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 obude obusetyenziswayo yi-1310nm kunye ne-1550nm. Nangona kunjalo, ngenxa yokuba akukho mgangatho udityanisiweyo wezizwe ngezizwe weemveliso ze-fiber-fiber transceiver, iimveliso zabavelisi abahlukeneyo zisenokungahambelani 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 se-fiber 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 kuthungelwano lwefayibha engundoqo okanye ezimbini; 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-double-fiber isebenzisa ii-cores ezimbini, enye yokuthumela kunye neyokwamkela, enye isiphelo sithumela 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 imo enye kuphela; 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.
