1.Ke eng afiber optic transceiver?
Optical fiber transceiver e boetse e bitsoa photoelectric converter, e leng Ethernet transmission media converter unit e fapanyetsanang sebaka se sekhuts'oane se sothehileng mats'oao a motlakase le mats'oao a mahlo a malelele.
Li-angles tse fapaneng tsa ho shebella li etsa hore batho ba be le kutloisiso e fapaneng ea li-transceivers tsa fiber optic, joalo ka10M e le 'ngoe, 100M fiber optic transceivers, 10/100M li-transceivers tsa fiber optic tse feto-fetohang le1000M li-transceivers tsa fiber opticho latela sekhahla sa phetiso; li arotsoe ka mekhoa ea mosebetsi. Li-transceivers tsa fiber optic tse sebetsang karolong ea 'mele le li-transceivers tsa fiber optic tse sebetsang lera la khokahanyo ea data; ho ea ka pono ea sebopeho, li arotsoe ka li-desktop (e ikemetseng) li-transceivers tsa fiber optic le li-transceivers tsa fiber optic tse nang le rack-mounted; ho latela phapang ea fiber ea phihlello Ho na le mabitso a mabeli bakeng sa multi-mode optical fiber transceiver le single-mode optical fiber transceiver.
Ho phaella moo, ho na le li-transceivers tsa optic tse nang le fiber e le 'ngoe le li-transceivers tse peli-fiber optic, li-transceivers tsa fiber optic tse hahiloeng ka matla le li-transceivers tsa matla a ka ntle a fiber optic, hammoho le li-transceivers tsa fiber optic tse laoloang le li-transceivers tsa fiber optic tse sa laoloang. Li-transceivers tsa fiber optic li senya moeli oa limithara tse 100 tsa lithapo tsa Ethernet phetisong ea data, li itšetlehile ka lisebelisoa tse phahameng tsa ts'ebetso le li-buffers tse kholo, ha li ntse li finyella ts'ebetso e sa thibeleng le ho fetola ts'ebetso, e boetse e fana ka sephethephethe se leka-lekaneng, ho itšehla thajana le likhohlano.

3.To sebelisa transceiver ea fiber ea optical
Kenyelletsong, rea tseba hore ho na le mekhahlelo e mengata e fapaneng ea li-transceivers tsa fiber optic, empa ha e le hantle, tlhokomelo e ngata e lefshoa ho lihlopha tse khetholloang ke li-connectors tse fapaneng tsa fiber: SC connector fiber optic transceiver le ST connector fiber optic transceiver. .
Ha u sebelisa li-transceivers tsa fiber optic ho hokahanya lisebelisoa tse fapaneng, u tlameha ho ela hloko likou tse fapaneng tse sebelisoang.
1. Ho hokahanya ha fiber optic transceiver ho lisebelisoa tsa 100BASE-TX (switjha, setsi):
Netefatsa hore bolelele ba thapo e sothehileng ha e fete limithara tse 100;
Kopanya ntlha e le 'ngoe ea para e sothehileng ho sekepe sa RJ-45 (Uplink port) ea transceiver ea fiber optic,' me e 'ngoe ho ea ho RJ-45 port (e tloaelehileng koung) ea sesebelisoa sa 100BASE-TX (switjha, khubu).
2. Ho hokahanya ha fiber optic transceiver ho thepa ea 100BASE-TX (karete ea marang-rang):
Netefatsa hore bolelele ba thapo e sothehileng ha e fete limithara tse 100;
Kopanya pheletsong e le 'ngoe ea para e sothehileng ho koung ea RJ-45 (100BASE-TX port) ea fiber optic transceiver, le pheletsong e' ngoe ho ea koung ea RJ-45 ea karete ea marang-rang.
