Ii-fiber optic transceiveriyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasignali kagesi asontekile ahamba ibanga elifushane namasignali okubona amabanga amade.Ibuye ibizwe ngokuthi i-photoelectric converter ezindaweni eziningi. Umkhiqizo uvame ukusetshenziswa endaweni yangempela yenethiwekhi lapho ikhebula le-Ethernet lingakwazi ukumboza futhi i-fiber optical kufanele isetshenziselwe ukunweba ibanga lokudlulisela, futhi ngokuvamile ibekwe ohlelweni lokusebenza lwesendlalelo sokufinyelela. inethiwekhi yendawo yedolobha elikhulu le-fiber optical fiber;ngesikhathi esifanayo, kusiza ukuxhuma imayela lokugcina le-fiber optical edolobheni.Inethiwekhi yendawo kanye nenethiwekhi yangaphandle nakho kudlale indima enkulu.
Kalula nje, indima ye-fiber optic transceiver ukuguqulwa okuhlangene phakathi kwamasignali optical kanye namasignali kagesi.Isignali ye-optical iwukungena kusuka ku-port optical, futhi isignali kagesi iphuma echwebeni likagesi (i-interface evamile ye-crystal ye-RJ45), futhi ngokuphambene nalokho.Inqubo icishe ibe: ukuguqula amasignali kagesi abe amasignali optical, uwadlulisele ngokusebenzisa imicu optical, bese iguqula amasignali okubonayo abe amasignali kagesi ngakolunye uhlangothi, bese iwaxhuma kumarutha, amaswishi nezinye izinto zokusebenza.
Yiziphi izigaba ze-fiber optic transceivers
Ama-engeli ahlukene wokubuka enza abantu babe nokuqonda okuhlukile kwama-transceiver e-fiber optic:
Isibonelo, ngokwezinga lokudlulisela, ihlukaniswe yaba yi-10M eyodwa, i-100M fiber optic transceivers,I-10/100M i-adaptive fibre optic transceiverskanye ne-1000M fiber optic transceivers;
Ngokusho kwemodi yokusebenza, ihlukaniswe ngama-transceivers e-fiber optic asebenza kungqimba olubonakalayo kanye nama-transceivers e-fiber optic asebenza kungqimba lwesixhumanisi sedatha;
Ngokombono wesakhiwo, ihlukaniswe yaba ideskithophu (izimele yodwa) i-fiber optic transceivers kanye ne-rack-mounted fibre optic transceivers;
Ngokwemicu ehlukene yokufinyelela, kunamagama amabili: i-multi-mode fibre transceiver kanye ne-single-mode fiber transceiver.
Ngaphezu kwalokho, kukhona i-fiber optic transceivers eyodwa-fiber kanyei-dual-fiber fiber optic transceivers, ama-transceiver e-fiber optic awakhelwe ngaphakathi amandla kanye nama-transceivers optic optic amandla angaphandle, kanye nama-transceivers e-fiber optic aphethwe kanye nama-transceivers e-fiber optic angalawulwa.
Ama-transceivers e-Fiber optic aphula umkhawulo wamamitha angu-100 wezintambo ze-Ethernet ekudluliselweni kwedatha, athembele ekushintsheni ama-chips asebenza kahle kakhulu kanye nama-buffers amakhulu, kuyilapho efezekisa ngempela ukuthunyelwa okungavimbeli nokusebenza kokushintsha, futhi inikeza ithrafikhi elinganiselayo, ukuhlukaniswa kwezingxabano kanye Ukutholwa kwephutha neminye imisebenzi kuqinisekisa ukuvikeleka okuphezulu nokuzinza phakathi nokudluliswa kwedatha.
Luphi uhla lokusetshenziswa kwama-transceivers e-fiber optic
Empeleni, i-transceiver ye-fiber optical iqeda kuphela ukuguqulwa kwedatha phakathi kwemidiya ehlukene, engakwazi ukubona ukuxhumana phakathi kokushintsha okubili noma amakhompyutha ngaphakathi kwe-0-120Km, kodwa isicelo sangempela sinokunwetshwa okwengeziwe.
- Qaphela ukuxhumana phakathiamaswishi.
- Qaphela ukuxhumana phakathi kweswishi nekhompyutha.
- Qaphela ukuxhumana phakathi kwamakhompyutha.
- Ukudlulisa okudluliswayo: Uma ibanga langempela lokudlulisela lidlula ibanga elivamile lokudlulisela le-transceiver, ikakhulukazi uma ibanga langempela lokudlulisela lidlula i-120Km, uma izimo zesayithi zivuma, sebenzisa ama-transceivers angu-2 ngokudlulisela emuva kuya emuva noma ukuguqulwa kokukhanya kuya ku-optical. i-relay iyisixazululo esingabizi kakhulu.
- Ukuguqulwa kwemodi eyodwa-multi-mode: Uma uxhumano lwe-fiber yemodi eyodwa-multi-mode ludingeka phakathi kwamanethiwekhi, isiguquli semodi eyodwa-multi-mode singasetshenziswa ukuxhuma, okuxazulula inkinga yokuguqulwa kwe-fiber yemodi eyodwa-multi-mode.
- I-Wavelength division multiplexing transmission: Uma izinsiza zekhebula le-fiber optical ebangeni elide zinganele, ukuze kwandiswe izinga lokusebenzisa ikhebula le-optical futhi kuncishiswe izindleko, i-transceiver kanye ne-multiplexer ye-wavelength division ingasetshenziswa ndawonye ukuze kudluliselwe iziteshi ezimbili. ulwazi ngepheya efanayo yemicu yokubona.
