Qonda ama-wavelength angu-850nm, 1310nm no-1550nm ku-fiber optical
Ukukhanya kuchazwa nge-wavelength yayo, nasekuxhumaneni kwe-fiber optic, ukukhanya okusetshenzisiwe kusesifundeni se-infrared, lapho ukukhanya kwe-wavelength kukhulu kunalokho okukhanyayo. Ekukhulumisaneni kwe-fiber optical, i-wavelength ejwayelekile ingu-800 kuya ku-1600nm, kanye nama-wavelength asetshenziswa kakhulu angama-850nm, 1310nm no-1550nm.
Umthombo Wezithombe:
Lapho i-fluxlight ikhetha i-wavelength yokuhambisa, ibheka ngokulahleka kwe-fiber nokusakazeka. Umgomo ukudlulisa idatha kakhulu ngokulahleka okuncane kwe-fiber ngaphezulu kwebanga elide kakhulu. Ukulahleka kwamandla esiginali ngesikhathi sokudluliselwa ku-attenuation. I-attenuation ihlobene nobude be-waveform, isikhathi eside i-waveform, incane i-attenciation. Ukukhanya okusetshenziswe ku-fiber kunama-wavelength amade angu-850, 1310, 1550nm, ngakho-ke i-attenciation ye-fiber incane, nayo ephumela ekulahlekelweni okuncane kwe-fiber. Futhi la ma-wavelength amathathu acishe amunwe, alungele kakhulu ukudluliselwa emiculweni yokukhanya njengemithombo ekhanyayo.
Umthombo Wezithombe:
Ekuxhumaneni kwe-fiber optical, i-fiber optical ingahlukaniswa ibe yimodi eyodwa nemodi ehlukahlukene. Isifunda se-850nm Wavelength imvamisa iyindlela yokuxhumana ye-Multi-Mode Optical fiber, i-1550nm imodi eyodwa, futhi i-1310NM inezinhlobo ezimbili zemodi eyodwa nemodi ehlukahlukene. Kubhekiswa ku-ITU-T, i-AtTenuation ka-1310NM inconyelwe ukuba yi-≤0.4DB / km, kanye ne-attenciation ka-1550nm yi-≤0.3DB / km. Futhi ukulahleka ku-850nm yi-2.5DB / km. Ukulahleka kwe-fiber kuvame ukwehla njengoba i-wavelength yakhuphuka. Isikhungo se-wavegth ka-1550 nm ezungeze i-C-band (1525-1565nm) kuvame ukubizwa ngokuthi iwindi lokulahleka kwe-zero, okusho ukuthi i-atchation ye-quartz fiber incane kunazo zonke kule wavelength.
I-Beijing Rofea Optoelectoronics Co, Ltd. Inkampani yethu isebenza ngokukhethekile ocwaningweni oluzimele kanye nentuthuko, ukuklama, ukukhiqiza, ukuthengiswa kwemikhiqizo ye-opoleectronic, futhi kunikeze izixazululo ezintsha kanye nezinsizakalo ezenziwe ngezifiso zabaphenyi besayensi nonjiniyela bezimboni. Ngemuva kweminyaka yokuqamba okuzimele, kwakha uchungechunge olucebile futhi oluphelele lwemikhiqizo yezithombe, esetshenziswa kabanzi kumasipala, ezempi, ezokuhamba, amandla kagesi, ezezimali, ezemfundo, ezemfundo.
