Okwangoku, kukho abaninzi abavelisi bangaphandle nabasekhaya bei-fiber optic transceiversemarikeni, kwaye imigca yabo yemveliso nazo zizityebi kakhulu. Iindidi ze-fiber optic transceivers nazo zahlukile, ikakhulu zahlulwe kwi-rack-mounted optical transceivers, i-desktop transceivers optical kunye ne-card-type transceivers optical.

I-transceiver ye-fiber optical transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye neempawu ze-optical ezide. Ikwabizwa ngokuba yi-photoelectric converter kwiindawo ezininzi kwaye isetyenziswa kwiizixhobo zonxibelelwano zamehlo.

Ububanzi kunobubanzi.Izixhobo zokuhambisa i-fiber optical ezifana ne-transceivers optical phone kunye nezixhobo zokufikelela kwi-fiber optical zinokufikelela ukuhanjiswa phakathi kwezixhobo ngokusebenzisa i-transceivers optical. Ngokuqhelekileyo, i-transceivers optical ihlukaniswe yaba yimodi enye kunye ne-multi-mode, enye-fiber kunye ne-dual-fiber. Uhlobo lojongano olungagqibekanga yi-SC. I-FC, i-LC, njl. Umgama wothumelo ngokubanzi ziikhilomitha ezingama-25, iikhilomitha ezingama-40, iikhilomitha ezingama-60, kunye neekhilomitha ezingama-80. , iikhilomitha ezili-100, iikhilomitha ezingama-120, njl.

Imowudi enye kunye ne-multi-mode transceivers optical

Imowudi enye ithetha ukuba isignali ye-optical isasazeka ngetshaneli enye, ngelixa imowudi ye-dual okanye i-multi-mode iphantse ifana kwaye isasazwa ngeendlela ezimbini okanye ezininzi. Xa umsebenzisi ekhetha ukuba uthumele ngemowudi enye okanye ngeendlela ezininzi, eyona nto iphambili yokumisela ngumgama afuna ukuwuthumela. Ugqithiso lwemowudi enye lune-attenuation encinci, kodwa isantya sothumelo siyacotha. Ilungele ukuhanjiswa komgama omde. Ngokubanzi, umgama mkhulu kune-5 yeemayile. Kungcono ukhethe i-fiber yendlela enye. Ukuhanjiswa kwe-Multimode kune-attenuation enkulu, kodwa isantya sothumelo siyakhawuleza. Ukuhanjiswa komgama omfutshane, ngokubanzi umgama ungaphantsi kweekhilomitha ezi-5, kwaye i-multimode fiber lolona khetho lungcono.

I-fiber enye kunye ne-fiber optical transceiver ezimbini

I-fiber enye ibhekiselele kwi-fiber optical fiber enye ehambisa kwi-core enye; ifayibha ezimbini zibhekisa kwi-double-core optical fiber ethumela kwiicores ezimbini, enye ifumana kwaye enye iyasithumela. Ngokuqhelekileyo, abasebenzisi bahlala besebenzisaifayibha ezimbini, kuba i-dual-fiber inenzuzo ngakumbi ngokwexabiso. Ifiber enye isetyenziswa ngokubanzi xa intambo yokukhanya iqinile. Ngokomzekelo, ukuba i-fiber ye-12-core i-double-core, iinethiwekhi ezi-6 kuphela ezinokudluliselwa; ukuba i-fiber ye-12-coreifayibha enye, i-50% ye-wiring ingagcinwa.

FC, SC, LC transceiver optical

I-FC, i-SC, kunye ne-LC luhlobo lwe-pigtail interface, kwaye i-SC yi-interface ye-pigtail esetyenziswa kakhulu. Xa uthenga i-optical transceiver interface, qaphela ukuba olu jongano luyahambelana nepigtail interface oyinikezayo. Ewe kunjalo, kukho iintlobo ezininzi zeentambo ze-optical kwimarike, njengeFC kwelinye icala kunye ne-SC kwelinye icala.Iimodyuli ze-SFP ezibonakalayozisetyenziswa rhoqo kwi-LC.

Umgama wokuhanjiswa kwe-transceiver optical ixhomekeke kukhetho lomsebenzisi kwisicelo sangempela, kwaye umgama wokuhambisa phakathi kwezixhobo ezimbini unokukhethwa ngokwe-transceiver optical ehambelanayo.

Isishwankathelo: Xa ukhetha i-transceiver ye-fiber optical, hlawula ingqalelo ekhethekileyo kwisicelo. Ukuba i-transceiver ye-optical engalunganga ikhethiwe, inokubangela ukuba iofisi okanye i-remote phone transceiver optical okanye ezinye izixhobo zingasebenzi kakuhle okanye i-pigtail interface ayinakuqhagamshelwa. Ingxaki eneenkcukacha inokuba Dibana nomvelisi ukuqinisekisa ukuba uthenga iimpahla ezifanelekileyo.
