Txuj Ci
OS1 ib hom fiber ntau optic thaj kab ua raws li ITU-T G.652 tus qauv, suav nrog ITU-T G.652.A thiab ITU-T G.652B cov qauv (cov lus pom zoo), ITU-T G.652C thiab G.652D cov qauv (dej siab kawg). Tab sis OS2 ib hom fiber ntau yog hais txog cov fiber ntau uas ua raws li cov qauv fiber ntau G.652C lossis G.652D, kuj tseem hu ua ib-hom xoom-dej-ncov fiber ntau lossis ib hom hom qis-dej-ncov fiber ntau. Cov kua dej qis-ncov hluav taws xob no feem ntau siv hauv CWDM (Coarse Wave Division Use) daim ntawv thov. Tsis tas li ntawd, tus tshiab cabling txheem G.657.A1 tau muab rau kev khoov-insensitive ib hom fiber ntau optic thaj cords kom ua rau txoj kev ua tau zoo dua tus nqi ntawm cov khoom siv fiber ntau.
Kev teeb tsa cable
OS1 ib hom fiber ntau feem ntau adopts nruj raj qauv thiab yog tsim rau cov kev siv sab hauv tsev. Nws feem ntau muaj kev tiv thaiv zoo nyob rau sab nraud, thiab cov khoom khi ntawm cov hluavtaws fiber ntau (xws li cov xov xov aramid) yog qhwv hauv nruab nrab. Lub hauv paus tseem ceeb thiab txheej txheem ntawm OS1 ib hom fiber ntau tau los ntawm iav, uas tsis tuaj yeem khoov thiab tsis yooj yim. Cov txheej tsho muaj lub luag haujlwm tiv thaiv thiab tuaj yeem txuas lub neej ntawm fiber ntau. OS2 ib hom fiber ntau feem ntau adopts xoob raj tsim, uas yog ntau haum rau sab nraum zoov daim ntaub ntawv. Thaum xa tawm mus rau hauv qee qhov chaw huab ib puag ncig, yuav tsum muaj txoj hlua cable muaj zog ntxiv. Tus OS2 ib hom fiber ntau yog helically tso rau hauv ib txoj raj uas nruj, yog li OS2 tuaj yeem rub tawm kom tsis muaj dabtsi yog khoov rau sab hauv los tiv thaiv lub fiber ntau los ntawm kev puas tsuaj loj.
Tus nqi tsawg
Attenuation tus nqi ntawm OS1 ib hom fiber ntau yog qhov ntau dua li ntawm OS2 ib leeg-modefiber. Feem ntau, qhov siab tshaj plaws attenuation tus nqi ntawm OS1 ib hom fiber ntau hauv 1310nm thiab 1550nm bands yog 1.0db / km, thaum lub siab tshaj plaws attenuation tus nqi ntawm OS2 yog 0.4db / km. Ib qho ntxiv, lawv txoj kev sib kis tseem sib txawv. Qhov siab tshaj qhov kis tau tus mob ntawm OS1 ib hom fiber ntau yog 10km, thaum qhov kev sib kis ntau tshaj ntawm OS2 ib hom fiber ntau tuaj yeem ncav 200km. Ob qho tib si OS1 thiab OS2 ib hom fiber ntau tuaj yeem ua tiav cov kis ntawm 1 mus rau 10GbE ntawm cov kis sib txawv. Ntxiv rau, OS2 hom ib hom fiber ntau kuj tseem siv tau 40G / 100G Ethernet kis.