3. Khokahano ea fiber optic transceiver ho 100BASE-FX:
Netefatsa hore bolelele ba fiber optical ha bo fete sebaka sa sebaka se fanoeng ke lisebelisoa;
Qetello e 'ngoe ea fiber e hokahane le sehokelo sa SC / ST sa transceiver ea fiber optic,' me pheletso e 'ngoe e hokahane le sehokelo sa SC / ST sa sesebelisoa sa 100BASE-FX.
Ntho e 'ngoe e lokelang ho eketsoa ke hore basebelisi ba bangata ba nahana ha ba sebelisa li-transceivers tsa fiber optic: hafeela bolelele ba fiber bo le ka har'a sebaka se seholo se tšehetsoeng ke fiber ea mofuta o le mong kapa fiber e mengata, e ka sebelisoa ka tloaelo. Ha e le hantle, ena ke kutloisiso e fosahetseng. Kutloisiso ena e nepahetse ha feela lisebelisoa tse hokahaneng e le lisebelisoa tse felletseng tsa duplex. Ha ho na le lisebelisoa tsa halofo ea duplex, sebaka sa phetisetso ea fiber optical se lekanyelitsoe.
4.Molao-motheo oa ho reka optical fiber transceiver
Joalo ka sesebelisoa sa sehokelo sa marang-rang, optical fiber transceiver ke mosebetsi oa eona o ka sehloohong ke mokhoa oa ho hokahanya data ea mekha e 'meli ka mokhoa o se nang moeli. Ka hona, re tlameha ho nahana ka ho lumellana ha eona le tikoloho e potolohileng, hammoho le botsitso le ho tšepahala ha lihlahisoa tsa eona, ho fapana le hoo: ho sa tsotellehe hore na theko e tlaase hakae, e ke ke ea sebelisoa!
1. Na e tšehetsa duplex e feletseng le halofo ea 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 li hokahane le mefuta e meng eali-switches (PHETHA) kapa li-hubs (HUB), 'me e sebelisa mokhoa oa halofo ea duplex, ka sebele e tla baka likhohlano tse tebileng le tahlehelo.
2. Na u lekile khokahano le li-transceiver tse ling tsa optical?
Hajoale, ho na le li-transceivers tsa fiber optic tse ntseng li eketseha 'marakeng. Haeba ho lumellana ha li-transceivers tsa mefuta e fapaneng ha ho e-s'o hlahlojoe esale pele, ho tla boela ho baka tahlehelo ea pakete, nako e telele ea phetisetso, le lebelo la tšohanyetso le ho lieha.
3. Na ho na le sesebelisoa sa polokeho ho thibela tahlehelo ea pakete?
E le ho fokotsa litšenyehelo, bahlahisi ba bang ba sebelisa "Register data transmission mode" ha ba etsa li-transceivers tsa fiber optic. Bothata bo boholo ka ho fetisisa ba mokhoa ona ke ho se tsitse le ho lahleheloa ke pakete nakong ea phetisetso. Molemo ka ho fetisisa ke ho sebelisa moralo oa potoloho ea buffer. E ka qoba tahlehelo ea pakete ea data ka mokhoa o sireletsehileng.
4. Ho ikamahanya le maemo a mocheso?
Fiber optic transceiver ka boeona e tla hlahisa mocheso o phahameng ha e sebelisoa. Ha mocheso o le holimo haholo (ka kakaretso ha o fete 85 ° C), na transceiver ea fiber optic e sebetsa ka tloaelo? Mocheso o phahameng o lumelletsoeng oa ho sebetsa ke ofe? Bakeng sa sesebelisoa se hlokang ts'ebetso ea nako e telele, ntho ena e bohlokoa hore re e ele hloko!
5.Na e lumellana le maemo a IEEE802.3u?
Haeba transceiver ea optical fiber e kopana le maemo a IEEE802.3, ke hore, ho lieha le nako e laoloa ho 46bit, haeba e feta 46bit, ho bolela hore sebaka sa phetisetso ea optical fiber transceiver se tla khutsufatsoa! !
