Optical modules thiab optical fiber transceivers yog cov khoom siv uas ua rau kev hloov pauv photoelectric.Qhov txawv ntawm lawv yog dab tsi?Niaj hnub no, cov ntaub ntawv nyob deb kis tau tus mob siv nyob rau hauv ntau yam ntse tej yaam num yeej siv optical fiber kis tau tus mob.Kev sib txuas ntawm qhov no yuav tsum tau kho qhov muag modules thiab fiber ntau optic transceivers.Yog li, ob qho no yuav tsum sib txuas li cas, thiab dab tsi yuav tsum tau them rau?
1. Optical module
Kev ua haujlwm ntawm optical module kuj yog kev hloov pauv ntawm cov teeb liab photoelectric.Nws yog tsuas yog siv rau cov cab kuj ntawm qhov hloov thiab lub cuab yeej.Nws muaj tib lub hauv paus ntsiab lus xws li optical fiber transceiver, tab sis qhov kho qhov muag module yog qhov ua tau zoo thiab muaj kev nyab xeeb dua li qhov transceiver.Optical modules raug cais raws li daim ntawv pob.Feem ntau suav nrog SFP, SFP +, XFP, SFP28, QSFP +, QSFP28, thiab lwm yam.
2. Optical fiber ntau transceiver
Optical fiber transceiver yog ib qho khoom siv uas hloov cov teeb liab hluav taws xob luv luv thiab cov teeb liab nyob deb.Nws feem ntau yog siv nyob rau hauv kev sib kis mus ntev, kis tau los ntawm optical fibers, converting hluav taws xob teeb liab mus rau optical signals thiab xa lawv.Lub teeb liab tau txais yog hloov dua siab tshiab rau hauv hluav taws xob teeb liab.Nws tseem hu ua Fiber Converter nyob rau ntau qhov chaw.
Fiber optic transceivers muab cov kev daws teeb meem pheej yig rau cov neeg siv uas yuav tsum tau hloov kho qhov system ntawm tooj liab xaim mus rau fiber ntau optics, tab sis tsis muaj peev txheej, cov neeg ua haujlwm lossis lub sijhawm.
3. Qhov txawv ntawm optical module thiab optical fiber transceiver
① Active thiab passive: Lub optical module yog ib qho kev ua haujlwm module, lossis ib qho khoom siv, yog ib qho khoom siv tsis tuaj yeem siv ib leeg, thiab tsuas yog siv hauv cov keyboards thiab cov khoom siv nrog optical module slots;optical fiber transceivers yog cov khoom siv ua haujlwm.Nws yog ib qho khoom siv sib cais, uas tuaj yeem siv ib leeg thaum ntsaws;
② Txhim kho kev teeb tsa: Lub kho qhov muag module txhawb kev sib pauv kub, kev teeb tsa kuj hloov tau;qhov kho qhov muag fiber ntau transceiver yog qhov ruaj, thiab kev hloov thiab hloov kho yuav muaj teeb meem ntau dua;
③Price: Optical fiber transceivers yog pheej yig dua optical modules thiab kuj yog kev lag luam thiab siv tau, tab sis kuj yuav tsum tau xav txog ntau yam xws li fais fab adapter, teeb pom kev zoo, network cable raws li txoj cai, thiab lwm yam.
④ Daim ntawv thov: Optical modules yog siv rau hauv cov khoom siv kho qhov muag sib txuas lus, xws li kev sib txuas lus kho qhov muag ntawm kev sib txuas sib txuas, cov tub ntxhais routers, DSLAM, OLT thiab lwm yam khoom siv, xws li: khoos phis tawj video, cov ntaub ntawv sib txuas lus, kev sib txuas lus wireless thiab lwm yam khoom siv fiber ntau optical;optical fiber transceiver Nws yog siv nyob rau hauv lub network tiag tiag ib puag ncig qhov twg Ethernet cable tsis tuaj yeem npog thiab yuav tsum siv cov fiber ntau optical kom ntev qhov kev sib kis, thiab feem ntau yog teem raws li cov txheej txheem nkag mus rau hauv broadband cheeb tsam network;
4. Dab tsi yuav tsum tau them sai sai rau thaum txuas lub optical module thiab optical fiber transceiver?
① Qhov ceev ntawm optical module thiab optical fiber transceiver yuav tsum zoo ib yam, 100 megabytes rau 100 megabytes, gigabit rau gigabit, thiab 10 megabytes rau 10 trillion.
② Lub wavelength thiab kis tau tus mob yuav tsum zoo ib yam, piv txwv li, lub wavelength yog 1310nm los yog 850nm nyob rau tib lub sij hawm, thiab kis tau tus mob nrug yog 10km;
③ Hom lub teeb yuav tsum yog tib yam, ib leeg fiber ntau rau ib fiber ntau, dual fiber ntau rau dual fiber ntau.
④ Fiber jumpers lossis pigtails yuav tsum tau txuas nrog tib lub interface.Feem ntau, fiber ntau optic transceivers siv SC ports thiab optical modules siv LC ports.
