Hauv kev sib txuas lus kho qhov muag, kev nkag siab txhua hom fiber ntau optic cable yog qhov tseem ceeb thaum xaiv qhov tsim nyogfiber ntau optic cable. OS1 vs OS2 fibersawv cev rau ob qho ntawm feem ntauib hom fiber ntau hom. Thaum ob tug noSMF fiber ntau opticcables qhia ntau qhov sib xws, lawv pom qhov sib txawv tseem ceeb hauv daim ntawv thov scenarios, cov yam ntxwv ntawm kev ua tau zoo, thiab kev xav txog tus nqi. Yog li ntawd, qhov txawv ntawmOS1 thiab OS2 ib hom fiber ntauyog qhov tseem ceeb.
OS1 thiab OS2 Fiber yog dab tsi?
Ob leegOS 1 fiberthiabOS 2 fiberbelongs rau ib hom Fiber (SMF) qeb.Ib hom fiber ntautso cai rau tsuas yog ib hom ntawm lub teeb teeb liab kom nthuav tawm ncaj qha, kom ntseeg tau qhov sib kis tau ntev dua thiab ntau dua bandwidth. Qhov sib txawv tseem ceeb ntawm ob qho noib hom fiber ntauhom nyob rau hauv lawv lub hom phiaj tsim thiab kev siv ib puag ncig:
OS1 fiber optic cablefeem ntau yog siv rau sab hauv tsev luv luv- cov ntawv thov sib nrug deb, xws li cov chaw zov me nyuam, chaw ua haujlwm LANs, thiab kev sib txuas lus hloov chaw nyob hauv qhov chaw tswj hwm.
OS2 fiber optic cableyog tsim tshwj xeeb rau kev siv ntev -nyob sab nraum zoov, suav nrog kev sib txuas lus hauv nroog,fiber ntau opticnkag mus rau tes hauj lwm, thiab loj infrastructure tej yaam num.
Technical Standards thiab Compatibility Sib piv
OS1 Standard Specifications
OS1 ib hom fiber ntauua raws li ITU-T G.652 cov qauv (xws li ITU-T G.652A thiab ITU-T G.652B cov qauv rau cov khoom siv fiber ntau, nrog rau ITU-T G.652C thiab G.652D qauv rau cov dej tsis tshua muaj fiber ntau). Cov txheej txheem no txhais cov yam ntxwv ntawm cov paib hom fiber ntau, kom ntseeg tau tias kev ua tau zoo hauv tsev qis -bandwidth ib puag ncig.OS1 fiber cableFeem ntau tsom rau tus nqi -kev ua tau zoo thiab yooj yim rau kev teeb tsa sab hauv tsev.
OS2 Standard Specifications
OS2 SM fiberua raws li ITU-T G.652C lossis ITU-T G.652D cov qauv tshwj xeeb rau cov dej tsis tshua muaj fiber ntau, thiab tam sim no ib feem ua tau raws li cov qauv G.657.A1. Tus qauv G.657.A1 qhia txog cov dej tsis tshua muaj siab tshaj fiber ntau, txo qis attenuation nyob ze ntawm 1383nm wavelength, ua kom cov fiber ntau ua haujlwm thoob plaws qhov dav dav. Qhov no muabOS 2 fibermuaj zog khoov tsis kam thiab ib puag ncig adaptability, ua rau nws haum rau kev xa mus nyob rau hauv complex sab nraum zoov ib puag ncig.
Kev tsim qauv tsim thiab kev tsim qauv sib txawv
OS1 Fiber:Txais yuav nruj - buffered cable core tsim qhov twg txheej tiv thaiv qhwv nruj nreem nyob ib ncig ntawm cov tub ntxhais fiber ntau, muab kev tiv thaiv zoo thiab ua rau cov fiber ntau hloov tau thiab muaj zog. Txawm li cas los xij, thaum ntsib qhov kub hloov pauv, cov av noo siab, lossis sab nraum UV raug, nws qhov kev ua tau zoo thiab kev ua neej yuav raug cuam tshuam. Nws yog feem ntau siv rau cabling thiab txiav tawm hauv tsev, haum rau cov chaw sab hauv tsev uas yuav tsum tau khoov tsis tu ncua, txawm hais tias fiber ntau microbending tuaj yeem ua rau lub teeb liab poob.
