Yuav daws qhov Failure ntawm Fiber Optic Transceiver li cas?

Raws li peb txhua tus paub, fiber ntau optic transceiver yog ib qho Ethernet kis tau tus mob ntaus ntawv uas sib hloov sib tw-pair hluav taws xob signals thiab optical fiber optical signals, yog li nws tseem hu ua photoelectric converter. Kev siv fiber ntau optic transceivers tuaj yeem txuas ntxiv kev sib kis ntawm lub network mus rau ntau tshaj 100 mais. Kuv ntseeg tias qee zaum koj yuav ntsib qee qhov teeb meem thaum siv fiber ntau optic transceivers. Tsis ntev los no, qee cov neeg siv tau sab laj txog qhov teeb meem ntawm fiber ntau optic transceivers crashing. Cov hauv qab no yog qhia rau koj yuav ua li cas los daws qhov kev poob qis ntawm fiber ntau optic transceiver.
1. Feem ntau, ntau qhov xwm txheej ntawm kev sib txuas hauv network yog tshwm sim los ntawm kev hloov. Qhov kev hloov yuav ua CRC qhov yuam kev tshawb pom thiab tshawb xyuas qhov ntev ntawm txhua cov ntaub ntawv tau txais. Yog tias kuaj pom qhov yuam kev, pob ntawv yuav raug muab pov tseg, thiab cov pob ntawv raug yuav raug xa mus. Txawm li cas los xij, nyob rau hauv cov txheej txheem no, qee cov pob ntawv yuam kev tsis tuaj yeem kuaj pom hauv CRC qhov yuam kev thiab tshawb xyuas qhov ntev. Cov pob ntawv zoo li no yuav tsis raug xa tawm thaum lub sijhawm xa mus, thiab lawv yuav tsis muab pov tseg. Lawv yuav tau sau nyob rau hauv lub dynamic buffer (tsis), nws yuav tsis raug xa tawm, thiab thaum lub buffer puv, nws yuav ua rau lub hloov mus poob. Vim tias lub sijhawm no, rov pib dua lub transceiver lossis rov pib dua qhov hloov pauv tuaj yeem rov ua qhov kev sib txuas lus mus rau qhov qub, yog li cov neeg siv feem ntau xav tias nws yog qhov teeb meem nrog lub transceiver.
2. Tsis tas li ntawd, lub nti sab hauv ntawm lub optical fiber transceiver kuj tseem yuav poob rau hauv cov xwm txheej tshwj xeeb, uas feem ntau cuam tshuam nrog kev tsim. Yog tias nws poob, rov ua lub zog ntawm lub cuab yeej.
3. Thaum tshav kub kub dissipation teeb meem ntawm optical fiber transceiver. Feem ntau, fiber ntau optic transceivers tau siv rau lub sijhawm ntev; lawv laus lawm. Cov cua sov ntawm tag nrho cov cuab yeej yuav ua kom loj thiab loj dua. Yog tias qhov kub thiab txias heev, nws yuav poob. daws; hloov lub fiber optic transceiver. Los yog siv ib puag ncig los ntxiv qee qhov kev ntsuas kub dissipation. Qhov ntsuas kub dissipation zoo ib yam li lub computer heat dissipation, yog li kuv yuav tsis piav qhia lawv ib qho ntawm no.
4. Lub hwj chim mov ntawm lub optical fiber transceiver. Qee cov khoom siv hluav taws xob tsis zoo yuav tsis ruaj khov tom qab siv tau ntev. Txhawm rau txiav txim siab qhov no, koj tuaj yeem kov lub hwj huam mov nrog koj txhais tes kom pom tias nws kub heev. Yog tias cov khoom siv hluav taws xob yuav tsum tau hloov tam sim ntawd, cov khoom siv hluav taws xob tsis tshua muaj nqi thiab tsis muaj nqi tu.
