Mathata a kopaneng ho kenya le ho sebelisa li-transceivers tsa fiber optic
Mohato oa 1: Taba ea pele, na ua bona hore na pontšo ea fiber transceiver kapa optical module le li-port tse sothehileng li teng?
1. Haeba letšoao la optical port (FX) la transceiver ea A le ntse le le teng 'me letšoao la optical port (FX) la B transceiver le sa bonesoa, phoso e ka lehlakoreng la A transceiver: monyetla o mong ke: Transceiver (TX) phetiso ea optical Kou e robehile hobane optical port (RX) ea B transceiver ha e fumane pontšo ea optical. Monyetla o mong ke hore ho na le bothata ba khokahanyo ena ea fiber ea A transceiver (TX) optical port, e kang leseli. jumper e robehile.
2.Haeba sesupo sa optical port (FX) sa transceiver se sa khantše, etsa qeto ea hore na khokahanyo ea fiber e hokahane.Fiber jumper e hokahane ka ho bapa 'me e' ngoe ke sefapano.
3.Letšoao le sothehileng (TP) ha le khantše.Ka kopo etsa bonnete ba hore thapo e sothehileng ea para e fosahetse kapa e hoketsoe hampe.Ka kopo sebelisa "continuity tester" ho hlahloba.(Leha ho le joalo, li-transceivers tse ling tse sothehileng li tlameha ho ema ho fihlela khokahanyo ea fiber e buloa).
4.Li-transceivers tse ling li na le likou tse peli tsa RJ45: (ToHUB) e bontša hore mohala oa khokahanyo o kopanyang li-switches ke mohala o otlolohileng.(ToNode) e bonts'a hore mohala oa khokahanyo o kopanyang li-switches ke sefapano.
5.Li-transmitters tse ling li na le phetoho ea MPR ka lehlakoreng le leng: mohala oa khokahanyo o kopanyang li-switches ke mokhoa o otlolohileng oa mohala.Tlhaloso ea DTE: mohala o kopanyang li-switches ke mokhoa oa ho tšela.
Mohato oa 2: Hlahloba hore na ho na le bothata ka fiber jumper le cable?
1.Optical fiber connection on-off discover: sebelisa laser toche, khanya ea letsatsi, joalo-joalo ho khantša fiber jumper.Bona hore na ho na le leseli le bonahalang ka lehlakoreng le leng?Haeba ho na le leseli le bonahalang, fiber jumper ha e robehe.
2.Cable break discovery: sebelisa laser flashlight, sunlight, illuminator ho khantša sehokelo sa cable kapa coupler.Bona hore na ho na le leseli le bonahalang ka lehlakoreng le leng?Haeba ho na le leseli le bonahalang, thapo ha e robehe.
Mohato oa 3: Na mokhoa oa halofo/fell duplex o fosahetse?
Li-transceivers tse ling li na le li-switches tsa FDX ka lehlakoreng: duplex e feletseng;Liphetoho tsa HDX: halofo ea duplex.
Mohato oa 4: Ho sebelisa lisebelisoa tsa optical power meter ho lemoha
Matla a khanyang a transceiver optical kapa optical module tlas'a maemo a tloaelehileng: multimode: -10db-18db;mokhoa o le mong 20km: -8db–15db;single mode 60km: -5db–12db Haeba matla a khanyang a transceiver optical a pakeng tsa -30db-45db, joale ho ka ahloloa hore ho na le bothata ka transceiver ena.
Li-transceivers tsa optical li lokela ho ela hloko litaba
Molemong oa ho nolofatsa, ho molemo ho ba le mokhoa oa ho botsa lipotso le oa karabo, o ka finyelloang ka pono.
1.Na transceiver ea optical ka boeona e tšehetsa full-duplex le half-duplex?
Li-chips tse ling 'marakeng li ka sebelisa tikoloho ea duplex e felletseng hajoale,' me ha li khone ho ts'ehetsa halofo ea duplex.Haeba o hokela ho mefuta e meng ea li-switch (SWITCH) kapa hub (HUB), 'me e sebelisa mokhoa oa halofo ea duplex, e tla baka likhohlano tse tebileng le tahlehelo ea pakete.
2.Na e lekoa bakeng sa ho hokahana le li-transceivers tse ling tsa fiber optic?
Hona joale, ho na le li-transceivers tse ngata tsa optical 'marakeng.Ka mohlala, haeba ho lumellana ha mefuta e fapaneng ea li-transceivers ha ho e-s'o hlahlojoe pele, ho tla fella ka tahlehelo ea liphutheloana, nako e telele ea phetisetso, le ka potlako le butle.
3.Na ho na le sesebelisoa sa polokeho ho thibela tahlehelo ea pakete?
Baetsi ba bang ba sebelisa mokhoa oa ho fetisa boitsebiso e le ho fokotsa litšenyehelo ha ho etsoa li-transceivers tsa fiber optic.Tlhaloso e kholo ka ho fetisisa ea mokhoa ona ke hore phetisetso ha e tsitsa le ho lahleheloa ke pakete, 'me se molemo ka ho fetisisa ke ho sebelisa moralo oa mohala oa buffer, o ka qobang data ka mokhoa o sireletsehileng. tahlehelo ea pakete.
4.Ho ikamahanya le maemo?
Ha fiber optic transceiver ka boeona e sebelisoa, e tla hlahisa mocheso o phahameng.Ha mocheso o phahame haholo (e seng ho feta 50 ° C), hore na transceiver ea fiber optic e sebetsa ka tloaelo ke ntlha e lokelang ho nahanoa ke bareki!
5.Na ho na le maemo a IEEE802.3u?
Haeba transceiver ea optical e kopana le maemo a IEEE802.3, ke hore, nako ea ho lieha e laoloa ho 46 bits.Haeba e feta li-bits tse 46, sebaka se fetisoang ke transceiver ea optical se tla khutsufatsoa.
6.After-thekiso tšebeletso:
E le ho etsa hore tšebeletso ea morao-rao e arabe ka potlako le pele, ho kgothaletswa hore bareki ba reke li-transceivers tsa fiber-optic ho ea ka matla a moetsi, theknoloji, botumo le lik'hamphani tse ling.
