Ikhebula komsindo wokubonisa

Kuze kube manje, ikhebuli zomsindo we-optical - eyodwa yezindlela zesimanje kakhulu futhi enokwethenjelwa for ukudluliswa kwedatha. Fibre ukuthumela idatha optic wenziwa usebenzisa ukukhanya. Njengoba wonke umuntu uyazi, ukukhanya - omunye sezitimela ezinejubane kakhulu emhlabeni imihlola, Ngakho-ke kubalulekile ukuba baqonde ukuthi lo ikhebula, ukuthi isebenza kanjani kanye nalokho okudingekayo.

Khanyisa kuyinto wave kagesi imvamisa high. Uma sidlula i fibre optical, kungaba kanyekanye baphathe esikhulu kakhulu inani Imininingwane. Ngakho le ndlela yokudlulisa i uzinzile futhi has a amasosha omzimba okusezingeni eliphezulu ukuze emisebeni kagesi. Lapho edabula optical fibre ukukhanya wave onakala - ke kuncike obala kanye nezinye izakhiwo emimoya i fibre optical, ikakhulukazi, i zomsindo we-optical ikhebula.

Ake sibheke kabanzi ngesibonelo ikhebula optical DAXX R07. He qamba ngengilazi Imicu yotshani ukuthi abe ezingeni eliphezulu ngale. Futhi, ine ongaphakeme ukuhlakazwa Coefficient lecinisekisa esitebeleni idatha ukusakaza futhi ijubane eliphezulu ukukhanya. Ngenxa yalezi izakhiwo, R07 zomsindo we-optical ikhebula interconnects emkhayeni kubhekwa omunye the best, ngakho-ke Ilungile ekhaya yaseshashalazini ekilasini ephezulu.

Glass fibre ikhebula kuyinto 280 Imicu yotshani esihle. Ubukhulu imicu 53 microns. fibre ngasinye lacquered ungqimba ekhethekile ukuthi has a Inkomba okusezingeni eliphezulu yezokubona - ke Akhuthaza ukwakheka kwe-ukugeleza bushelelezi yokukhanya ne ephansi okunokwenzeka attenuation. Le ndlela yokwakha yenza ukuzinza okusezingeni eliphezulu uma udlulisa esiningi idatha, yingakho i-amasignali umsindo, ikhebula optical R07 ingenye engcono.

Ekuvikeleni mechanical umonakalo emihle Strand fibre egcwele sesikhashana ekhethekile, futhi ungqimba double of polyvinylchloride esetshenziswa yokusebenza esiphezulu isakhiwo sonke. Kusukela ngokweqile ukugoba ikhebula ivikela yangaphandle inayiloni esibukweni. nezixhumi Metallic ukunikeza ukuqina isicelo.

Ngaphambi coaxial kagesi ikhebula ikhebuli yomsindo optical kunezinzuzo eziningana:

- yokukhanya unekhono adlulisa esiningi ulwazi digital;

- esebenzisa fibre optical zingenziwa phakathi kwalezi zinto zombili izingxenye inyumbazana ngenxa "umhlaba." Lokhu kuyiqiniso ikakhulukazi uma iyunithi uhlelo ikhompuyutha exhunywe kwi-umamukeli.

Eliphezulu fibre optic ikhebula kuyabiza. Ukuqaphela yayo futhi kuyabiza (kufika ku $ 40-50). Uma imishini isabelomali kunzima ukusizakala "yokukhanya", ngakho-ke kuvame kakhulu esikhundleni ikhebuli optical, abasebenzisi ukhethe eshibhile coaxial ikhebula digital.

Ngokuvamile, ochwepheshe ucelwa ukuthi ufuna ukuthenga ikhebuli kakhulu, ngoba iningi umamukeli satellite ifakwe kuphela ngokukhiphayo optical digital? Ngakho, ikhebula abathandekayo ayidingeki ikakhulukazi. Ikhwalithi satellite TV umsindo akuyona eliphezulu kakhulu (digital lomsindo wokusakaza idatha has a ongaphakeme bit), ukuze ikhebuli zomsindo we-optical, ungakwazi ukuthenga elula ngalezi zinjongo, okuyinto kubiza cishe 10-12 zamadola.
