Ama-transceivers e-fiber opticalngokuvamile zisetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela. Ngesikhathi esifanayo, baphinde babamba iqhaza elikhulu ekusizeni ukuxhuma imayela lokugcina lemigqa yefiber optical kumanethiwekhi ezindawo zedolobha elikhulu kanye namanethiwekhi angaphandle. Indima ye.

Ukuhlukaniswa kwe-Fiber optic transceiver: ukuhlukaniswa kwemvelo

Imodi eyodwai-fiber optical transceiver: Ibanga lokudlulisela lamakhilomitha angama-20 ukuya kumakhilomitha ayi-120 I-Multi-mode optical fiber transceiver: ibanga lokudlulisela lamakhilomitha ama-2 ukuya kumakhilomitha ama-5 Isibonelo, amandla okudlulisa we-5km fiber optic transceiver ngokuvamile aphakathi kuka -20 kanye -14db, futhi ukuzwela okutholayo -30db, kusetshenziswa ubude begagasi obungu-1310nm; kuyilapho amandla okudlulisa e-fiber optic transceiver engu-120km ikakhulukazi ephakathi kuka--5 no-0dB, futhi ukuzwela okutholayo kungu--38dB, futhi kusetshenziswa ubude begagasi obungu-1550nm.

Ukuhlukaniswa kwe-Fiber optic transceiver: ukuhlukaniswa okudingekayo

I-single-fiber optical fiber transceiver: idatha eyamukelwe futhi yathunyelwa idluliselwa ngefayibha eDual-fiberi-fiber optical transceiver: idatha etholiwe futhi ethunyelwe idluliselwa ku-pair of optical fibers Njengoba igama lisho, imishini ye-fiber eyodwa ingasindisa uhhafu we-fiber optical, okungukuthi, ukwamukela nokuthumela idatha ku-fiber optical eyodwa, efaneleka kakhulu izindawo. lapho izinsiza ze-fiber optical ziqinile. Lolu hlobo lomkhiqizo lusebenzisa ubuchwepheshe be-wavelength division multiplexing, kanti ubude be-wavelength obusetshenzisiwe ngokuvamile bungu-1310nm no-1550nm. Kodwa-ke, ngenxa yokuthi alikho izinga elihlanganisiwe lamazwe ngamazwe lemikhiqizo ye-transceiver ye-fiber eyodwa, kungase kube nokungahambisani phakathi kwemikhiqizo yabakhiqizi abahlukene lapho ixhumeke. Ngaphezu kwalokho, ngenxa yokusetshenziswa kwe-wavelength division multiplexing, imikhiqizo ye-transceiver ye-single-fiber ngokuvamile inesici sokunciphisa isignali enkulu.

Izinga/izinga lokusebenza

I-100M Ethernet i-fiber optic transceiver: ukusebenza kungqimba olubonakalayo lwe-10/100M i-Ethernet fiber optic transceiver: ukusebenza kungqimba lwesixhumanisi sedatha Ngokusho kwezinga lokusebenza / izinga, lingahlukaniswa libe yi-10M eyodwa, i-100M fiber optic transceivers, i-10/100M i-adaptive fibre optic transceivers, i-1000M fiber optic transceivers, kanye ne-10/100/1000 i-adaptive transceivers. Phakathi kwazo, imikhiqizo ye-transceiver eyodwa ye-10M kanye ne-100M isebenza kungqimba olubonakalayo, futhi imikhiqizo ye-transceiver esebenza kulesi sendlalelo idlulisela idatha kancane kancane. Le ndlela yokudlulisela phambili inezinzuzo zejubane lokudlulisa ngokushesha, izinga eliphezulu lokubonisa ngale, nokubambezeleka okuphansi. Ilungele ukusetshenziswa kuzixhumanisi zesilinganiso esingaguquki. Ngesikhathi esifanayo, njengoba amadivaysi anjalo angenayo inqubo yokuxoxisana ngokuzenzakalela ngaphambi kokuxhumana okujwayelekile, ayahambisana Ukwenza kangcono mayelana nobulili nokuzinza.

