Qhov 50 / 125μm thiab 62.5 / 125μm multimode fiber ntau hom fiber ntau hauv cov khoom sib txuas ua ke, uas 50μm thiab 62.5μm sawv cev rau lub taub ntawm cov tub ntxhais siv los ua cov cim hluav taws xob hauv optical fiber, thaum 125μm sawv cev rau txoj kab uas hla ntawm cladding , uas tuaj yeem tiv thaiv tus tub ntxhais thiab txwv qhov kev tshaj tawm ntawm lub teeb nyob rau hauv tub ntxhais. Txawm hais tias qhov cladding loj ntawm ob lub multimode fibers no zoo ib yam, cov tub ntxhais sib txawv ua lawv cov bandwidth sib txawv. Yog li, puas tau ob hom multimode fiber no sib xyaw tau? Dab tsi yog qhov cuam tshuam ntawm kev sib xyaw ntawm kev sib kis tau ntawm cov khoom siv fiber ntau?
Raws li ISO 11801 tus qauv, cov roj ntsha multimode tuaj yeem faib ua OM1, OM2, OM3, OM4 thiab OM5. Cov tub ntxhais txoj kab uas hla ntawm om1 multimode fiber ntau yog 62.5μm, thiab cov tub ntxhais txoj kab uas hla ntawm plaub seem plaub multimode tsuas yog 50μm. Tsib tsib hom ntawm cov xov tooj hluav taws xob sib txawv muaj qhov sib txawv ntawm cov khoom sib kis, sib kis deb thiab cov xim sheath. Qhov me dua qhov taub loj dua, ntau dua qhov sib kis thiab qhov ntev kis kis.
Vim li cas muab cov roj carbon fiber ntau?
Lub 62.5μm multimode fiber ntau siv nyob rau hauv 10 / 100Mbps Ethernet nrog lub teeb ci ntsa iab emode (LED) ua lub teeb ci. Nrog cov kev txhim kho txuas ntxiv mus ntawm cov network nrawm, ntau hom kho qhov muag fiber ntau nrog LED raws li lub teeb pom kev tau deb ntawm kev ua tiav cov kev xav tau ntawm cov kev sib txuas hauv high-speed network. Yog li no, 50μm multimode fiber ntau nrog kab noj hniav ntsug emitting laser (VCSEL) raws li lub teeb ci tau tawm. Piv nrog LED pom, 50μm multimode fiber ntau nrog VCSEL raws li lub teeb pom kev muaj hwj chim siab dua thiab zoo dua tso zis laser. Yog li no, 50μm multimode fiber yog siv ntau thiab dav dua. Txawm hais tias muaj ntau cov tes hauj lwm loj (xws li cov chaw zov me nyuam cov ntaub ntawv) tau teeb nrog 50μm multimode fiber, tseem muaj ntau daim ntawv thov uas yuav tsum siv 62,5μm multimode fiber. Yog li no, qhov thov xav tau ntau dua 50μm thiab 62.5μm multimode fiber kuj tseem nce zuj zus.
Dab tsi yog cov teeb meem nrog hybrid multimode fiber ntau?
Muaj ob kis ntawm hybrid multimode fiber. Ib qho yog lub teeb nkag ntawm 62.5 / 125μm multimode fiber ntau rau 50 / 125μm multimode fiber. 50 / 125μm multimode fiber muaj lub zog me me txoj kab uas hla thiab tuaj yeem yooj yim txuas nrog 62.5 / 125μm multimode fiber. Hauv qhov no, qhov txhaum cai ntawm kev sib dhos thiab kev sib koom ntawm lub kaum ntse ntse yuav tsis muaj kev cuam tshuam zoo rau kev xa cov fiber.
Lwm qhov yog tias lub teeb nkag ntawm 50 / 125μm multimode fiber ntau rau 62.5 / 125μm multimode fiber. Thaum 62.5 / 125μm multimode fiber ntau sib xyaw nrog 50 / 125μm multimode fiber, vim qhov loj dua qhov taub loj ntawm yav dhau los, lub teeb nyob rau hauv 62.5 / 125μm multimode fiber yuav tawg ntawm cov tub ntxhais mus rau cladding ntawm 50 / 125μm multimode fiber, uas ua rau nyob rau hauv ib feem ntawm poob. Yog tias cov fiber ntau poob loj, nws tsis pom zoo kom sib xyaw ua ke 62.5 / 125μm thiab 50 / 125μm multimode fiber.
Txawm hais tias lub teeb laser los ntawm 50μm thiab 62.5 μm multimode fiber ntau qhov sib txawv, lawv muaj qhov sib txuam tau zoo, tab sis nws raug nquahu kom koj tsis txhob sib xyaw ntawm cov plaub hau sib txawv hauv ib qho txuas. Yog tias qhov poob yog nyob hauv koj qhov ntau, koj tuaj yeem sib tov 50 μm thiab 62.5 μm multimode fibers raws li qhov tsim nyog.
Tsis yog tsuas yog kev sib xyaw ntawm 62.5 μm thiab 50 μm multimode fiber yog qhov tseem ceeb, tab sis kuj tseem muaj qhov sib txuam ntawm cov xov hluav taws xob ntau nrog cov bandwidth sib txawv lossis los ntawm cov neeg muab khoom sib txawv xav tau them rau.
