias nws ua tau raws li cov qauv kev ua haujlwm. Ntawm no yog ib tug txheej txheem cej luam ntawm cov txheej txheem tseem ceeb siv los soj ntsuam kho qhov muag cable zoo:
1. Kev tshwm sim
• Ua ib qho kev soj ntsuam ntawm qhov pom ntawm qhov pom ntawm qhov muag cable. Xyuas seb qhov kho qhov muag cable puas tiav, tsis muaj kev puas tsuaj rau lub cev lossis khoov. Yog tias muaj cov kab nrib pleb, hnav, deformation thiab lwm yam teeb meem ntawm cov tawv nqaij sab nraud ntawm cov kab hluav taws xob kho qhov muag, nws yuav cuam tshuam rau kev sib kis ntawm cov khoom siv kho qhov muag.
• Tshawb xyuas seb cov txheej txheem ntawm cov khoom siv kho qhov muag puas ua tau raws li qhov yuav tsum tau ua. Tshawb xyuas seb lub taub sab nraud, qhov loj me, qhov tuab, lub tes tsho loj, thiab tus naj npawb ntawm cov fiber ntau ntawm cov khoom siv kho qhov muag puas tsim nyog.
2. Optical Performance Tests
• Kev Ntsuas Attenuation: Ntsuas cov teeb liab poob hauv qhov kho qhov muag fiber ntau dhau ib qhov deb. Qhov no feem ntau yog ua los ntawm Optical Time-Domain Reflectometer (OTDR), uas pab txheeb xyuas cov theem ntawm cov teeb liab degradation thiab pinpoint qhov tsis xws luag xws li khoov lossis tawg hauv fiber ntau.
• Chromatic Dispersion Test: Ntsuam xyuas seb qhov sib txawv wavelengths ntawm lub teeb mus los ntawm fiber ntau. Ntau chromatic dispersion tuaj yeem ua rau lub teeb liab distortion, tshwj xeeb tshaj yog nyob deb.
• Polarization Mode Dispersion (PMD) Test: Ntsuas qhov sib txawv ntawm kev nthuav tawm ceev ntawm cov hom polarization sib txawv, uas tuaj yeem ua rau muaj teeb meem kev xa cov ntaub ntawv. Tsawg PMD yog qhov tseem ceeb rau kev sib txuas lus ceev ceev.
3. Kev Ntsuas Kev Ua Haujlwm Zoo
• Tensile Strength Test: Ua kom cov kab hluav taws xob kho qhov muag tuaj yeem tiv taus cov rub tawm thaum lub sijhawm teeb tsa. Qhov kev sim no siv qhov nro rau cable thiab ntsuas nws qhov tawg.
• Crush Resistance Test: Txiav txim siab ntau npaum li cas lub cable tuaj yeem tiv taus ua ntej nws puas. Qhov kev ntsuam xyuas no ua kom lub cable nyob twj ywm yog tias raug rau sab nraud quab yuam, xws li compression thaum lub sij hawm installation.
• Bending Test: Ntsuas lub peev xwm ntawm lub cable kom tiv taus kev khoov dua tshiab yam tsis muaj kev puas tsuaj. Optical cables yuav tsum muaj kev ua tau zoo txawm tias tom qab tau khoov los xyuas kom muaj kev ua haujlwm zoo nyob rau hauv txoj kev nyuaj lossis kev txwv ib puag ncig.
4. Kev Ntsuam Xyuas Ib puag ncig
• Kub Cycling Test: Muab lub cable rau qhov kub thiab txias (siab thiab qis) thiab cycles ntawm lawv. Qhov no simulates yuav ua li cas lub cable yuav ua nyob rau hauv txawv climatic tej yam kev mob. Qhov kev sim kuaj xyuas qhov kev hloov pauv ntawm cov yam ntxwv kho qhov muag (xws li attenuation) tom qab kub hloov pauv.
• Kev Ntsuas Dej Dej: Ua kom lub cev muaj peev xwm tiv taus dej nkag, uas tuaj yeem ua rau lub teeb liab fiber ntau poob. Hauv qhov kev sim no, ib feem ntawm lub cable yog submerged nyob rau hauv dej, thiab lub peev xwm los thaiv cov dej nkag mus yog ntsuas.
• UV Resistance Test: Rau cov cables sab nraum zoov, raug UV hluav taws xob tuaj yeem degrade cov ntaub ntawv raws sijhawm. Qhov kev sim no kuaj xyuas lub plhaub lub peev xwm los tiv thaiv UV teeb thiab tswj kev ua haujlwm.
5. Kev Ntsuas Hluav Taws Xob thiab Kev Ntsuas Hluav Taws Xob
• Kev Ntsuas Hluav Taws Xob: Ntsuas seb lub cable ua li cas thaum raug hluav taws. Qee qhov chaw, zoo li cov chaw zov me nyuam, xav tau cov kab hluav taws xob kom ua tau raws li cov qauv kev nyab xeeb hluav taws kub ceev kom tiv thaiv kev sib kis ntawm cov nplaim taws.
• Kev Ntsuas Hluav Taws Xob thiab Kev Ua Phem Txhaum Cai: Ntsuas qhov muaj pes tsawg leeg thiab muaj kuab lom ntawm cov pa luam yeeb uas tsim thaum lub cable hlawv. Cov pa luam yeeb tsawg, xoom-halogen (LSZH) cables feem ntau xav tau nyob rau hauv qhov chaw kaw kom ntseeg tau tias muaj kev nyab xeeb thaum muaj hluav taws.
6. Kev xeem ntxiv
• Cable Sheath Integrity Test: Qhov no kuaj xyuas qhov tsis zoo ntawm cov ntaub thaiv npog uas tuaj yeem ua rau cov dej noo lossis cov kab mob nkag mus thiab ua rau cov fibers puas.
• Impact Test: Simulates sab nraud shocks, xws li kev huam yuaj los yog ntaus, kom ntseeg tau tias lub cable yuav nqus tau tej yam tsis muaj kev degradation.
Tau kawg, mastering ob peb qhov kev txawj ntse kom paub qhov txawv ntawm qhov zoo ntawm optical cables tsuas yog ib qho. Raws li tus neeg yuav khoom, nws yog qhov tseem ceeb dua kom nrhiav tau tus neeg muag khoom tsim nyog kho qhov muag. Tsis tsuas yog qhov kho qhov muag cable zoo txhim khu kev qha thiab tus nqi tsim nyog, tab sis kuj tsis muaj teeb meem nrog lub tuam txhab kev tsim nyog. Hengtong Optoelectronic Technology Co., Ltd. muaj ntau tshaj 30 xyoo ntawm kev paub nyob rau hauv optical fiber cable ntau lawm, nrog rau industrial bases thoob plaws lub ntiaj teb no. Yog tias koj xav yuav thiab sib piv, thov koj xav tiv tauj peb. Ntau yam khoom siv kho qhov muag xws li ADSS / OPGW muaj nyob rau hauv ib qho chaw nres tsheb!
