I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye nemiqondiso yokubona ekude. Ikakhulu yahlulwe ibe yi-fiber-fiber optical transceivers kunye ne-dual-fiber optical transceivers ngokweemfuno zabo Okulandelayo, siza kwazisa ngokweenkcukacha ukuba yintoni i-single-fiber-fiber / dual-fiber optical transceiver? Ngowuphi umahluko phakathi kwe-single-fiber-fiber kunye nemowudi enye yee-transceivers zefayibha ezimbini? Bahlobo abanomdla, masijonge!
Yintoni imowudi enye-fiber optical transceiver?
I-mode-single-fiber optical fiber transceiver, izixhobo ze-fiber enye zingagcina isiqingatha se-fiber optical, oko kukuthi, ukufumana idatha kunye nokuhanjiswa kwifiber enye.
I-fiber optical fiber transceiver enye: Idatha efunyenweyo kwaye idluliselwe idluliselwe kwi-fiber optical fiber. Njengoko igama lithetha, izixhobo ze-fiber enye zinokugcina isiqingatha se-fiber optical, oko kukuthi, ukufumana kunye nokuthumela idatha kwi-fiber enye, efanelekileyo kakhulu kwiindawo apho izixhobo zefiber ziqinile. Olu hlobo lwemveliso lusebenzisa itekhnoloji ye-wavelength division multiplexing, kwaye i-wavelengths esetyenziswayo ubukhulu becala yi-1310nm kunye ne-1550nm. Nangona kunjalo, ngenxa yokuba akukho mgangatho udityanisiweyo wamazwe ngamazwe wemveliso ye-fiber-fiber transceiver, iimveliso zabavelisi abahlukeneyo zisenokungahambelani xa ziqhagamshelwe. Ukongeza, ngenxa yokusetyenziswa kwe-wavelength division multiplexing, iimveliso ze-fiber-fiber transceiver ngokubanzi zineempawu zokunciphisa umqondiso omkhulu. Okwangoku, uninzi lwee-transceivers zefiber optical kwimarike zimveliso ezimbini-fiber. Iimveliso ezinjalo zikhulile kwaye zizinzile, kodwa zifuna i-fibers optical ngakumbi.
Yintoni imowudi enye ye-dual-fiber optical transceiver?
I-mode-single-fiber optical transceiver, i-fiber-fiber bidirectional optical transceiver uhlobo lwesixhobo sokuguqula i-photoelectric, inzuzo kukugcina isiqingatha se-fiber optical.
I-fiber-fiber bidirectional optical fiber transceiver sisixhobo sokuguqula i-photoelectric esisebenzisa i-wavelength division multiplexing iteknoloji ukuhambisa kunye nokufumana idatha kwi-fiber optical enye kunye nokuguqula izibonakaliso zombane zenethiwekhi kunye neempawu ezibonakalayo. Ifayibha enye ye-bidirectional fiber optic transceivers sele idumile kwiminyaka yakutshanje. Inzuzo kukuba inokugcina isiqingatha se-fiber optical, kwaye ukungabikho kwesiqingatha se-fiber optical kukuba okwangoku akukho mgangatho odibeneyo wamazwe ngamazwe. Iimveliso eziveliswe ngabavelisi abohlukeneyo zihlala zihambelana kwaye azinzanga kancinci kuneemveliso ezimbini zefayibha. Okwangoku, ii-fiber optic transceivers kwimarike zisalawulwa ziimveliso ezimbini zefiber.
Yintoni umahluko phakathi kwe-single-fiber-fiber kunye nemowudi enye yee-transceivers zefayibha ezimbini?
I-multimode yemodi enye ixhomekeke kwintambo yokukhanya. Ifayibha enye enefayibha ezimbini ibhekisa kuthungelwano lwefayibha ye-fiber ene-core-core optical fiber transmission; imowudi enye ibhekisa ekusebenziseni intambo yefiber yendlela enye. Zombini ziqhagamshelwe kule ngundoqo, kwaye ii-transceivers kuzo zombini iziphelo zisebenzisa i-wavevel optical ezahlukeneyo, ngoko ke ziyakwazi ukuhambisa imiqondiso ye-optical kumbindi omnye. I-transceiver-fiber-fiber isebenzisa ii-cores ezimbini, enye ukuthumela kunye nomnye ukufumana, kwaye enye isiphelo sisiphelo sokuthumela kwaye esinye isiphelo kufuneka sifakwe kwi-port eyamkelayo, oko kukuthi, iziphelo ezimbini kufuneka ziwele.
Kwizicelo ezithile, imowudi enye-imowudi ye-multi-mode iphezulu kunemowudi enye, ngokukodwa kuluhlu lwe-wiring olungaphantsi kwe-500m, i-multi-mode sele idibene, nangona ukusebenza kungahambi kakuhle njengenye. -imowudi. Imowudi enye isetyenziswa kwindawo engaphezulu kwe-500m okanye iimfuno ze-bandwidth ephezulu, ubukhulu becala kwiindawo ezinkulu ezifana nezicelo zomgangatho weshishini. Ngenxa yokuba ukuzinza kokusebenza kunye nokusebenza kweemodyuli ze-fiber optical zingcono kakhulu kune-transceivers, kwiindawo zesicelo esisodwa kunye neemfuno eziphezulu zokusebenza, iinkampani ezimbalwa ziya kusebenzisa i-transceivers, kodwa zisebenzisa ngokuthe ngqo iimodyuli endaweni yoko. Kukho abavelisi abambalwa bee-analog transceivers kunye namaxabiso aphezulu.
Ifayibha enye kunye nefayibha ezimbini ngokubanzi zinamazibuko amabini, kwaye amazibuko amabini osinga olumbini asondelelene elinye. Ziphawulwe TX, RX, enye transmit kwaye enye yamkela, ngokulandelelanayo. Amazibuko amabini efayibha enye ngokubanzi ayi-P1. I-P2 ibonisa ukuba zombini izibuko zinokuthunyelwa kwaye zifumaneke ngokwahlukileyo, oko kukuthi, izibuko elinye lisetyenziselwa ukuthumela nokwamkela, ngoko libizwa ngokuba yifayibha enye. I-transceivers optical TX kunye ne-RX imele ukufumana kunye nokuthumela. Kukho iindidi ezimbini zee-transceivers zamehlo: enye yimowudi enye kwaye enye imowudi-mbini, kanye njengohola wendlela unokuxinana kuphela ukuba kukho umgca omnye kuphela, kodwa igudile kakhulu ukuba iyilayini ephindwe kabini, kucacile ukuba ukuzinza kommkeli wemowudi ezimbini Inqaku elilungileyo.
Ifayibha enye ludibaniso lwefiber enye phakathi kweetransceiver ezimbini, ifayibha ezimbini zixhaphake kakhulu, kufuneka usebenzise iintsinga ezimbini, ixabiso lefiber enye liphezulu kancinci. I-transceiver ye-multi-mode ifumana iindlela zokuhambisa ezininzi, umgama wokuhambisa ufutshane, kwaye i-transceiver ye-mode eyodwa ifumana imo enye kuphela; umgama wothumelo mde ngokwentelekiso. Nangona i-multi-mode ichithwa, kodwa ngenxa yexabiso eliphantsi, kusekho ezininzi ezisetyenziselwa ukubeka iliso kunye nokuhanjiswa kwexesha elifutshane. Ii-transceivers ze-multi-mode zihambelana ne-multi-mode optical fibers, i-single-mode kunye ne-single-mode iyahambelana, kwaye ayinakuxutywa.