Ukuhlukaniswa kwe-Fiber optic transceiver: ukuhlukaniswa kwesakhiwo

Ideskithophu (ezimele yodwa) i-fiber optic transceiver: imishini yeklayenti ezimele yodwa I-Rack-mounted (modular) optical fibre transceiver: efakwe ku-chassis enezikhala eziyishumi nesithupha, kusetshenziswa amandla aphakathi nendawo Ngokwesakhiwo, ingahlukaniswa ibe ideskithophu (isitendi). -yedwa) i-fiber optic transceivers kanye ne-rack-mounted fiber optic transceivers. I-transceiver yefiber optical yedeskithophu ifanele umsebenzisi oyedwa, njengokuhlangana nokuxhuma phezulu kweyodwashintshaephaseji. Ama-transceivers e-fiber optic afakwe kwi-rack (modular) afanele ukuhlanganisa abasebenzisi abaningi. Njengamanje, ama-racks amaningi afuywayo ayimikhiqizo ye-slot engu-16, okungukuthi, kufika ku-16 modular fiber optic transceivers ingafakwa ku-rack.

Ukuhlukaniswa kwe-Fiber optic transceiver: ukuhlukaniswa kohlobo lokuphatha

I-Ethernet optical fiber transceiver engalawulwa: xhuma futhi udlale, setha imodi yokusebenza yembobo kagesi ngokudayela kwehadiwe.shintshaUhlobo lokuphathwa kwenethiwekhi i-Ethernet fiber optic transceiver: ukwesekwa kokuphathwa kwenethiwekhi yenkampani yenethiwekhi

I-Optical fiber transceiver classification: ukuhlukaniswa kokuphathwa kwenethiwekhi

Ingahlukaniswa ngama-transceivers e-fiber optic angalawulwa kanye nama-transceivers e-fiber optic aphethwe yinethiwekhi. Iningi lama-opharetha lithemba ukuthi wonke amadivaysi akunethiwekhi yawo angaphathwa ukude. Imikhiqizo ye-Fiber optic transceiver, njengamaswishi kanyeimizila, zikhula kancane kancane kule ndlela. Ama-transceivers e-fiber optic angaxhunywa kunethiwekhi nawo angahlukaniswa abe yi-central office network management kanye nokuphathwa kwenethiwekhi yomsebenzisi. Ama-transceivers e-fiber optic angaphathwa yihhovisi elimaphakathi ikakhulukazi yimikhiqizo efakwe ngama-rack, futhi iningi lawo lithatha isakhiwo sokuphatha isigqila. Ngakolunye uhlangothi, imodyuli yokuphatha inethiwekhi enkulu idinga ukuvotela ulwazi lokuphatha inethiwekhi ku-rack yayo, futhi ngakolunye uhlangothi, idinga futhi ukuqoqa wonke ama-sub-racks wezinceku. Ulwazi olukunethiwekhi lube seluhlanganiswa futhi luhanjiswe kuseva yokuphatha inethiwekhi. Isibonelo, uchungechunge lwe-OL200 lwemikhiqizo ye-transceiver ye-fiber optical ephethwe yinethiwekhi ehlinzekwe yi-Wuhan Fiberhome Networks isekela uhlaka lokuphathwa kwenethiwekhi loku-1 (inkosi) + 9 (isigqila), futhi ingaphatha ama-transceiver efiber optical afika kwangu-150 ngesikhathi. Ukuphathwa kwenethiwekhi yohlangothi lomsebenzisi kungahlukaniswa ngezindlela ezintathu eziyinhloko: eyokuqala iwukusebenzisa iphrothokholi ethile phakathi kwehhovisi elimaphakathi nedivayisi yeklayenti. Iphrothokholi inesibopho sokuthumela imininingwane yesimo seklayenti ehhovisi elimaphakathi, futhi i-CPU yedivayisi yehhovisi elimaphakathi iphatha lezi zifunda. Ulwazi futhi uluthumele kuseva yokuphatha inethiwekhi; okwesibili ukuthi i-transceiver ye-fiber optical yehhovisi eliphakathi ingakwazi ukubona amandla optical ku-port optical, ngakho-ke uma kunenkinga endleleni ye-optical, amandla okukhanya angasetshenziswa ukuze anqume ukuthi inkinga iku-fiber optical noma ukwehluleka kwemishini yomsebenzisi; Okwesithathu ukufaka i-CPU yokulawula eyinhloko ku-fiber transceiver ohlangothini lomsebenzisi, ukuze uhlelo lokuphatha inethiwekhi lukwazi ukuqapha isimo sokusebenza semishini eseceleni yomsebenzisi ngakolunye uhlangothi, futhi ingakwazi nokubona ukucushwa okukude kanye nokuqalisa kabusha okukude. Phakathi kwalezi zindlela ezintathu zokuphatha inethiwekhi yohlangothi lwamakhasimende, ezokuqala ezimbili ziwukuqapha okukude kwemishini eseceleni kweklayenti, kanti eyesithathu iwukuphathwa kwangempela kwenethiwekhi okukude. Kodwa-ke, njengoba indlela yesithathu ingeza i-CPU ohlangothini lomsebenzisi, okwandisa nezindleko zemishini eseceleni yomsebenzisi, izindlela ezimbili zokuqala zinezinzuzo ezengeziwe ngokwenani. Njengoba opharetha bafuna ukuphathwa kwenethiwekhi yemishini eyengeziwe, kukholelwa ukuthi ukuphathwa kwenethiwekhi ye-fiber optic transceivers kuzoba okusebenzayo futhi okuhlakaniphile.

