Ngaba ifayibha yamehlo ingaguqula intambo yenethiwekhi? Ifayibha ye-Optical luhlobo lwefiber yeglasi ye-optical, ehambisa izibonakaliso ze-optical kwaye ayikwazi ukudibanisa ngokuthe ngqo kwintambo yenethiwekhi. Kufuneka kusetyenziswe izixhobo zokuguqula i-photoelectric ukuguqula imiqondiso ye-optical kwimiqondiso yenethiwekhi. Izixhobo eziqhelekileyo zokuguqula i-photoelectric ziquka indluizixhobo zekati zefiber optical, i-fiber optical transceiver kunye ne-Optical switch.
1.Isixhobo semodem yefiber optic yasekhaya
Iimodem zeFiber opticzikwabizwa ngokuba ziimodem zefiber optic. Umsebenzi wayo oyintloko kukwenza ukuguqulwa kwesignali. Sisixhobo esisetyenziselwa ukuhanjiswa kwenethiwekhi.”I-Fiber optic modem” idla ngokusetyenziselwa uthumelo lomgama odlula i-20KM kunye nezantya ezingaphaya kwe-2M. Izixhobo zothumelo lwe-Optical ezifana ne-SDH / PDH ziyafuneka phakathi. Kwimeko yokudluliselwa, imodem ye-optical isetyenzisiweyo, eyona nto ifakwe kuzo zombini iziphelo ze-fiber optical kwaye iguqule idatha edlulisiweyo phakathi kwezibonakaliso zombane kunye neempawu zokukhanya. Xa i-broadband ye-optical ifakwe ekhaya, iimodem ze-optical zisetyenziselwa ukuguqula iimpawu ukuze iikhomputha kunye nezinye izixhobo zikwazi ukuqaphela le miqondiso. Ngoku iimodem ezibonakalayo ziqhagamshela iifowuni, iiTV, ibroadband,iirothakunye nokufikelela kwi-Intanethi ngaphandle kwamacingo.
I-2.Optical fiber transceiver
I-Optical fiber transceiverluhlobo lwesixhobo sokuguqula umbane esitshintsha umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokubona ekude. Isignali ye-optical igalelo kwi-port optical kunye nesignali yombane iphuma kwi-port yombane (i-RJ45 crystal head interface). Inkqubo yokuguqula imiqondiso yombane ibe yimiqondiso ye-optical kwaye idlulisele ngeefiber optical. Kwelinye icala, imiqondiso ye-optical iguqulwa ibe yimiqondiso yombane, ize iqhagamshelwe kuyoiirotha, iiswitshikunye nezinye izixhobo.
Ngokomgama wothumelo, zinokwahlulwa zibe yimodi enye kunye ne-multi-mode transceivers. ① I-transceiver yefayibha yendlela enye: umgama wothumelo uphakathi kweekhilomitha ezingama-20 kunye ne-120 yeekhilomitha; ②I-Multi-mode optical fiber transceiver: umgama wothumelo uphakathi kweekhilomitha ezi-2 kunye neekhilomitha ezi-5.
Kwinkqubo yokudlulisa, i-fiber optic transceivers kufuneka isetyenziswe ngababini, ifanelekile kumgama ongaphezu kweemitha ezili-100, ukukhanya kwesalathisi ngasinye kubonisa intsingiselo eyahlukileyo, i-1000-xa ivuliwe, imele i-1000M izinga, i-100-xa ivuliwe, imele. Ireyithi ye-100M; FX- Xa ivuliwe, ithetha ukuba i-pigtail ixhunyiwe, kwaye xa ikhanya, ithetha ukuba idatha idluliswa; FX LINK / ACT-xa ivuliwe, ithetha ukuba intambo yenethiwekhi ixhunyiwe, kwaye xa iyadanyaza, ithetha ukuba idatha iyahanjiswa; xa ivuliwe, ithetha ukuba intambo yamandla ixhunyiwe; I-TX LINK/ACT—Xa ivuliwe, imele ireyithi ye-duplex epheleleyo, kwaye xa icinyiwe, imele i-half-duplex.
3.Umbane wokufotatshintsha
Ukutshintsha kwamehloluhlobo lwesixhobo sokuhanjiswa kwenethiwekhi. Umahluko phakathi kwayo kunye nesiqhelotshintshakukuba isebenzisa intambo ye-fiber optic njenge-transmission medium.Isebenzisa i-fiber channel enezinga eliphezulu logqithiso lokudlulisela ukudibanisa nenethiwekhi yomncedisi okanye inethiwekhi ye-SAN yangaphakathi ukwenza yonke Inethiwekhi inomthamo omkhulu kakhulu, ngoko izinga lokudluliselwa ngokukhawuleza kwaye isakhono sokuchasa ukungenelela sinamandla.
Kukho i-2 optical 2 yombane, i-4 optical 2 yombane, i-8 optical 2 yombane kunye nezinye i-photoelectric.iiswitshi. I-4 optical 2 yombane ithetha i-4 i-fiber optical input port kunye ne-2 i-RJ45 i-port ye-network port output, enokuxhasa i-100M kunye ne-Gigabit networks, efanelekileyo kumashishini amakhulu Ukuhanjiswa kwe-Multiple optical fiber.
