Fiber optic transceivers feem ntau yog siv nyob rau hauv lub network tiag tiag ib puag ncig qhov twg Ethernet cables tsis tuaj yeem npog thiab yuav tsum siv cov fibers kho qhov muag kom ntev qhov kev sib kis.Lawv feem ntau yog nyob rau ntawm txheej nkag ntawm broadband cheeb tsam hauv cheeb tsam network, thiab tau siv dav hauv ntau yam kev saib xyuas thiab kev nyab xeeb.Tab sis peb yuav inevitably ntsib qee qhov teeb meem hauv cov txheej txheem ntawm kev siv fiber ntau optic transceivers, yog li peb yuav daws nws li cas tom qab ntsib qhov teeb meem.
Kev ua tsis tiav thiab kev daws teeb meem ntawm optical fiber transceivers
1. Dab tsi ntawm kev sib txuas yog siv thaum lub transceiver RJ45 chaw nres nkoj txuas nrog lwm yam khoom siv?
Yog vim li cas: RJ45 chaw nres nkoj ntawm lub transceiver txuas nrog PC network card (DTE cov ntaub ntawv davhlau ya nyob twg cov cuab yeej) siv tus ntoo khaub lig-twisted khub, thiab HUB lossis SWITCH (DCE cov ntaub ntawv sib txuas lus khoom siv) yog siv rau cov kab sib txuas.
2. Dab tsi yog vim li cas lub teeb TxLink raug kaw?
vim: a.Txuas tus khub twisted tsis ncaj ncees lawm;b.Kev sib cuag tsis zoo ntawm cov twisted khub siv lead ua lub taub hau thiab lub cuab yeej, lossis qhov zoo ntawm cov twisted khub nws tus kheej;c.Cov cuab yeej txuas tsis zoo.
3. Dab tsi yog vim li cas lub teeb TxLink tsis ntsais tab sis nyob twj ywm tom qab cov fiber ntau txuas zoo?
Original suab: a.Qhov txhaum feem ntau yog tshwm sim los ntawm kev sib kis ntev;b.Compatibility nrog lub network card (txuas mus rau lub PC).
4. Dab tsi yog vim li cas vim li cas lub teeb Fxlink tsis raug?
vim: a.Lub fiber cable txuas tsis raug.Txoj kev sib txuas raug yog TX-RX, RX-TX lossis hom fiber ntau tsis raug;b.Qhov kev sib kis tau ntev dhau los lossis qhov kev poob nruab nrab yog qhov loj dhau, dhau qhov nominal poob ntawm cov khoom no.Txoj kev daws teeb meem yog : Siv cov kev ntsuas los txo qhov kev poob nruab nrab lossis hloov nws nrog kev sib kis ntev dua;c.Kev khiav hauj lwm kub ntawm optical fiber transceiver yog siab dhau.
5. Dab tsi yog vim li cas vim li cas lub teeb Fxlink tsis ntsais tab sis nyob twj ywm tom qab fiber ntau txuas zoo?
Ua rau: Qhov kev ua txhaum no feem ntau yog tshwm sim los ntawm qhov kev sib kis tau ntev dhau los lossis qhov kev poob nruab nrab yog loj dhau, tshaj qhov poob ntawm cov khoom no.Txoj kev daws teeb meem yog kom txo qis qhov poob nruab nrab lossis hloov nws nrog qhov sib kis ntev dua transceiver.
6. Kuv yuav ua li cas yog tias tsib lub teeb yog tag nrho los yog qhov taw qhia zoo li qub tab sis tsis tuaj yeem kis tau?
Yog vim li cas: Nquag, fais fab tuag thiab rov pib dua kom rov zoo li qub.
