Optical fiber ntau transceiver yog Ethernet kis tau tus mob media conversion unit uas interchanges luv-kis twisted-pair hluav taws xob signals thiab ntev-ntev optical signals.Nws tseem hu ua fiber ntau converter nyob rau hauv ntau qhov chaw.
Optical fiber ntau transceivers feem ntau yog siv nyob rau hauv lub network tiag tiag ib puag ncig uas tsis tuaj yeem them los ntawm Ethernet cables thiab yuav tsum siv cov fibers kho qhov muag kom ncua qhov kev sib kis, thiab feem ntau yog nyob rau hauv cov txheej txheem kev siv ntawm broadband metropolitan cheeb tsam network;xws li: high-txhais video duab xa mus rau kev saib xyuas thiab kev ruaj ntseg engineering;Nws kuj tseem ua lub luag haujlwm loj hauv kev pab txuas lub mais kawg ntawm fiber ntau mus rau metro thiab dhau mus.
Optical fiber transceivers yuav ntsib ntau yam teeb meem thaum siv.Hnub no, kuv yuav qhia rau koj txog cov kev ua txhaum thiab kev daws teeb meem ntawm optical fiber transceivers.
1. Lub teeb txuas yog raug kaw
(1) Tshawb xyuas seb cov kab hluav taws xob kho qhov muag puas puas lawm;
(2) Tshawb xyuas seb qhov poob ntawm cov kab hluav taws xob kho qhov muag puas loj dhau thiab tshaj qhov tau txais 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
(4) Tshawb xyuas seb lub tshuab hluav taws xob kho qhov muag puas zoo tso rau hauv cov cuab yeej sib txuas, seb hom jumper puas phim cov cuab yeej cuam tshuam, seb hom ntaus ntawv puas phim cov khoom siv fiber ntau, thiab seb lub cuab yeej sib kis ntev npaum li cas.
2. Lub Circuit Court Link teeb yog kaw
(1), xyuas seb lub network cable puas qhib Circuit Court;
(2) Txheeb xyuas seb hom kev sib txuas puas sib xws: daim npav network thiab routers thiab lwm yam khoom siv siv cov kab sib tw, 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 tsis phim lub interface ntawm lub network ntaus ntawv, los yog hom duplex ntawm cov cuab yeej interface ntawm ob qho kawg;
(2) Yog tias muaj teeb meem nrog tus khub twisted thiab lub taub hau RJ-45, xyuas nws;
(3) Optical 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 tias qhov poob ntawm cov kab hluav taws xob kho qhov muag tshaj qhov kev lees paub ntawm cov khoom siv.
4. Tom qab lub optical fiber transceiver txuas nrog, ob qhov kawg tsis tuaj yeem sib txuas lus
(1) Cov fibers kho qhov muag tau thim rov qab, thiab cov khoom siv kho qhov muag txuas nrog TX thiab RX yog thim rov qab;
(2) Kev sib txuas ntawm RJ45 interface thiab cov cuab yeej sab nraud yog qhov tsis raug (ua tib zoo saib rau qhov ncaj-dhau thiab splicing) thiab cov fiber ntau optical interface (ceramic ferrule) tsis sib xws.Qhov kev ua txhaum no feem ntau tshwm sim hauv 100M transceiver nrog optoelectronic kev sib koom ua haujlwm, xws li APC ferrule.Yog hais tias lub pigtail txuas nrog lub transceiver ntawm PC ferrule, nws yuav tsis muaj peev xwm sib txuas lus ib txwm, tab sis nws yuav tsis cuam tshuam rau kev sib txuas ntawm cov khoom siv hluav taws xob uas tsis yog-kho qhov muag-hluav taws xob kev sib txuas lus transceiver.
5. On and off phenomenon
(1) Nws yuav yog tias txoj kev kho qhov muag attenuation loj dhau.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) Nws tuaj yeem yog qhov hloov pauv txuas nrog lub transceiver yog qhov tsis raug.Lub sijhawm no, hloov qhov hloov pauv nrog PC, uas yog, ob lub transceivers tau txuas ncaj qha rau PC, thiab ob qhov kawg yog pinged.txhaum;
(3) Lub transceiver yuav faulty.Lub sijhawm no, koj tuaj yeem txuas ob qhov kawg ntawm transceiver mus rau PC (tsis yog los ntawm kev hloov).Tom qab ob qhov kawg tsis muaj teeb meem nrog PING, hloov cov ntaub ntawv loj (100M) ntawm ib kawg mus rau lwm qhov.Saib nws qhov ceev, xws li qeeb heev (hloov cov ntaub ntawv hauv qab 200M rau ntau tshaj 15 feeb), tuaj yeem txiav txim siab raws li qhov tsis ua haujlwm transceiver
6. Tom qab sib tsoo thiab rov pib dua, nws yuav 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 ntev ntawm tag nrho cov ntaub ntawv tau txais.Cov pob ntawv uas tsis raug yuav raug muab pov tseg, thiab cov pob ntawv raug yuav raug xa mus.
Txawm li cas los xij, qee cov pob ntawv 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 zoo li no yuav tsis raug xa lossis muab pov tseg thaum lub sijhawm xa mus, thiab lawv yuav khaws cia hauv qhov tsis muaj zog.(buffer), nws tsis tuaj yeem xa tawm.Thaum qhov tsis muaj puv, nws yuav ua rau lub qhov hloov pauv.Vim lub sij hawm no restarting lub transceiver los yog restarting lub hloov yuav ua rau cov kev sib txuas lus rov mus rau qhov qub.
