Cov kab mob fiber ntau dua yog qhov sib txuas lus ntawm niaj hnub no, muab cov ntaub ntawv hloov ceev nrawm nrog cov teeb liab tsis muaj tsawg. Tab sis txawm hais tias lawv lub durability thiab efficiency, lawv tsis yog indestructible. Ib yam li lwm cov thev naus laus zis, cov cable kho qhov muag tuaj yeem ua rau tsis taus lossis poob dhau lub sijhawm.
Hauv cov blog no, peb yuav tshawb nrhiav cov laj thawj uas yog vim li cas thiaj li kho qhov teeb meem, yuav ua li cas thiaj kuaj teeb meem, thiab kev coj ua zoo tshaj plaws kom ntev lawv lub neej.
Cov Ua Rau Ntawm Qhov Kho Tsis Zoo Optical
A. Lub cev puas tsuaj
Kev siv kho qhov muag yog ua los ntawm iav (lossis qee zaum yas), uas yog tsis yooj yim txawm tiv thaiv cov txheej txheem tiv thaiv. Cov ua rau lub cev puas muaj xws li:
Dabtsi yog khoov lossis cov khaub ncaws daj ntau dhau yuav ua rau cov kab nrib hauv cov micro-tawg, coj mus rau teeb liab poob (atrishing).
Crushing los yog pinching-hnyav cov khoom lossis cov kev txhawb nqa tsis muaj tseeb tuaj yeem tsoo cov fibers.
Cov nas lossis cov kab ua kom puas tsuaj rau hauv av lossis av blesial yuav tau zom los ntawm cov tsiaj.
B. Ib puag ncig cov ntsiab lus
Cov khoom noj noo-yog tias dej nkag mus rau txoj hlua cable, nws tuaj yeem ua kom tsis muaj zog thiab corrode sib txuas.
Qhov ntsuas kub muaj zog heev-huab cua sov lossis txias tuaj yeem nthuav cov ntaub ntawv sib cog lus \/ cog lus, ua rau muaj kev ntxhov siab pob txha lov.
UV raug-sab nraum zoov cables yam tsis muaj UV-resistant tsho yuav ua rau lub sijhawm.
C. Kev Raug Cai Kho Mob
Cov tsis zoo-ua tau zoo fiber ntau dua lossis pleev xim.
Cov ntsiab lus tsis muaj zog spricip lossis faulty connorsors.
Imploterly thov gel sau (hauv xoob-raj-raj-raj-raj cables).
D. Kev laus thiab hnav
Txawm tias cov khoom siv kho qhov muag tau txwv tsis pub dhau xyoo dhau los vim:
Cov khoom siv tsis nkees-tsis tu siab los ntawm cua, hloov qhov kub thiab txias, lossis kev co.
Cov tshuaj lim dej-hars chaw ib puag ncig (xws li, cov dej qab ntsev, cov chaw muaj corrode.
Yuav ua li cas los xyuas qhov tsis zoo kho qhov muag cable?
Yog tias koj lub fiber ntau lub network tau ntsib teeb meem, ntawm no yog yuav kuaj xyuas cov cable tsis ua hauj lwm:
A. Kev Ntsuam Xyuas Kev Pom Zoo
Saib rau "pom tawg, khoov, lossis tawg" hauv cov fiber.
Kuaj cov txhab rau "hmoov av, khawb, lossis misalignment".
B. Optical Lub Sij Hawm-Sau Reflectometer (OTDr) Xeem
OTDR xa cov ntawv pulses teeb pom kev zoo thiab kev ntsuas kom muaj chaw:
Cov ntsiab lus teeb liab (taw qhia tawg lossis tsis zoo).
Attenuate ntau qib (siab dua li xav tau=puas fiber).
C. Kev kuaj lub zog ntsuas
Kev ntsuas lub teeb xa lub zog muaj zog. Ib pliag tawm hauv lub hwj chim qhia cov fiber ntau puas.
D. Network Kev Ua Haujlwm Kev Ua Haujlwm
Qeeb maj nrawm lossis sib txuas sib txuas yuav qhia tau fiber ntau.
Tiav teeb liab poob feem ntau txhais tau tias yog tawg hauv cable.
Yuav ua li cas txuas lub neej ntawm cov khoom siv optical?
Thaum lub sij hawm kho qhov muag tuaj yeem kawg "{{25+}} xyoo", kev coj ua kom zoo thiab txij nkawm yog tus yuam sij:
Siv cov hluav taws xob zoo-nqis peev ntau hauv cov npe nrov nrog cov khoom tiv thaiv muaj zog.
Zam kev nruj-ua raws cov chaw tsim khoom lag luam yog qhov tsawg kawg nkaus khoov bend radius cov txheej txheem.
Tiv thaiv los ntawm harsh ib puag ncig- siv cov caj pas lossis dej tsis muaj dej sab nraum zoov.
Kev tshawb xyuas ib txwm-kuaj xyuas rau lub cev puas, tshwj xeeb tshaj yog nyob rau hauv cov chaw pheej hmoo siab.
Kom tsim nyog-zam kev rub tawm ntau dhau lossis tsoo thaum xa khoom.
Thaum twg koj yuav tsum hloov kho qhov muag cable?
Yog tias otdr kev xeem ntawv qhia cov teeb liab tseem ceeb poob ntawm ntau cov ntsiab lus.
Yog tias lub cable tau pom kev puas tsuaj (tawg, kinks, lossis cov ntu crushed).
Yog hais tias cov sib txuas yog corroded los yog tawg dhau ntawm kho.
Yog tias kev ua haujlwm network ua haujlwm ua rau muaj teeb meem txawm tias muaj teeb meem.

Yog-txawm tias lawv tau siv tau zoo heev, kho qhov muag kho kho qhov muag "vim kev tsis txaus siab rau lub cev, ib puag ncig cov yam, lossis kev laus. Cov xov xwm zoo? Nrog rau kev tsim kom tsim nyog, tuav, thiab txij nkawm, koj tuaj yeem ua kom lawv lub neej zoo heev thiab ua kom muaj kev txhim khu kev qha rau ntau caum xyoo.
