I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye nemiqondiso yokubona ekude.Ngokweemfuno zayo, ihlulwe ngokukodwa kwi-fiber-fiber optical transceivers kunye ne-dual-fiber optical transceivers.Okulandelayo, siya kwazisa ngokweenkcukacha yintoni i-single-mode single-fiber / dual-fiber optical transceiver?Ngowuphi umahluko phakathi kwe-single-fiber-fiber kunye nemowudi enye yee-transceivers optical optical mode enye-nye?Ukuba unomdla, makhe sijonge!

Yintoni naimowudi enye-fiber optical transceiver?

I-single-mode single-fiber optical fiber transceiver, izixhobo ze-fiber enye zingagcina isiqingatha se-fiber optical, oko kukuthi, ukufezekisa ukwamkelwa kwedatha kunye nokuhanjiswa kwifiber enye ye-optical.

I-fiber optical fiber transceiver: Idatha efunyenweyo kwaye ithunyelwe ihanjiswa kwifiber optical.Njengoko igama libonisa, izixhobo ze-fiber enye zinokugcina isiqingatha se-fiber optical, oko kukuthi, ukufumana kunye nokuthumela idatha kwi-fiber optical fiber, efanelekileyo kakhulu kwiindawo apho izibonelelo zefiber optical ziqinile.Olu hlobo lwemveliso lusebenzisa itekhnoloji yolwahlulo lwe-wavelength multiplexing, kwaye uninzi lwamaza asetyenziswayo yi-1310nm kunye ne-1550nm.Nangona kunjalo, ngenxa yokuba akukho mgangatho udityanisiweyo wezizwe ngezizwe wemveliso ye-fiber-fiber transceiver, iimveliso zabenzi abahlukeneyo zinokungahambelani xa ziqhagamshelwe.Ukongezelela, ngenxa yokusetyenziswa kwe-wavelength division multiplexing, iimveliso ze-fiber-fiber transceiver ngokubanzi zineempawu zokunciphisa umqondiso omkhulu.Okwangoku, uninzi lwe-fiber optic transceivers kwimarike ziyimveliso yefiber ezimbini, ezikhulile kwaye zizinzile, kodwa zifuna iifiber ezininzi.

Yintoni naimowudi enye i-dual-fiber optical transceiver?

I-mode-single-fiber optical fiber transceiver, kunye ne-fiber-fiber bidirectional optical fiber transceiver zizixhobo zokuguqula i-photoelectric, enenzuzo yokugcina isiqingatha sefiber.

I-fiber-fiber bidirectional optical fiber transceiver iyisixhobo sokuguqula i-photoelectric esebenzisa iteknoloji ye-wavelength division multiplexing ukuthumela nokufumana idatha kwi-fiber optical, kunye nokuguqula izibonakaliso zombane zenethiwekhi kunye nezibonakaliso zokukhanya.I-fiber-fiber bidirectional optical fiber transceivers ziye zaziwa kakhulu kwiminyaka yakutshanje.Inzuzo kukuba inokugcina isiqingatha sefiber optical.Akukho mgangatho umanyeneyo wamazwe ngamazwe wokunqongophala kwesiqingatha sefiber optical.Iimveliso eziveliswe ngabavelisi abohlukeneyo zihlala zihambelana kwaye zinozinzo olubi kancinci kuneemveliso ezimbini zefayibha.Okwangoku, ii-fiber optic transceivers kwimarike zisalawulwa ziimveliso ezimbini zefiber.

Yintoni umahluko phakathiImowudi enye-ifayibha enye kunye nemowudi enye i-dual-fiber transceivers optical?

Imowudi enye yeemowudi ezininzi ixhomekeke kwintambo yokukhanya, ifayibha enye ifayibha ezimbini zibhekisa kwi-fiber-core transmission okanye i-two-core fiber transmission;Imowudi enye ibhekisa kusetyenziso lweentambo zokukhanya zemowudi enye, ii-transceivers zefiber enye zisebenzisa i-core enye kuphela, zombini iziphelo Zombini ziqhagamshelwe kulo ngundoqo, kwaye ii-transceivers kuzo zombini iziphelo zisebenzisa i-wavelengths eyahlukileyo, ngoko ke imiqondiso ye-optical inokudluliselwa kuyo. undoqo omnye.I-transceiver ye-fiber-fiber isebenzisa ii-cores ezimbini, enye yokuthumela kwaye enye yokwamkela, enye isiphelo sihambisa kwaye esinye isiphelo kufuneka sifakwe kwi-port eyamkelayo, oko kukuthi, iziphelo ezimbini kufuneka ziwele.

Kwisicelo esithile se-single-mode kunye ne-dual-mode, inani le-multi-mode liphezulu kunelo le-single-mode, ngokukodwa kuluhlu lwe-wiring olungaphantsi kwe-500m, i-multi-mode iyakwazi ukuhlangabezana, nangona intsebenzo ingekho kakuhle. njengemowudi enye.Imowudi enye isetyenziswa kwiindawo ezingaphezulu kwe-500m okanye kwiindawo ezineemfuno eziphezulu zebhanwidth, ubukhulu becala kwizicelo zentsimi ezinkulu ezifana nenqanaba leshishini.Ngenxa yokuzinza nokusebenza kweiimodyuli zefiber opticalzingcono kakhulu kunama-transceivers, kwizicelo zendlela enye kunye neemfuno eziphezulu zokusebenza, iinkampani ezimbalwa zisebenzisa i-transceivers, kodwa zisebenzisa ngokuthe ngqo iimodyuli endaweni yoko.

Ifayibha enye kunye nefayibha ezimbini ngokubanzi zinamazibuko amabini, kwaye amazibuko amabini osinga olubini asondelelene.Ziphawulwe nge-TX kunye ne-RX, enye yokuthumela kwaye enye yokwamkela, ekhethiweyo;izibuko ezimbini zefayibha enye ngokubanzi ziyi-P1, i-P2 ibonisa ukuba omabini amazibuko angathumela kwaye afumane ngokwahlukileyo, oko kukuthi, izibuko elinye lisetyenziselwa ukugqiba ukuthumela nokwamkela, ngoko kubizwa ngokuba yifayibha enye.I-transceivers optical TX kunye ne-RX imele ukufumana kunye nokudlulisa.Kukho iindidi ezimbini ze-transceivers optical: enye yimowudi enye kwaye enye imowudi ezimbini.Njengendlela enemizila enye kuphela, iimoto zisenokuxinana.Ukuba ngumgca wemigca emibini, iya kuba lula kakhulu, ngoko kuyacaca ukuba ii-transceivers zemowudi ezimbini zizinzile ngcono.

I-fiber enye ithetha ukuba ifayibha enye kuphela isetyenziselwa ukudibanisa ii-transceivers ezimbini.Ifayibha ezimbini ziqhelekile kwaye zifuna iintsinga ezimbini, kwaye ixabiso lefiber enye liphezulu kancinci.I-transceiver ye-multi-mode ifumana iindlela zokuhambisa ezininzi, umgama wokuhambisa ufutshane, kwaye i-transceiver ye-mode eyodwa ifumana kuphela imodi enye;umgama wothumelo mde ngokwentelekiso.Nangona i-multi-mode iyasuswa, kusekho izicelo ezininzi ekubekweni iliso kunye nokuhanjiswa komgama omfutshane ngenxa yexabiso eliphantsi.Ii-transceivers ze-multi-mode zihambelana ne-multi-mode optical fibers, kunye ne-mode-mode kunye ne-single-mode iyahambelana.Azinakuxutywa.
