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 embindini.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 zidibanisa iifowuni, iiTV, i-broadband, ii-routers kunye nokufikelela kwi-Intanethi engenazintambo.

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.Ngakolunye uhlangothi, izibonakaliso ze-optical ziguqulwa zibe yimpawu zombane, kwaye ziqhagamshelwe kwii-routers, utshintsho kunye 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;TX LINK/ACT—Xa ivuliwe, imele ireyiti ephindwe kabini, kwaye xa icinyiwe, imele isiqingatha se-duplex.

3.Ukutshintsha kombane

Ukutshintsha kwamehloluhlobo lwesixhobo sokuhanjiswa kwenethiwekhi.Umahluko phakathi kwayo kunye nokutshintsha okuqhelekileyo kukuba isebenzisa intambo ye-fiber optic njenge-transmission medium.Isebenzisa i-fiber channel enezinga eliphezulu lokuhambisa ukudibanisa nenethiwekhi yomncedisi okanye inethiwekhi yangaphakathi ye-SAN ukwenza yonke Inethiwekhi ine-bandwidth enkulu kakhulu, ngoko izinga losulelo lukhawuleza kwaye amandla okuchasana nokuphazamiseka anamandla.

Kukho i-2 optical 2 yombane, i-4 optical 2 yombane, i-8 optical 2 yombane kunye nezinye izitshintshi ze-photoelectric.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.
