Ukuhlelwa kwee-transceivers zefiber optic

Ukuhlelwa ngefayibha enye/iifiber ezininzi

I-fiber optical transceiver enye:

I-fiber optical transceiver enye luhlobo olukhethekileyo lwe-transceiver optical efuna kuphela i-fiber enye ukufezekisa ukuhanjiswa kwesignali ye-bidirectional optical. Oku kuthetha ukuba i-fiber optic enye isetyenziselwa ukuthumela kunye nokufumana izibonakaliso, ukufezekisa ukuhanjiswa kweempawu ze-bidirectional ngokusebenzisa ubude obuhlukeneyo okanye iindlela zokwahlula ixesha. I-fiber optic transceivers enye ingagcina ukusetyenziswa kweefiber optical kunxibelelwano lwefiber optic, kwaye ifanelekile kwezinye iimeko zesicelo ezifuna ukugcina izixhobo zefiber.

I-Multi fiber optical transceiver:

I-Multi fiber optical transceiver luhlobo lwemveli lwe-transceiver optical efuna ubuncinci iifiber ezimbini ukufezekisa ukuhanjiswa kwesignali ye-bidirectional. Ifiber optic enye isetyenziselwa ukuthumela imiqondiso, kwaye enye ifiber optic isetyenziselwa ukufumana imiqondiso. Ii-transceivers zefiber ezininzi zifuna izibonelelo ezininzi zefiber kunxibelelwano lwefiber optic, kodwa zinokubonelela ngakumbi ngokuzinza kunye nezizimeleyo zeendlela zokuhambisa i-bidirectional, ezilungele iimeko zesicelo ezineemfuno ezingqongqo zokuhambisa umqondiso.

Ukuba kuyimfuneko ukugcina izibonelelo zefiber kwaye ayifuni ukusebenza okuphezulu kakhulu kokuhanjiswa, i-fiber optical transceiver enye inokuqwalaselwa. Ukuba ijelo lothumelo elizinze ngakumbi nelizimeleyo liyafuneka kwaye lineemfuno eziphezulu zokuhanjiswa komqondiso, ke i-multifiber optical fiber transceivers inokukhethwa.

Ukuhlelwa ngokohlobo lwefayibha esebenzayo

Imodi enye ye-fiber optic transceiver:

Iitransceivers zefiber optic mode enye zifanelekile kwiinkqubo zonxibelelwano zefiber optic enye. I-fiber yemowudi enye luhlobo lwefiber ene-diameter encinci yangaphakathi ye-5-10 microns (ngokuqhelekileyo i-9 microns), enokuhambisa izibonakaliso eziphezulu ze-optical frequency. Ke ngoko, ifanelekile ukuhanjiswa komgama omde kunye nokuhanjiswa kwedatha ngesantya esiphezulu. Iitransceivers zefiber optic zemodi enye ngokuqhelekileyo zisebenzisa iilaser njengemithombo yokukhanya ephumayo, enokufikelela kumgama omde wothumelo kunye namazinga aphezulu othumelo. Oku kwenza ii-transceivers ze-fiber optic ze-single-mode zisetyenziswe ngokubanzi kwiimeko ezifuna ukuhanjiswa komgama omde njengothungelwano lwe-metropolitan area (MANs) kunye nothungelwano lwendawo ebanzi (WANs).

I-Multimode fiber optic transceiver:

I-Multimode fiber optic transceivers ifanelekile kwiinkqubo zonxibelelwano zefiber optic multimode. I-core diameter ye-multimode fiber idla ngokuba nkulu (ngokuqhelekileyo i-50 okanye i-62.5 microns) kwaye inokuxhasa iindlela ezininzi zokuhanjiswa kwesignali ye-optical. Ke i-multimode fiber transceivers ayinakudityaniswa ngokuthe ngqo kusetyenziswa ifayibha yemowudi enye. I-Multimode fiber optic transceivers ngokuqhelekileyo zisebenzisa ii-diode zokukhanya ezikhanyayo (ii-LED) njengemithombo yokukhanya ephumayo, ilungele ukuhanjiswa komgama omfutshane kunye nokuhanjiswa kwedatha ephantsi. Oku kwenza i-multimode i-fiber optic transceivers isetyenziswe ngokubanzi kwizicelo zomgama omfutshane ezifana nenethiwekhi yendawo yendawo (i-LANs) kunye noqhagamshelwano lweziko ledatha.
