Cov qauv kev lag luam thiab ntsuas cov ntaub ntawv rau Fiber Optic Cable Lifespan
Raws li International Electrotechnical Commission (IEC 60793-}2-50) thiab Telecommunications Industry Association (TIA-568.3-D) cov qauv, cov qauv tsim qauv ntawm ib hom fiber ntau yog 25-30 xyoo, thiab cov fiber ntau fiber ntau yog 15-20 xyoo (cov ntaub ntawv qhov chaw: TIA fiber ntau lub neej) Txawm li cas los xij, hauv kev siv tiag tiag, lub neej yuav luv luv vim yog cov hauv qab no:
1. Kev puas tsuaj rau lub cev: Lub vojvoog dabtsi yog khoov tsawg dua 5 npaug ntawm txoj kab uas hla (piv txwv li, Ø2mm cable xav tau kom muaj lub vojvoog dabtsi yog khoov ntau dua 10mm) tuaj yeem txo qhov kev ua neej ntev dua 50% (Corning tuam txhab kev sim cov ntaub ntawv).
2. Environmental Corrosion: In high-temperature (>70℃) or high-humidity (>85% RH) ib puag ncig, lub neej ntev tuaj yeem poob mus rau 10-15 xyoo (daim ntawv qhia, "Fiber Optic Aging Test").
Plaub yam tseem ceeb cuam tshuam rau Fiber Optic Cable Lifespan
1. Cov Khoom Siv Zoo: Siab-cov fiber ntau zoo (xws li fluorine-doped iav) muaj zog tiv thaiv- cov khoom laus; Cov yas tsis zoo (POF) yuav tsum tau hloov txhua 3-5 xyoos.
2. Txoj Kev Txhim Kho Kev Txhim Kho Aerial Kev teeb tsa muaj qhov cuam tshuam rau UV degradation, thaum cov kev teeb tsa hauv av yuav tsum tau tiv thaiv cov nas puas.
3. Usage Frequency Frequent plugging and unplugging (>500 lub sij hawm) yuav ua rau connector hnav, yuav tsum tau hloov ntxov ntxov ntawm patch cords (Finisar kuaj pom zoo).
4. Kev cuam tshuam sab nraud: Cov hluav taws xob muaj zog (xws li nyob ze - qhov chaw nres tsheb hluav taws xob hluav taws xob) tuaj yeem ua kom cov tawv nqaij laus.
Thaum twg thiaj hloov tau? Peb Lub Teeb Pom Kev Pom Zoo:
1. Performance Degradation: Optical attenuation >0.5dB/km (single-mode) or >3.5dB / km (ntau hom) (ISO / IEC 14763-3 tus qauv).
2. Lub cev Deformation: Sheath cracking, raug fiber ntau core, los yog connector oxidation (pom ntsuab tooj liab xeb).
3. Network Failure: Kev tsis sib txuas tsis tu ncua (tuaj yeem kuaj tau siv OTDR ntaus ntawv).
Cov Lus Qhia Txog Kev Kho Mob:
- Tshawb xyuas txuas ntxiv txhua 2 xyoos siv lub teeb liab cwj mem; huv si connectors nyob rau hauv cov ntaub ntawv chaw peb lub hlis twg (tsis txhob haus cawv corrosion ntawm txheej).
- Ua ntej LSZH (Low Smoke Halogen-Free) sheath material; cov kab hluav taws xob sab nraum zoov xav tau kev tiv thaiv armor.
