I-Optical fiber transceiveriwuhlobo lwemishini yokuguqula i-Ethernet transmission medium eshintshanisa amasignali e-Ethernet kagesi nawe-optical, futhi ibizwa nangokuthi isiguquli se-photoelectric. I-fiber optical edlulisela idatha kunethiwekhi ihlukaniswe nge-multi-mode optical fiber kanye ne-single-mode optical fiber. Okulandelayo, ake sibheke ukuthi iyini i-transceiver ebonakalayo enemodi eyodwa nokuthi iyini i-multi-mode optical transceiver. Ake sibheke ukusetshenziswa kwama-transceiver optical kumaphrojekthi wokuqapha amavidiyo enethiwekhi ephezulu!

I-transceiver ye-fiber optical yemodi eyodwa: ibanga lokudlulisela lamakhilomitha angama-20 ukuya kumakhilomitha ayi-120,

I-Multimode optical fibre transceiver: ibanga lokudlulisela livamise ukuba ngamakhilomitha ama-2 kuye kwangama-5.

Kusukela kuhlelo lokusebenza lwenethiwekhi, ngenxa yokuthi i-multi-mode optical fiber ayikwazi ukuhambisa amabanga amade, ngokuvamile ingasetshenziselwa ukuxhumana ngaphakathi naphakathi kwezakhiwo, njengokusungulwa kwamanethiwekhi angaphakathi ekhampasi ezikoleni.

Uchungechunge lwe-fiber optic transceiver yemodi eyodwa

Ngokuthuthuka kobuchwepheshe, i-fiber yemodi eyodwa isiqalile ukungena emisebenzini yenethiwekhi yebanga elide (kusuka kumakhilomitha ambalwa ukuya ngaphezu kwamakhilomitha ayi-100), futhi umfutho wayo wokuthuthuka uyashesha kakhulu. Phakathi neminyaka embalwa, izicelo ezisezingeni eliphezulu sezingenile ezindlini zabantu abavamile. Namuhla, amanye amakhasimende abalulekile asebenzisa ama-optical fibre transceivers (okuthiwa imodi ye-FTTH, i-fiber-to-the-home) ngokuqondile lapho evula inethiwekhi ekhaya. Ukusetshenziswa kwama-optical fibre transceivers ekuxhumaneni nokuxhumana sekuyindlela ejwayeleke kakhulu yokusakaza nethelevishini ukuze kuthuthukiswe izinsiza ezingeziwe.

I-transceiver ye-fiber optical yemodi eyodwa eyodwa

Okubizwa ngokuthi i-dual-fiber optical transceiver isebenzisa imicu emibili ye-optical (eyodwa yokwamukela neyodwa yokudlulisa), isethi yama-transceivers optical ukuze ibone ukuguqulwa kwamasignali kagesi kumasignali optical, amasignali optical bese emva kwalokho amasignali kagesi. Ukuvela kwama-transceivers optical fiber kuyixazulula ngokuphumelelayo inkinga yezintambo zenethiwekhi. Inkinga yebanga lokudlulisela.

I-transceiver ye-fiber optical yemodi eyodwa eyodwa

Okubizwa ngokuthi i-dual-fiber optical transceiver isebenzisa imicu emibili ye-optical (eyodwa yokwamukela neyodwa yokudlulisa), isethi yama-transceivers optical ukuze ibone ukuguqulwa kwamasignali kagesi kumasignali optical, amasignali optical bese emva kwalokho amasignali kagesi. Ukuvela kwama-transceivers optical fiber kuyixazulula ngokuphumelelayo inkinga yezintambo zenethiwekhi. Inkinga yebanga lokudlulisela.Ngaso leso sikhathi, amaza amaza amabili asetshenziselwa ukudlulisa amasignali -1310nm kanye ne-1550nm, okusho ukuthi, umkhawulo owodwa usebenzisa i-1310nm wavelength ukuthumela, kanye ne-1550nm wavelength ukuthola amasignali ngesikhathi esifanayo, usebenzisa ubuchwepheshe be-wavelength division multiplexing. , ukuxazulula ngempumelelo inkinga yokuphazanyiswa kwesignali.

Ngokuvamile, uma i-fiber optic transceiver ibekwe ekamelweni lekhompyutha, isisombululo sithambekele kakhulu ku-centralized fiber optic transceiver rack. Khetha lolu hlobo lwe-fiber optic transceiver, okokuqala, ikhwalithi yesakhiwo izinzile, futhi okwesibili, uhlobo lweSakhiwo se-modular, ukubekwa okuphakathi kwama-fiber optic transceivers kungenziwa ngokubeka ama-rack ekamelweni lekhompyutha. Isibonelo, i-14-slot rack ingabeka ama-transceiver we-fiber optic angu-14 ngesikhathi, futhi yamukela ukufakwa kwe-plug-in, eguquguqukayo ekunakekeleni nasekushintsheni ngaphandle kokuphazanyiswa. Ukusebenza okuvamile kwamanye ama-transceivers.