OS 2 Fiber:Txais yuav ib qho xoob-tube tsim qhov twg cov fiber ntau yog nyob rau hauv ib lub gel-cov raj uas muaj qhov chaw nruab nrab ntawm nws thiab lub plhaub sab nraud. Qhov noOS2 SMF cabletuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias ntawm -40℃mus rau +70 degree, tuav kev nthuav dav thiab kev cog lus los ntawm kev hloov pauv kub. Cov gel filling muab cov dej noo zoo heev thiab dej tsis kam, thaum lub tsho sab nrauv feem ntau siv UV- cov ntaub ntawv tiv taus muaj peev xwm tiv taus lub hnub ntev ntev thiab txawm tias qee lub cev puas tsuaj. Nws yog tsim rau sab nraum zoov daim ntawv thov scenarios xws li underground burial, aerial, thiab ncaj qha faus installation.
Attenuation Performance thiab Tib Hom Fiber Distance
OS1 Attenuation yam ntxwv
OS 1 fibermuaj attenuation qhov tseem ceeb ntawm kwv yees li 1.0 dB / km ntawm 1310nm thiab 1550nm wavelengths. Nws txhawb nqa qhov siab tshaj plaws kis tau tus mob ntawm 10 kilometers, ua tau raws li qhov xav tau ntawm kev sib txuas ntawm cov ntaub ntawv hauv chaw nruab nrab lossis luv luv - kev sib txuas ntawm cov tsev.
OS2 Attenuation yam ntxwv
Qhov zoo tshaj plaws ntawmOS 2 fiberyog nws qis attenuation. Ntawm 1310nm wavelength, tus nqi attenuation tsuas yog 0.4 dB / km, thiab txawm qis dua ntawm 1550nm wavelength ntawm 0.25 dB / km. Qhov noOS2 ib hom fiber ntautxhawb kev sib kis deb ntawm 200 mais lossis ntxiv mus, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev sib txuas lus ntev - kev sib txuas lus thiab hla - hauv cheeb tsam network. Qhov txuas ntxivib hom fiber ntau nrugmuaj peev xwm kuj ua rau nws haum rau 40G / 100G Ethernet kev sib txuas.

Kev ua tau zoo thiab tus yam ntxwv ntawm tus nqi
OS 1 fibertau txais txiaj ntsig los ntawm nws nruj- cov qauv buffered nyob rau hauv ib puag ncig sab hauv, ua rau nws yooj yim rau kev txiav thiab tswj nrog ib qho yooj yim thiab ceev installation txheej txheem. Rau cov ntawv thov uas tsis xav tau ultra- kis tau tus mob ntev,OS 1muab bandwidth txaus thiab kev ntseeg siab thaum tswj tus nqi zoo -kev ua tau zoo. Nws cov txheej txheem tsim khoom yog qhov yooj yim nrog cov khoom siv qis dua, muab cov peev txheej qis dua tsim nyog rau cov lag luam me thiab nruab nrab - cov lag luam loj thiab pob nyiaj siv - cov phiaj xwm txwv.
Tsawg attenuation yam ntxwv ntawmOS2 ib hom fiber ntauua rau nws xaiv qhov kev xaiv ntev - kis tau tus mob. Kev poob qis dua txhais tau hais tias txo tus naj npawb ntawm repeaters thiab amplifiers, txo tag nrho cov kev sib txuas hauv network thiab cov nqi kho.OS 2txhawb nqa Dense Wavelength Division Multiplexing (DWDM) thiab Coarse Wavelength Division Multiplexing (CWDM) technologies, ua kom muaj kev sib kis ntawm ntau lub wavelength signals ntawm ib qho fiber ntau, txhim kho kev siv bandwidth zoo heev. Thaum pib cov nqi yuav khoom ntau dua, los ntawm qhov ntev - qhov kev xav, qhov rov qab los ntawm kev nqis peev zoo dua. Nws txo qhov kev xav tau ntawm cov khoom siv relay, txo cov nqi ua haujlwm. Kev pab lub neej ntev dua thiab muaj zog ib puag ncig adaptability txhais tau tias txo qis txij nkawm thiab hloov cov nqi. Rau cov phiaj xwm loj hauv network thiab ntev - qhov yuav tsum tau muaj kev sib kis, tus nqi tag nrho ntawm kev ua tswv cuab rauOS 2 cableyog qhov qis dua.
Kev Txhim Kho Yav Tom Ntej
