Txhim Kho FTH cov tes hauj lwm nrog cov fiber ntau kho qhov muag pib

Lub neej tom ntej ntawm kev sib txuas: tshawb xyuas fiber ntau qhov muag pib kho qhov muag cables rau ftth

Taw qhia hauv cov toj roob hauv pes puas tau-evolving, fiber ntau rau lub tsev (FTH) thev naus laus zis tau hloov kho peb nkag mus rau Is Taws Nem. Ntawm cov pivotal Cheebtsam ntawm ftth kev teeb tsa, cov fiber ntau kho qhov muag cable sawv tawm vim nws cov qauv tshwj xeeb thiab kev ua haujlwm. Niaj hnub no, peb delve rau hauv cov nta thiab kev qhia txuj ci ntawm cov cable no tseem ceeb, uas yog ua kom nrov rau cov chaw sib txuas.

Cov yam ntxwv ntawm fiber ntau kho qhov muag tau muab cov fiber ntau kho qhov muag ua kom tau zoo ua kom tau raws li cov ntawv thov ftth. Lawv muaj cim los ntawm:

• Central Fiber Cores : Muaj nyob rau hauv ib leeg-tub ntxhais, thiab plaub-core variants, cov cables muaj hloov hauv cov lej sib txuas.
• Cov tswv cuab lub zog : Muab tso rau ob sab ntawm cov tub ntxhais, cov ntaub ntawv xws li KFP (Kevlar Fiber Reinfored yas) lossis steel hlau muab kev txhawb nqa tshwj xeeb thiab lub zog tensile.
• Jacketing xaiv : tsawg pa taws lub halogen (LSZH) lossis PVC cov tsho loj ua cov ntaub pua chaw muaj kev nyab xeeb thiab haum rau cov pa tsis muaj tshuaj lom.
• Kev Tsim Kho Kev Tsim : Lub Cable Cov Slim Profile pab rau kev teeb tsa yooj yim los ntawm cov xaim hluav taws xob lossis ntawm cov chaw qhib tshiab thiab hloov kho tshiab hauv cov qauv tam sim no.

Kev qhia tshwj xeeb cov kev ua yeeb yam ntawm fiber ntau optical poob cables yog pom tseeb hauv lawv cov kev muaj zog:

• Sab nraud qhov ntev : cov sib txawv nyob ntawm tus naj npawb ntawm cov cores, nrog qhov loj me ua kom ntseeg tau tias qhov chaw tsawg kawg thaum ua tau zoo.
• Kub Kuj : Cov cable ua haujlwm tau zoo nyob rau hauv kub ntau ntawm -40 rau +60 degrees Celsius, kom ntseeg tau txoj kev ntseeg tau ib puag ncig ntau haiv neeg.
• Cov tshuab hluav taws xob ruaj khov : ntsuas rau lub zog siab thiab ua kom muaj zog, cov cable tuaj yeem tiv thaiv kev ntxhov siab ntawm lub cev tseem ceeb thiab nyob hauv av.

Cov ntawv thov thiab qhov zoo Fiber ntau qhov muag poob Cables yog tuaj yeem ua haujlwm hauv ntau cov xwm txheej suav nrog:

• Kev txhim kho hauv tsev : Yooj yim rau txoj hauv kev los ntawm cov chaw noj xov tooj hauv zos mus rau tus kheej.
• Network Enhancements : txhim kho cov kev ua lag luam network uas twb muaj lawm los txhawb nqa cov khoom lag luam bandwidth ntau dua.

• Lub neej thiab kev nyab xeeb : lawv txoj kev tsim kho kom muaj kev ua kom ntev thiab kev nyab xeeb, uas yog qhov tseem ceeb hauv cov chaw nyob.

Kev xaus fiber ntau cov cabion sawv cev rau ib qho kev nce qib tseem ceeb hauv kev kho qhov muag ntawm kev sib tw ntawm FTH. Lawv txoj kev tsim kho kom zoo, txuas nrog rau cov ntawv thov ntau yam, ua rau lawv xaiv qhov zoo tshaj plaws rau kev ua kom muaj txiaj ntsig, txhim khu kev qha ntau, thiab kev siv internet sib txuas hauv tsev. Raws li qhov kev thov kom nrawm dua thiab ntau dua kev sib txuas hauv Is Taws Nem
