Ingabe i-optical fibre ingakwazi ukuguqula ikhebuli yenethiwekhi? I-Optical fiber iwuhlobo lwe-optical glass fiber, edlulisela amasignali optical futhi ayikwazi ukuxhunywa ngokuqondile kukhebuli yenethiwekhi. Idinga ukusebenzisa imishini yokuguqula ugesi wesithombe ukuze iguqule amasiginali okubona abe amasignali enethiwekhi. Imishini evamile yokuguqula ugesi wesithombe ihlanganisa indluimishini yekati ye-fiber optical, i-optical fiber transceiver kanye ne-Optical switch.

1.Imishini yemodemu ye-fiber optic yasekhaya

I-Fiber optic modemzibizwa nangokuthi i-fiber optic modem. Umsebenzi wayo oyinhloko ukwenza ukuguqulwa kwesignali. Kuyidivayisi edluliswayo esetshenziselwa ukudluliswa kwenethiwekhi.”I-Fiber optic modem” ivamise ukusetshenziselwa amabanga okudlulisela angaphezu kuka-20KM kanye nesivinini esingaphezu kuka-2M. Imishini yokudlulisa amehlo efana ne-SDH/PDH iyadingeka phakathi nendawo. Endabeni yokudlulisela, imodemu ye-optical isetshenziswa, efakwe ngokuyinhloko kuzo zombili iziphetho ze-fiber optical futhi iguqula idatha edlulisiwe phakathi kwamasignali kagesi namasignali optical. Uma i-broadband ebonakalayo ifakiwe ekhaya, amamodemu abonakalayo asetshenziselwa ukuguqula amasignali ukuze amakhompyutha nezinye izisetshenziswa zikwazi ukubona lezi zimpawu. Manje amamodemu abonakalayo axhuma amafoni, ama-TV, i-broadband,imizilakanye nokufinyelela ku-inthanethi okungenantambo.

I-2.Optical fiber transceiver

I-Optical fiber transceiveriwuhlobo lwemishini yokuguqula i-photoelectric eshintshanisa amasignali kagesi asontekile ahamba ibanga elifushane kanye namasignali okubona amabanga amade. Isignali ye-optical ifakiwe kusuka ku-optical port futhi isignali kagesi iphuma ku-port kagesi (i-RJ45 crystal head interface). Inqubo iwukuguqula amasignali kagesi abe amasignali optical futhi adlulisele ngokusebenzisa imicu optical. Ngakolunye uhlangothi, amasignali optical aguqulwa abe amasignali kagesi, bese exhunywa kuimizila, amaswishinezinye izinto zokusebenza.

Ngokwebanga lokudlulisela, zingahlukaniswa ngama-transceivers emodi eyodwa kanye namamodi amaningi. ①I-transceiver ye-fiber optical yemodi eyodwa: ibanga lokudlulisela liphakathi kwamakhilomitha angu-20 namakhilomitha angu-120; ②I-multi-mode optical fiber transceiver: ibanga lokudlulisela liphakathi kwamakhilomitha angu-2 namakhilomitha angu-5.

Enqubweni yokudlulisela, ama-fiber optic transceivers kumele asetshenziswe ngababili, afanele amabanga angaphezu kwamamitha ayi-100, ukukhanya kwenkomba ngakunye kumele incazelo ehlukile, i-1000-uma ivuliwe, imele isilinganiso esingu-1000M, i-100-uma ivuliwe, imele 100M isilinganiso; FX- Uma ivuliwe, kusho ukuthi i-pigtail ixhunyiwe, futhi uma ibaneka, kusho ukuthi idatha iyadluliselwa;FX LINK/ACT—uma ivuliwe, kusho ukuthi intambo yenethiwekhi ixhunyiwe, futhi nini liyakhanya, kusho ukuthi idatha iyadluliselwa; uma ivuliwe, kusho ukuthi intambo yamandla ixhunyiwe; I-TX LINK/ACT— -Uma ivuliwe, imelela isilinganiso se-duplex egcwele, futhi lapho icishiwe, imele i-half-duplex.

3.Ugesi wezithombeshintsha

I-Optical switchluhlobo lwemishini yokudlulisa inethiwekhi. Umehluko phakathi kwayo nokujwayelekileshintshaukuthi isebenzisa intambo ye-fiber optic njengendlela yokudlulisa.Isebenzisa ishaneli yefayibha enezinga eliphezulu lokudlulisela ukuxhuma nenethiwekhi yeseva noma inethiwekhi yangaphakathi ye-SAN ukuze yenze yonke Inethiwekhi inomkhawulokudonsa omkhulu kakhulu, ngakho izinga lokudlulisela liyashesha futhi ikhono lokulwa nokugxambukela linamandla.

Kukhona 2 optical 2 kagesi, 4 optical 2 kagesi, 8 optical 2 kagesi kanye nezinye photoelectric.amaswishi. I-4 optical 2 kagesi isho izimbobo zokufaka ze-fiber optical ezingu-4 kanye nokukhishwa kwembobo yenethiwekhi engu-2 RJ45, engasekela amanethiwekhi angu-100M kanye ne-Gigabit, afanele amabhizinisi amakhulu Ukuhanjiswa kwe-Multiple optical fiber.