I-Fiber optic transceiver classification: ukuhlukaniswa kwamandla kagesi

I-transceiver ye-fiber optic eyakhelwe ngaphakathi: i-switching power supply eyakhelwe ngaphakathi ingumthombo wamandla we-carrier-grade; Ukunikezwa kwamandla kwangaphandle kwe-fiber optic transceiver: ugesi wangaphandle we-transformer usetshenziswa kakhulu emishinini yabantu.

Ukuhlukaniswa kwe-Fiber optic transceiver: ukuhlukaniswa kwendlela yokusebenza

Imodi ye-full-duplex isho ukuthi lapho ukuthunyelwa nokwamukelwa kwedatha kuhlukaniswa futhi kudluliselwa imigqa yokudlulisela emibili ehlukene, zombili izinhlangothi ekuxhumaneni zingathumela futhi zamukele ngesikhathi esisodwa. Imodi enjalo yokudlulisela iyisistimu egcwele i-duplex. Kumodi ye-duplex egcwele, isiphetho ngasinye sesistimu yokuxhumana ifakwe isidlulisi nomamukeli, ngakho-ke idatha ingalawulwa ukuze idluliselwe kuzo zombili izinkomba ngesikhathi esisodwa. Imodi ye-duplex egcwele ayidingishintshaisiqondiso, ngakho-ke akukho ukubambezeleka kwesikhathi okubangelwa ukusebenza kokushintsha. Imodi ye-half-duplex ibhekisela ekusetshenzisweni kolayini wokudlulisela ofanayo kukho kokubili ukwamukela nokuthumela. Nakuba idatha ingadluliselwa kuzo zombili izinkomba, izinhlangothi zombili azikwazi ukuthumela nokwamukela idatha ngesikhathi esisodwa. Le modi yokudlulisela i-half-duplex. Lapho imodi ye-half-duplex yamukelwa, isidlulisi nomamukeli ekugcineni ngakunye kohlelo lwezokuxhumana kudluliselwa entanjeni yokuxhumana ngokwamukela/ukuthumela.shintshato shintshaisiqondiso. Ngakho-ke, ukubambezeleka kwesikhathi kuzokwenzeka.
