Fibre optique ya transibre ikoreshwa mubisanzwe mubidukikije aho insinga za Ethernet zidashobora gupfuka kandi zigomba gukoresha fibre optique kugirango yongere intera yoherejwe.Mubisanzwe biherereye murwego rwo kugera kumurongo mugari wa metero nini, kandi bikoreshwa cyane mubikorwa bitandukanye byo gukurikirana no kubungabunga umutekano.Ariko byanze bikunze tuzahura nibibazo bimwe na bimwe murwego rwo gukoresha fibre optique, none twabikemura dute nyuma yo guhura nikibazo.
Kunanirwa bisanzwe hamwe nibisubizo bya fibre optique
1. Ni ubuhe bwoko bw'ihuza bukoreshwa mugihe icyambu cya RJ45 gihujwe nibindi bikoresho?
Impamvu: Icyambu cya RJ45 cya transceiver gihujwe n'ikarita ya PC ya PC (ibikoresho bya terefone ya DTE) ukoresheje guhuza ibice, kandi HUB cyangwa SWITCH (ibikoresho byitumanaho rya DCE) bikoreshwa kumurongo ugereranije.
2. Niyihe mpamvu ituma urumuri rwa TxLink ruzimya?
Impamvu: a.Huza ibice bitari byo;b.Guhuza nabi hagati ya kristu ihindagurika umutwe hamwe nigikoresho, cyangwa ubuziranenge bwibintu byombi;c.Igikoresho ntabwo gihujwe neza.
3. Niyihe mpamvu ituma urumuri rwa TxLink rudahumbya ariko rugumaho nyuma ya fibre ihujwe neza?
Ijwi ryumwimerere: a.Ubusanzwe ikosa riterwa nintera ndende yoherejwe;b.Guhuza ikarita y'urusobe (ihujwe na PC).
4. Niyihe mpamvu ituma urumuri rwa Fxlink ruzimya?
Impamvu: a.Umugozi wa fibre uhujwe nabi.Uburyo bwiza bwo guhuza ni TX-RX, RX-TX cyangwa uburyo bwa fibre nibeshya;b.Intera yoherejwe ni ndende cyane cyangwa igihombo kiri hagati ni kinini cyane, kirenze igihombo cyizina cyibicuruzwa.Igisubizo ni: Fata ingamba zo kugabanya igihombo hagati cyangwa kuyisimbuza intera ndende;c.Ubushyuhe bwo gukora bwa optique fibre transceiver ni ndende cyane.
5. Niyihe mpamvu ituma urumuri rwa Fxlink rudahumbya ariko rugumaho nyuma ya fibre ihujwe neza?
Impamvu: Iri kosa muri rusange riterwa nintera yo kohereza ari ndende cyane cyangwa igihombo cyo hagati kikaba kinini cyane, kirenze igihombo cyizina cyibicuruzwa.Igisubizo nukugabanya igihombo kiri hagati cyangwa kugisimbuza intera ndende yoherejwe.
6. Nakora iki niba amatara atanu yose yaka cyangwa ibipimo nibisanzwe ariko ntibishobora kwanduzwa?
Impamvu: Mubisanzwe, amashanyarazi hanyuma utangire kugarura ibisanzwe.
7. Ubushyuhe bwibidukikije bwa transceiver ni ubuhe?
Impamvu: Moderi ya fibre optique yibasiwe cyane nubushyuhe bwibidukikije.Nubwo ifite ibyuma byunguka byikora, nyuma yubushyuhe burenze urwego runaka, imbaraga za optique ya module ya optique iragabanuka kandi ikagabanuka, bityo bikananiza ubwiza bwikimenyetso cya optique kandi bigatera igihombo Igipimo kizamuka, ndetse kigahagarara. ihuriro ryiza;(muri rusange ubushyuhe bwo gukora bwa optique ya fibre optique irashobora kugera kuri 70 ℃)
8. Ni mu buhe buryo guhuza n'amasezerano y'ibikoresho byo hanze?
Impamvu: 10 / 100M ya fibre transibers ifite uburebure buringaniye nkuburebure bwa 10 / 100M, mubisanzwe ntibirenza 1522B cyangwa 1536B.Iyo switch ihujwe ku biro bikuru ishyigikira protocole idasanzwe (nka Ciss 'ISL) Ipaki yimbere iriyongera (Ciss ISL packet overhead is 30Bytes), irenze imipaka yo hejuru yuburebure bwikigero cya fibre transceiver kandi ikajugunywa na ,, byerekana igipimo kinini cyangwa cyatsinzwe igipimo cyigihombo.Muri iki gihe, MTU yigikoresho cya terefone igomba guhinduka Mu gice cyohereza, rusange IP packet hejuru ni 18 bytes, naho MTU ni 1500 bytes.Kugeza ubu, abakora ibikoresho byitumanaho byo murwego rwohejuru bafite protocole y'imbere.Mubisanzwe, uburyo butandukanye bwo gupakira bukoreshwa mukongera IP packet hejuru.Niba amakuru ari 1500 bytes Nyuma yipaki ya IP, ingano yipaki ya IP izarenga 18 hanyuma ikajugunywa), kuburyo ingano yipaki yoherejwe kumurongo ishimishije kumipaka yibikoresho byurusobe kuburebure bwikigero.1522 bytes yipaki yongeyeho VLANtag.
9. Nyuma yuko chassis imaze igihe ikora, kuki amakarita amwe ananirwa gukora neza?
Impamvu: Amashanyarazi ya chassis yambere itanga uburyo bwa relay.Amashanyarazi adahagije hamwe no gutakaza umurongo munini nibibazo nyamukuru.Nyuma ya chassis imaze igihe ikora, amakarita amwe ntashobora gukora mubisanzwe.Iyo amakarita amwe akuweho, amakarita asigaye akora bisanzwe.Nyuma ya chassis imaze igihe kinini ikora, okiside ihuza itera igihombo kinini.Aya mashanyarazi arenze amabwiriza.Urwego rusabwa rushobora gutuma ikarita ya chassis idasanzwe.Diode ifite imbaraga nyinshi Schottky ikoreshwa mugutandukanya no kurinda amashanyarazi ya chassis, kunoza imiterere yumuhuza, no kugabanya kugabanuka kwamashanyarazi biterwa numuzunguruko hamwe nu muhuza.Muri icyo gihe, ingufu z'amashanyarazi zitangwa z'amashanyarazi ziriyongera, ibyo bigatuma rwose itangwa ry'amashanyarazi ryoroha kandi rikagira umutekano, kandi rikarushaho kuba ryiza ku bisabwa n'imirimo y'igihe kirekire idahagarara.
10. Ni ibihe bikorwa impuruza ihuza itanga kuri transceiver?
Impamvu: Transceiver ifite imikorere yo gutabaza (guhuza).Iyo fibre ihagaritswe, izahita igaruka ku cyambu cy'amashanyarazi (ni ukuvuga, icyerekezo ku cyambu cy'amashanyarazi nacyo kizasohoka).Niba uhindura afite imiyoboro yubuyobozi, bizagaragarira kuri switch ako kanya.Porogaramu yo gucunga imiyoboro.
