Xa iiprojekthi zangoku ezibuthathaka zidibana nokuhanjiswa komgama omde, iifiber optics zihlala zisetyenziswa. Ngenxa yokuba umgama wothumelo lwefiber optical mde kakhulu, ngokubanzi, umgama wothumelo lwefiber yemowudi enye ungaphezulu kweekhilomitha ezili-10, kwaye umgama wothumelo lwefiber yeendlela ezininzi ungafikelela kwiikhilomitha ezi-2.
Kuthungelwano lwefiber optic, sihlala sisebenzisa i-fiber optic transceivers. Ke, ukudibanisa njani i-fiber optic transceivers? Makhe sijonge kunye.
Okokuqala, indima ye-fiber optic transceivers
① I-transceiver ye-fiber optical inokwandisa umgama wokuhanjiswa kwe-Ethernet kwaye yandise i-radius ye-Ethernet.
② I-transceiver yefiber optical cantshintshaphakathi kwe-10M, i-100M okanye i-1000M ye-Ethernet ujongano lombane kunye ne-optical interface.
③ Ukusebenzisa i-fiber optic transceivers ukwakha uthungelwano kunokugcina utyalo-mali lwenethiwekhi.
④ Ii-transceivers ze-fiber optical zenza uqhagamshelwano phakathi kweeseva, abaphindayo, ii-hubs, ii-terminals kunye nee-terminals ngokukhawuleza.
⑤ I-transceiver ye-fiber optical ine-microprocessor kunye ne-diagnostic interface, enokubonelela ngolwazi oluhlukeneyo lwedatha yokusebenza kwekhonkco.
Okwesibini, yeyiphi i-transceiver enayo i-optical transceiver kwaye iyifumana kweyiphi?
Xa usebenzisa i-optical fiber transceivers, abahlobo abaninzi baya kuhlangabezana nale mibuzo:
1.Ngaba ii-transceivers zefiber optical kufuneka zisetyenziswe ngababini?
2.Ingaba i-transceiver yefiber optical yahlulwe yaba enye yokwamkela kunye neyokuhambisa? Okanye ngaba zimbini kuphela ii-transceivers ezibonakalayo ezinokusetyenziswa njengeperi?
3. Ukuba i-transceivers ye-fiber optical kufuneka isetyenziswe ngababini, ngaba kuyimfuneko ukuba i-brand kunye nemodeli efanayo? Okanye ngaba kukho naziphi na iimpawu ezinokusetyenziswa ngokudibeneyo?
Impendulo: Ii-transceivers ze-fiber optic zisetyenziswa ngokubanzi ngababini njengezixhobo zokuguqula i-photoelectric, kodwa kunokwenzeka ukudibanisa i-fiber optic transceivers kunye nefiber.iiswitshi, i-fiber optic transceivers kunye ne-SFP transceivers. Ngokomgaqo, ngokude nje i-optical transmission wavelength iyafana Ifomathi ye-signal encapsulation iyafana kwaye zombini zixhasa iprotocol ethile ukufezekisa unxibelelwano lwefiber optical.
Ngokuqhelekileyo, i-mode-mode-double-fiber (iifiber ezimbini zifunekayo kunxibelelwano oluqhelekileyo) i-transceivers ayihlulwanga kwi-transmitting end kunye nesiphelo sokufumana, kwaye ingasetyenziselwa nje ngokuba ibonakala ngababini.
Kuphela i-fiber-fiber transceiver (ifiber enye iyadingeka kunxibelelwano oluqhelekileyo) iya kuba nesiphelo sokudlulisa kunye nesiphelo sokufumana.
Ngamanye amazwi, amazinga ahlukeneyo (i-100M kunye ne-Gigabit) kunye ne-wavelengths eyahlukeneyo (1310nm kunye ne-1300nm) ayikwazi ukunxibelelana. Ukongezelela, nokuba i-fiber transceiver enye kunye ne-fiber ezimbini ze-brand efanayo zidibene, akunakwenzeka ukunxibelelana omnye nomnye. Iyasebenzisana.
Ke umbuzo ngulo, yintoni i-fiber transceiver enye kwaye yintoni i-fiber transceiver ezimbini? Yintoni umahluko phakathi kwabo?
Yintoni i-fiber-fiber transceiver? Yintoni i-dual-fiber transceiver?
I-transceiver ye-fiber enye ibhekiselele kwintambo yokukhanya yendlela enye. I-transceiver ye-fiber enye isebenzisa kuphela i-core enye kwaye zombini iziphelo zixhunyiwe kulo ngundoqo. Ii-transceivers kuzo zombini iziphelo zisebenzisa i-wavelengths eyahlukileyo ye-optical, ngoko ke ziyakwazi ukuhanjiswa kwisignali enye yokukhanya.
