Fiber optic transceiver yog Ethernet kis tawm xov xwm hloov dua siab tshiab chav tsev uas sib pauv cov kab hluav taws xob luv luv twisted-pair hluav taws xob thiab cov teeb liab nyob deb.Nws tseem hu ua photoelectric converter (Fiber Converter) nyob rau ntau qhov chaw.
1. Lub teeb Link tsis teeb
(1) Tshawb xyuas seb cov kab hluav taws xob kho qhov muag puas qhib;
(2) Tshawb xyuas seb puas muaj cov kab hluav taws xob kho qhov muag poob loj dhau, uas tshaj qhov tau txais ntau ntawm cov khoom siv;
(3) Tshawb xyuas seb qhov kev sib txuas ntawm fiber ntau txuas puas raug, lub zos TX txuas nrog cov chaw taws teeb RX, thiab cov chaw taws teeb TX txuas nrog RX hauv zos.(d) Tshawb xyuas seb lub optical fiber connector puas raug muab tso rau hauv lub cuab yeej interface, seb hom jumper puas phim lub cuab yeej interface, seb hom ntaus ntawv puas phim cov khoom siv fiber ntau, thiab seb qhov sib kis ntev ntawm lub cuab yeej cuam tshuam li cas.
2. Lub Circuit Court Link teeb tsis teeb
(1) Xyuas seb lub network cable puas qhib;
(2) Tshawb xyuas seb hom kev sib txuas puas sib xws: daim npav network thiab routers thiab lwm yam khoom siv siv cov kab sib txuas, thiab cov keyboards, hubs thiab lwm yam khoom siv ncaj qha los ntawm cables;
(3) Txheeb xyuas seb qhov sib kis ntawm cov cuab yeej sib phim.
3. Cov ntaub ntawv network poob loj heev
(1) Qhov chaw nres nkoj hluav taws xob ntawm lub transceiver thiab lub network ntaus ntawv interface, los yog hom duplex ntawm cov cuab yeej interface ntawm ob qho kawg tsis sib xws;
(2) Muaj teeb meem nrog cov twisted khub cable thiab RJ-45 lub taub hau, yog li kos;
(3) Fiber kev twb kev txuas teeb meem, seb lub jumper yog raws li nyob rau hauv lub ntaus ntawv interface, seb lub pigtail phim lub jumper thiab lub coupler hom, thiab lwm yam .;
(4) Txawm hais tias cov kab hluav taws xob kho qhov muag poob siab tshaj qhov tau txais kev nkag siab ntawm cov khoom siv.
4. Tom qab fiber ntau optic transceiver txuas nrog, ob qhov kawg tsis tuaj yeem sib txuas lus
(1) Kev sib txuas ntawm fiber ntau yog thim rov qab, thiab cov fiber ntau txuas nrog TX thiab RX tau hloov pauv;
(2) RJ45 interface thiab cov cuab yeej sab nraud tsis txuas nrog kom raug (ua tib zoo saib rau qhov ncaj-dhau thiab splicing).Optical fiber interface (ceramic ferrule) tsis sib xws.Qhov kev ua txhaum no feem ntau tshwm sim hauv 100M transceiver nrog photoelectric kev sib koom ua haujlwm, xws li APC ferrule.Lub pigtail txuas nrog lub transceiver ntawm PC ferrule yuav tsis sib txuas lus ib txwm, tab sis nws yuav tsis cuam tshuam rau qhov tsis yog-optical kev sib nrig sib tswj transceiver.
5. Qhib thiab tawm qhov tshwm sim
(1).Tej zaum nws yuav yog qhov kev kho qhov muag attenuation loj heev.Lub sijhawm no, lub ntsuas hluav taws xob kho qhov muag tuaj yeem siv los ntsuas lub zog kho qhov muag ntawm qhov kawg tau txais.Yog tias nws nyob ze ntawm qhov tau txais ntau yam kev xav, nws tuaj yeem raug txiav txim raws li kev kho qhov muag tsis ua haujlwm nyob rau hauv thaj tsam ntawm 1-2dB;
(2).Tej zaum nws yuav yog qhov hloov pauv txuas nrog lub transceiver faulty.Lub sijhawm no, hloov qhov hloov pauv nrog lub PC, uas yog, ob lub transceivers txuas ncaj qha rau PC, thiab ob qho kawg yog PING.Yog tias nws tsis tshwm sim, nws tuaj yeem raug txiav txim raws li kev hloov pauv.txhaum;
(3).Lub transceiver yuav faulty.Lub sijhawm no, koj tuaj yeem txuas ob qhov kawg ntawm transceiver mus rau PC (tsis txhob mus dhau qhov hloov).Tom qab ob qho tag nrho tsis muaj teeb meem nrog PING, hloov cov ntaub ntawv loj dua (100M) lossis ntau dua los ntawm ib kawg mus rau lwm qhov, thiab saib nws qhov nrawm, yog tias qhov nrawm nrawm heev (cov ntaub ntawv hauv qab 200M tuaj yeem xa mus rau ntau tshaj 15 feeb), Nws tuaj yeem raug txiav txim raws li qhov tsis ua haujlwm transceiver
6. Tom qab lub tshuab tsoo thiab rov pib dua, nws rov qab mus rau qhov qub
Qhov tshwm sim no feem ntau 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, qee cov pob ntawv uas muaj qhov yuam kev hauv cov txheej txheem no tsis tuaj yeem kuaj pom hauv CRC qhov yuam kev thiab tshawb xyuas qhov ntev.Cov pob ntawv no yuav tsis raug xa tawm lossis muab pov tseg thaum lub sijhawm xa mus.Lawv yuav sau nyob rau hauv lub dynamic buffer.(Buffer), nws tsis tuaj yeem xa tawm.Thaum qhov tsis muaj puv, nws yuav ua rau lub qhov hloov pauv.Vim hais tias lub sij hawm no restarting lub transceiver los yog restarting lub hloov yuav rov qab tau cov kev sib txuas lus mus rau qhov qub.
