Cov teeb meem tshwm sim hauv kev teeb tsa thiab kev siv fiber ntau optic transceivers
Kauj Ruam 1: Ua ntej, koj puas pom tias qhov taw qhia ntawm fiber ntau transceiver lossis optical module thiab qhov taw qhia qhov chaw nres nkoj twisted nyob rau?
1.Yog qhov chaw nres nkoj kho qhov muag (FX) qhov taw qhia ntawm A transceiver yog nyob rau thiab qhov chaw nres nkoj kho qhov muag (FX) qhov taw qhia ntawm B transceiver tsis teeb, qhov txhaum yog nyob rau sab A transceiver: ib qho ua tau yog: A transceiver (TX) optical kis tau tus mob Qhov chaw nres nkoj tau tawg vim qhov chaw nres nkoj kho qhov muag (RX) ntawm B transceiver tsis tau txais lub teeb liab kho qhov muag.Lwm qhov muaj peev xwm yog tias muaj teeb meem nrog qhov txuas fiber ntau ntawm A transceiver (TX) qhov chaw nres nkoj optical, xws li lub teeb. jumper tawg.
2.Yog hais tias qhov chaw nres nkoj kho qhov muag (FX) qhov taw qhia ntawm lub transceiver tsis teeb, txiav txim siab seb qhov fiber ntau txuas yog cross-linked.Lub fiber jumper yog txuas mus rau qhov sib npaug thiab lwm qhov yog qhov sib txuas.
3.Qhov taw qhia twisted khub (TP) tsis teeb.Thov xyuas kom meej tias cov twisted khub cable yog faulty los yog txuas tsis raug.Thov siv qhov txuas txuas ntxiv los kuaj xyuas.(Txawm li cas los xij, qee qhov kev hloov pauv 'cov ntawv sib tw sib tw yuav tsum tau tos kom txog thaum qhov txuas fiber ntau qhib).
4.Qee lub transceivers muaj ob qhov chaw nres nkoj RJ45: (ToHUB) qhia tias cov kab txuas txuas txuas cov keyboards yog ib txoj kab ncaj nraim.(ToNode) qhia tias txoj kab txuas txuas txuas rau cov keyboards yog kab hla.
5.Qee lub transmitters muaj MPR hloov nyob rau sab: txoj kab kev sib txuas ntawm cov keyboards yog ib hom kab ncaj nraim.Qhov hloov DTE: txoj kab kev sib txuas ntawm cov keyboards yog hom kab hla.
Kauj ruam 2: Ntsuam xyuas seb puas muaj teeb meem nrog lub fiber jumper thiab cable?
1.Optical fiber kev twb kev txuas on-off nrhiav kom tau: siv laser teeb, hnub ci, thiab lwm yam rau illumination lub fiber jumper.Saib seb puas pom lub teeb nyob rau lwm yam kawg?Yog tias pom lub teeb pom kev, lub fiber jumper tsis tawg.
2.Cable break detection: siv laser teeb, hnub ci, illuminator rau illumination ntawm cable connector los yog coupler.Saib seb puas pom lub teeb nyob rau lwm yam kawg?Yog tias pom lub teeb pom kev, lub cable tsis tawg.
Kauj ruam 3: Puas yog ib nrab / puv duplex txoj kev tsis raug?
Qee qhov transceivers muaj FDX keyboards ntawm sab: puv duplex;HDX keyboards: ib nrab duplex.
Kauj Ruam 4: Siv lub ntsuas hluav taws xob kho qhov muag ntsuas ntsuas ntsuas
Lub zog luminous ntawm optical transceiver lossis optical module nyob rau hauv ib txwm muaj: multimode: -10db-18db;ib hom 20km: -8db–15db;ib hom 60km: -5db–12db Yog hais tias lub luminous hwj chim ntawm lub optical transceiver nyob nruab nrab ntawm -30db–45db, ces nws yuav raug txiav txim tias muaj teeb meem nrog no transceiver.
Optical transceivers yuav tsum tau them sai sai rau qhov teeb meem
Rau lub hom phiaj ntawm kev yooj yim, nws yog qhov zoo dua kom muaj lus nug thiab lus teb style, uas tuaj yeem ua tiav ntawm ib nrais muag.
1.Puas lub optical transceiver nws tus kheej txhawb nqa puv-duplex thiab ib nrab-duplex?
Qee cov chips ntawm lub khw tsuas tuaj yeem siv tag nrho-duplex ib puag ncig tam sim no, thiab tsis tuaj yeem txhawb nqa ib nrab-duplex.Yog tias koj txuas mus rau lwm hom kev hloov pauv (SWITCH) lossis hub (HUB), thiab nws siv ib nrab-duplex hom, nws yuav ua rau muaj kev tsis sib haum xeeb loj thiab pob ntawv poob.
2.Nws puas tau raug sim rau kev sib txuas nrog lwm cov fiber ntau optic transceivers?
Tam sim no, muaj ntau thiab ntau optical transceivers nyob rau hauv kev ua lag luam.Piv txwv li, yog tias qhov sib xyaw ua ke ntawm cov khoom sib txawv ntawm cov transceivers tsis tau sim ua ntej, nws tseem yuav ua rau pob ntawv poob, lub sijhawm xa mus ntev, thiab nrawm thiab qeeb.
3.Puas muaj cov cuab yeej kev nyab xeeb los tiv thaiv pob ntawv poob?
Qee cov tuam txhab siv cov ntaub ntawv hloov pauv hom txhawm rau txo cov nqi thaum tsim cov fiber ntau optic transceivers.Qhov loj tshaj qhov tsis zoo ntawm txoj kev no yog qhov kev sib kis tsis ruaj khov thiab pob ntawv poob, thiab qhov zoo tshaj plaws yog siv cov kab tsis siv neeg tsim, uas tuaj yeem tiv thaiv cov ntaub ntawv zoo. pob ntawv poob.
4.Tub kub adaptability?
Thaum siv fiber ntau optic transceiver nws tus kheej, nws yuav tsim kom muaj cua sov.Thaum qhov kub thiab txias siab dhau (tsis ntau tshaj 50 ° C), seb qhov fiber ntau optic transceiver ua haujlwm ib txwm yog qhov tsim nyog xav tau los ntawm cov neeg siv khoom!
5.Puas muaj tus qauv IEEE802.3u?
Yog hais tias lub optical transceiver ua tau raws li IEEE802.3 tus qauv, uas yog, lub sijhawm ncua sijhawm yog tswj ntawm 46 ntsis.Yog tias nws tshaj 46 me ntsis, qhov kev ncua deb kis los ntawm optical transceiver yuav luv.
6. Kev pab cuam tom qab muag:
Txhawm rau ua kom cov kev pabcuam tomqab muag tau teb sai thiab ntxov, nws raug nquahu kom cov neeg siv khoom yuav khoom fiber ntau optic transceivers raws li lub zog ntawm cov chaw tsim khoom, thev naus laus zis, lub koob npe nrov thiab lwm lub tuam txhab.