I-dual-fiber transceiver isebenzisa ii-cores ezimbini, enye yokudluliselwa kunye neyokwamkela, kwaye enye isiphelo kufuneka ifakwe kwelinye icala, kwaye iziphelo ezimbini kufuneka zigqitywe.
1.I-fiber transceiver enye
I-fiber-fiber transceiver kufuneka isebenzise zombini umsebenzi wokudlulisa kunye nomsebenzi wokufumana. Isebenzisa itekhnoloji yolwahlulo lwe-wavelength yokuphindaphinda ukuhambisa kunye nokufumana imiqondiso emibini ye-optical kunye ne-wavelengths eyahlukeneyo kwifiber enye ye-optical.
Ngoko ke, i-transceiver ye-single-fiber ye-fiber idluliselwa nge-fiber optical fiber, ngoko ke ukukhanya okugqithisiweyo kunye nokufumana ukukhanya kuhanjiswa nge-fiber core ngexesha elifanayo. Kule meko, ukufezekisa unxibelelwano oluqhelekileyo, kufuneka kusetyenziswe amaza amabini okukhanya kokukhanya.
Ngoko ke, imodyuli ye-optical ye-single-mode single-fiber transceiver inamaza amabini okukhanya okukhutshiweyo, ngokuqhelekileyo i-1310nm / 1550nm. Ngale ndlela, kukho iiyantlukwano phakathi kweziphelo ezimbini zeetransceivers:
I-transceiver kwelinye icala ithumela i-1310nm kwaye ifumana i-1550nm.
Esinye isiphelo sikhupha i-1550nm kwaye sifumana i-1310nm.
Ke kulungele abasebenzisi ukwahlula, kwaye ngokubanzi basebenzise oonobumba endaweni.
I-A-terminal (1310nm / 1550nm) kunye ne-B-terminal (1550nm / 1310nm) yavela.
Abasebenzisi kufuneka basebenzise ukubhanqa kwe-AB, hayi uqhagamshelo lwe-AA okanye lwe-BB.
Isiphelo se-AB sisetyenziselwa kuphela ii-fiber optic transceivers.
I-2.I-transceiver yefayibha ezimbini
I-transceiver ye-fiber-dual-fiber ine-port ye-TX (i-port yokudlulisa) kunye ne-RX port (i-port yokufumana). Omabini amazibuko asasaza kubude obufanayo be-1310nm, kwaye ulwamkelo lukwayi-1310nm. Ke ngoko, iifiber ezimbini ezihambelanayo ezisetyenziswa kwi-wiring ziqhagamshelwe.
3. Ukwahlula njani i-fiber transceiver enye kwi-fiber transceiver ezimbini?
Okwangoku kukho iindlela ezimbini zokwahlula ii-transceivers zefayibha enye ukusuka kwi-dual-fiber transceivers.
① Xa i-transceiver ebonakalayo ifakwe kunye nemodyuli ye-optical, i-transceiver ebonakalayo ihlukaniswe ibe yi-fiber-fiber transceiver kunye ne-fiber-fiber transceiver ngokwenani lee-cores ze-jumper ye-fiber edibeneyo. Umgca we-fiber optical jumper exhunywe kwi-fiber-fiber transceiver (ekunene) i-fiber core, ejongene nokuthumela kunye nokufumana idatha; I-linearity yi-cores ezimbini. Omnye undoqo unoxanduva lokuhambisa idatha kwaye enye ingundoqo inoxanduva lokufumana idatha.
②Xa i-transceiver ye-fiber optical ingenayo imodyuli ye-optical embedded, kuyimfuneko ukuhlukanisa phakathi kwe-fiber transceiver enye kunye ne-transceiver ye-fiber ephindwe kabini ngokwemodyuli ye-optical efakiweyo. Xa imodyuli ye-fiber bidirectional optical ifakwe kwi-transceiver ye-fiber optical, oko kukuthi, i-interface luhlobo olulula, i-fiber optical transceiver yi-fiber-fiber transceiver (umfanekiso ochanekileyo); xa imodyuli ye-fiber bidirectional optical ifakwe kwi-transceiver ye-fiber optical, Oko kukuthi, xa i-interface luhlobo lwe-duplex, le-transceiver yi-transceiver ye-fiber-fiber (umfanekiso osekhohlo).
Okwesine, isalathisi kunye nokudibanisa kwe-transceiver fiber optical
1.Isalathisi se-optical fiber transceiver
Kwisalathiso se-transceiver yefiber optical, sinenqaku elidlulileyo elinikezelwe kulo mxholo.
Apha siphinda sityelela ngomfanekiso ukuze siwucacise ngakumbi.