7. Qhov kub thiab txias ntawm lub transceiver yog dab tsi?
Ua rau: Lub optical fiber module tau cuam tshuam zoo heev los ntawm qhov kub thiab txias.Txawm hais tias nws muaj qhov ua tau zoo hauv qhov tsis siv neeg nce Circuit Court, tom qab qhov kub siab tshaj qhov ntau, lub zog kho qhov muag ntawm qhov kho qhov muag module cuam tshuam thiab txo qis, yog li ua rau qhov tsis zoo ntawm cov teeb liab optical network tsis muaj zog thiab ua rau pob ntawv poob tus nqi nce, txawm tias disconnecting. qhov txuas optical;(feem ntau qhov kev khiav hauj lwm kub ntawm lub optical fiber module tuaj yeem ncav cuag 70 ℃)
8. Yuav ua li cas sib raug zoo nrog cov khoom siv sab nraud kev pom zoo?
Yog vim li cas: 10/100M fiber ntau transceivers muaj tib lub thav duab ntev txwv li 10/100M keyboards, feem ntau tsis ntau tshaj 1522B lossis 1536B.Thaum qhov hloov pauv txuas ntawm lub chaw ua haujlwm hauv nruab nrab txhawb qee cov kev cai tshwj xeeb (xws li Ciss 'ISL) Cov pob ntawv nyiaj siv ua haujlwm tau nce ntxiv (Ciss ISL pob ntawv nyiaj siv ua haujlwm yog 30Bytes), uas tshaj qhov txwv sab saud ntawm tus ncej ntev ntawm cov fiber ntau transceiver thiab muab pov tseg los ntawm nws, xav txog qhov siab lossis tsis ua tiav pob ntawv poob tus nqi.Lub sijhawm no, MTU ntawm cov khoom siv davhlau ya nyob twg yuav tsum tau hloov kho Hauv chav xa khoom, cov pob ntawv IP dav dav yog 18 bytes, thiab MTU yog 1500 bytes.Tam sim no, cov tuam txhab tsim khoom siv kev sib txuas lus high-end muaj cov txheej txheem hauv network.Feem ntau, cov txheej txheem pob ntawv cais yog siv los ua kom cov pob ntawv IP nce ntxiv.Yog tias cov ntaub ntawv yog 1500 bytes Tom qab IP pob ntawv, qhov loj ntawm IP pob ntawv yuav dhau 18 thiab muab pov tseg), yog li qhov loj ntawm pob ntawv xa mus rau ntawm kab yog txaus siab rau lub network ntaus ntawv txwv ntawm tus ncej ntev.1522 bytes ntawm pob ntawv tau ntxiv VLANtag.
9. Tom qab lub chassis tau ua haujlwm rau lub sijhawm, vim li cas qee daim npav tsis ua haujlwm zoo?
Yog vim li cas: Thaum ntxov chassis fais fab mov txais hom relay.Cov khoom siv hluav taws xob tsis txaus thiab cov kab poob loj yog cov teeb meem loj.Tom qab lub chassis tau ua haujlwm rau lub sijhawm, qee daim npav tsis tuaj yeem ua haujlwm ib txwm.Thaum qee daim npav raug rho tawm, daim npav seem ua haujlwm ib txwm ua.Tom qab lub chassis tau ua haujlwm ntev, lub connector oxidation ua rau lub connector loj poob.Cov khoom siv hluav taws xob no poob dhau qhov kev cai.Qhov xav tau ntau yam yuav ua rau daim npav chassis txawv txav.High-power Schottky diodes yog siv los cais thiab tiv thaiv lub chassis fais fab hloov, txhim kho daim ntawv ntawm lub connector, thiab txo cov fais fab mov poob los ntawm kev tswj Circuit Court thiab connector.Nyob rau tib lub sijhawm, lub zog rov ua dua ntawm cov khoom siv hluav taws xob tau nce ntxiv, uas ua rau cov khoom siv hluav taws xob rov qab tau yooj yim thiab nyab xeeb, thiab ua rau nws tsim nyog rau cov kev xav tau ntawm kev ua haujlwm ntev tsis muaj kev cuam tshuam.
10. Dab tsi ua haujlwm ntawm lub tswb txuas rau ntawm lub transceiver?
Yog vim li cas: Lub transceiver muaj qhov txuas tswb muaj nuj nqi (linkloss).Thaum lub fiber ntau raug txiav, nws yuav cia li rov qab mus rau qhov chaw nres nkoj hluav taws xob (uas yog, qhov taw qhia ntawm qhov chaw nres nkoj hluav taws xob kuj yuav tawm mus).Yog tias qhov hloov pauv muaj kev tswj hwm network, nws yuav cuam tshuam rau qhov hloov tam sim ntawd.Network tswj software.
